Let us calibrate. Let us eradicate. Let Us Drone.

In a perfect world, we would be able to fly our drones whenever and wherever we felt like it; never getting any errors or malfunctions. But this world isn’s perfect, and we have annoying things like jobs that dictate when we can fly, and the FAA to say where we can fly. When Saturday finally does come around and our location is in the green, we get VPS errors *sigh*. All is not bad though, it’s still Saturday, and I’m going to tell you how to get rid of those vision system errors on your Phantom 4 Pro.

In this post, we will talk about common reasons for vision system errors on the Phantom 4 Pro (applicable to the other Phantom 4’s) and how to calibrate the vision system to eradicate those errors. 

What is the Vision System

DJI has worked very hard to make their drones user-friendly. The remote control helicopters I would fly as a teenager were incredibly difficult to maneuver compared to any of DJI’s drone lineup. Why is this? The incorporation of GPS and a Vision Positioning System (VPS) to keep the aircraft extremely steady are certainly two of the reasons.

The Vision System on the Phantom 4 Pro is comprised of two ultrasonic sensors (located on the bottom) and three stereo vision sensors (located on the back, front and bottom).

Ultrasonic sensors emit high-frequency sound waves that bounce off surfaces back to the drone to provide distances of objects.

Stereo vision sensors are cameras that feed images to the drones processor, which is then able to identify the depth of objects by using software that assigns colors to corresponding distances.

This is a basic description of the VPS, and although not part of the VPS, I should note that the Phantom 4 Pro (and P4 Pro V2.0) have infrared sensors on the sides as well. What isn’t widely known is that those infrared sensors only work when the drone is in beginner or Tripod mode. Sure, it’s still nice to have them, but don’t expect the infrared sensors to save your butt if you’re rolling towards a wall at 20 MPH.

If you have the original Phantom 4 or Phantom 4 Advanced, you will not have sensors on the back or sides of your drone.

Common reasons for Vision System errors

Ever receive one of the following messages while flying your Phantom 4 Pro?

• “Downward Vision Sensor Calibration Error. Precision Landing May Fail”. Well, that’s not good.
• “Vision Sensor Communication Error (10c00)”
• “Vision System Error”
• “Forward Vision Sensor Calibration Error. Precision Landing and Obstacle Avoidance May Fail”
• “Restart Aircraft. Contact DJI Support if the Problem Persists.”
• “Vision System Error (f00400)”
• “Recalibrate Vision System using DJI Assistant 2”
• “Recalibrate the Vision System. Use DJI Assistant on Mac or PC.”

It may be difficult to ascertain why you are getting errors with the VPS, but I have compiled a list of some common instances where people have gotten errors.

Problem: You may get an error or the drones VPS might just not operate correctly when flying over water. This is clearly stated in the manual: “The performance of your Vision System and Infrared Sensing System are affected by the surface being flown over”, and under the types of surfaces listed we see “Flying over water or transparent surfaces”.
Solution: A lot of people have recommended turning off the VPS when flying over water. I usually don’t (unless I am flying low), but it is worth a shot if you are getting errors or notice erratic behavior while flying over water. To disable vision positioning, go to settings>visual navigation settings>advanced settings>enable vision positioning. 

Problem: You receive a vision system error after a firmware update. 
Solution: Try calibrating the VPS. If that doesn’t work, try refreshing the firmware. You can refresh the firmware with DJI Assistant 2 or within the DJI GO 4 App.

Problem: You receive a vision system error with your brand new drone. 
Solution: Calibrate the VPS. We all know how much of bumpy ride packages go through in the mail, and your P4 Pro doesn’t love all that jarring action.

Problem: VPS error after a crash.
Solution: Well, we can’t be too surprised if we get a VPS error, along with a few other errors if you crash the drone. Not only should you calibrate the VPS after a crash, but it would also be wise to calibrate the IMU and compass. Do a thorough inspection of the drone to make sure everything is structurally sound as well!

Problem: VPS error after a DJI GO 4 App update. 
Solution: Forceclose the app and see if the error is still present upon reopening it. If it’s still there, delete the app and download it again. If none of this works, consider rolling back the app to the previous version. I can’t speak much to this as I have never tried it, but here are YouTube tutorials on how to undertake such a task: click here for Apple, and here for Android.

Problem: VPS error after installing the HDMI output module.
Solution: After installing the HDMI module it is very important to refresh the firmware, even your AC and RC are currently on the latest firmware update.

Problem: VPS error after the drone came into contact with moisture. A guy reported that after landing in the snow he got a VPS error, but the drone wouldn’t calibrate with DJI Assistant 2. Turns out moisture had fogged up one of the downward stereo vision sensors.
Solution: After letting it dry out for a couple of days he was able to calibrate the VPS with no problem.

Problem: You may have a bad VPS module. 
Solution: If you’ve tried everything and are still getting vision system errors, there is a chance that the VPS module is bad. DJI offers a 6-month limited warranty for the VPS on the Phantom 4 Pro. In my article Is My DJI Drone or Gimbal Under Warranty? Check Here I explain how to go about initiating a return.

How to calibrate the Vision System on the P4 Pro 

Calibrating the vision system is a relatively simple process, and it takes about five minutes. You will need DJI Assistant 2 for the calibration.

1. Make sure that you are on the latest firmware update.
2. If you haven’t already, download DJI Assistant 2 from DJI’s website here.
3. Set the resolution of your computer screen to 1600×900.
4. Ensure that you have at least a 50% charge in your battery.
5. Connect your Phantom 4 Pro to a computer with a USB cable.
6. Power on the drone.
7. Launch DJI Assistant 2.
8. Click on Phantom 4 Pro.
9. Click on “Calibration” which you should see on the lefthand menu.
10. Follow the tutorial that will walk you through the steps of calibrating. Note: when I was calibrating the downward sensors, the gimbal make a funny sound, like it was screaming at me. After researching this, others have heard the same sound and claimed that it was “normal”. 
11. After you have tilted your drone in every which way, DJI assistant 2 will begin the calibration, which takes about a minute.
12. Upon completion of the calibration process, DJI Assistant 2 will ask you to restart the drone.
13. Ta-da! You did it, and hopefully, all VPS errors will be gone when you open DJI GO 4.

If you’d prefer, here is a YouTube tutorial video that walks you through each step.

It’s very important to set the screen resolution

In order for the calibration to work, your computers screen resolution should be set to 1600 x 900. I have an older 27″ iMac which has a default screen resolution of 2560 x 1440, and I could not calibrate the VPS. I kept getting a “Frame Alignment Error”, and when I clicked on “calibrate” I was met with a white screen.  I kept thinking “where are those darn dots that I see in the tutorial video”. Well, after conducting some research I learned that the resolution needs to be set to 1600 x 900. When I changed the screen resolution under the display settings, the calibration worked flawlessly.

If you have an Apple computer, go to settings>displays>scaled>click 1600 x 900. If you have a PC, the steps may be a bit different, but there should still be a “displays” section under settings where you can adjust the resolution.

Trevor’s take

I’ll admit it, I can be lazy. I flew for months with a message on the DJI GO 4 App that read “Recalibrate the Vision System. Use DJI Assistant on Mac or PC.” When I went to calibrate the VPS on my iMac, I ran into the issue I mentioned above where the screen resolution was too large. I didn’t know that the screen resolution size was the culprit at the time, and I was too lazy to figure out why because, after all, my drone seemed to be flying just fine. When I realized how simple the remedy was, I frowned at myself for dragging my feet.

If you’re reading this and currently have a VPS error message displaying on your app, I hope that this post provided some value for ya. What’s your experience with the vision positioning system? Have you experienced other errors or problems that weren’t mentioned above? Comment below!

Было падение Mavic с небольшой высоты. Повредился шлейф подвеса камеры и пластина крепления камеры. После замены шлейфа и пластины, подвес заработал стабильно, но камера не работает — выдает ошибку Camera sensor error.

Есть какие-нибудь советы? Может-быть плохо «пристегнулся» шлейф? Или еще что? Или все плохо? 🙁

RimmerGo , по моему тоже все ОК — лучше не будет, это все же не профессиональная техника с сумасшедшей светосилой и скорострельностью. Но перфекционизм понимаю :-))))

Съемке горнолыжных спусков это повредить не должно (ИМХО), поскольку там самое выразительное — «наезды-отъезды», а если речь про отслеживание летящего лыжника быстрым поворотом коптера, то фон будет размыт, а движущийся объект — резкий, что очень добавит художественной выразительности. Но потренироваться так снимать придется немало: даже фото «с проводкой» снять непросто, а уж видео.

В общем мое ИМХО: для видео качество ОК, если нет намерения вырезать стопкадры из кусков во время поворотов. В каком-то учебном видео на ютубе даже учат специально одевать фильтр чтобы снижать освещенность и заставлять камеру делать бОльшую выдержку — для смаза во время движения, чтоб более «киношной» картинка была.

Честно: «смаз во время движения» снимая с коптера получить очень сложно. Думаю, что невозможно. Хотя, в если только в постредактировании. Но не при 30 к/сек.

Хороший кадр смаза . Но не с коптера. Кадр не мой. Взят с костромского форума.

DJI Phantom 4/ Pro Error Codes and How to Fix Them!

It’s normal to get error codes and messages when using Phantom 4 and it’s better to get some knowledge about those things and how to fix those issues. I went through many DJI forums and collected several error codes and how to fix them.

Hope this article would help with solving your Phantom 4 Error codes. Below, There is the list of error codes I was able to collect from DJI forums.

Common DJI Phantom 4/ 4 Pro Error Codes.

• Error 1: DJI Phantom 4 Error Code 50 (IMU Error).
• Error 2: DJI Phantom 4 Battery Error.
• Error 3: DJI Phantom 4 ESC Status Error.
• Error 4: DJI Phantom 4 Compass Error (COMPASS-ERR).
• Error 5: DJI Phantom 4 GPS Error.
• Error 6: DJI Phantom 4 Camera Sensor Error.

Error 1: DJI Phantom 4 Error Code 50 (IMU Error).

Phantom 4 Error Code 50 is an IMU calibration error and many Phantom 4 users get this error because of performing the calibration process near metal structures while calibrating the IMU. Also outdated Phantom 4 firmware, and glitched firmware also could cause the issue.

Solutions.

• Update Phantom 4 firmware. Outdated firmware and firmware glitches can mess up the IMU calibration process. Therefore make sure to keep the firmware updated when you perform any calibration. Read How to Update DJI Phantom 4 firmware if you need to.
• Perform the IMU calibration process in a proper environment. When calibrating IMU you need to pay attention to the surroundings. For example, you should perform the process on a flat surface and should keep metal and electronics away from the aircraft. Also, you should perform the steps properly. Read the How to Calibrate IMU article for a detailed explanation of IMU calibration.
• Factory Reset Phantom 4. Download and install DJI Assistant 2 application to the PC. Connect Phantom 4 aircraft to the PC. Open the DJI Assistant 2 application and log in to your DJI account and choose Phantom 4. Then go to the “Firmware Updates” tab and click on “Factory Reset”.
• Change Location and try again.

Error 2: DJI Phantom 4 Battery Error.

Usually, DJI Phantom 4 battery error pops because of an imbalance in battery cells, faulty power management board, and battery firmware glitches.

Solutions.

• Refresh battery firmware. Update Phantom 4 firmware while keeping the glitched battery inside. Read How to Update DJI Phantom 4 firmware.
• Drain the battery to zero and recharge it fully.
• Change the battery.
• Change power management board. If the error still exists, the power management board might be glitched or damaged. So you would have to change the power management board. Advisable to contact DJI Support.

Error 3: DJI Phantom 4 ESC Status Error.

Usually, ESC status error can be caused by outdated firmware and faulty electronic speed controller (ESC).

Solutions.

• Update Phantom 4 firmware.
• Replace ESC.

Error 4: DJI Phantom 4 Compass Error (COMPASS-ERR).

In most cases, Phantom 4 Compass Error pops up because of placing and flying the aircraft near a magnetic field. Once the aircraft is placed near a magnetic field, it assumes the artificial magnetic field as the earth’s natural magnetic field. Then it pops “Compass Error” when the Phantom 4 checks its orientation against its GPS position and finds a discrepancy.

Solutions.

• Avoid Electromagnetic interference. Fly the Phantom 4 away from powerlines, communication towers, huge buildings, etc.
• Calibrate the compass in an open wide area. Move away from the place where you currently receive Compass Error to an open area. Then perform a proper compass calibration on Phantom 4. Read how to calibrate the compass.
• Contact DJI. If you still get the error, it’s better to contact DJI for repair.

Error 5: DJI Phantom 4 GPS Error.

DJI Phantom 4 GPS Error is usually caused by firmware issues, DJI GO 4 app issues, miscalibrated compass, and GPS module glitches.

Solutions.

• Update DJI GO 4 app to the latest version. Visit DJI Downloads Center and download and install the latest DJI GO 4 app.
• Update or refresh Phantom 4 firmware. Read How to Update DJI Phantom 4 firmware.
• Calibrate Phantom 4 compass.
• Replace the GPS module. If you still facing the issue, the GPS module might be glitched or damaged. So you need to replace this. Better to contact DJI to replace or fix the issue.

Error 6: DJI Phantom 4 Camera Sensor Error.

In most cases, DJI Phantom 4 does not show any camera view and pops camera sensor error, chances are the ribbon cable to the camera is damaged.

Solution.

• Replace the Camera ribbon cable. Buy Phantom 4/ 4 Pro Ribbon cable for about 40$ and replace the current ribbon cable. Here is a demonstation video from the youtube.

Восстанавливаю найденный в поле Mavic Pro. Судя по датам записей на флешке, пролежал он в траве ровно 11 месяцев. Судя по состоянию, не упал, а сел.

Аккум добрые люди разблокировали. Очистил аппарат от грязи, разобрал весь. На удивление оказался довольно герметичен. Особых повреждений не нашёл. Промыл всё и все разъёмы спиртом и очистителем контактов. Собрал. С первого запуска (пока на столе) всё заработало, за исключением передних сенсоров — ошибка по обоим вывалилась сразу. При просмотре в DJI Assistant выдал «несоответствие прошивки некоторым модулям» — обновил, по сенсорам ничего не изменилось.

Разобрал снова, снял сенсоры, осмотрел ещё раз шлейфы и разъёмы — криминала не нашёл.

Вопрос к опытным товарищам — куда копать ? Два сенсора или шлейфа сдохли одновременно ? Или однозначно плата подвеса ?

Сенсоры снимал, плюс 1 минута к полёту. Смотреть надо куда едешь летишь! Пишет — «ошибка сенсоров» ну и что, всё летает.

Таких ошибок как у Вас с отключенными сенсорами не выдаёт.

Я про передние сенсоры если что.

Может стоит прошить другой.

Knowing how to calibrate the Mavic 2 Pro and Zoom vision sensors is very important.

If your are receiving the Mavic 2 Vision system error, or if your quadcopter is flying erratically, not hovering correctly, then you need to calibrate the Mavic 2 Vision Positioning System.

Also, if the Mavic 2 vision system is not working correctly, then it may not detect and avoid obstacles.

Below are the instructions on how to calibrate the Mavic 2 Pro and Zoom vision system including videos.  You will also find tips to fix the Mavic 2 vision sensor and system errors.

If you are flying your Mavic 2 and the Vision Sensor Calibration error or Vision System Error occurs, you need to fly the quadcopter in straight away and re-calibrate the Mavic 2 VPS using the below instructions.

If the Mavic 2 calibration doesn’t fix the flying difficulties, then check to see if there is a Mavic 2 update available and use the excellent tips below to fix the Mavic 2 vision system error.

The full Mavic 2 calibration is done with the DJI Assistant 2 software. However, if you have no computer with you, then you can perform a quick vision sensor calibration using the DJI Go 4 app.

If you have the original Mavic Pro, then you visit our Mavic Pro vision calibration article as there are differences in the Mavic Pro and Mavic 2 vision system calibration.

Below are the instructions to calibrate the Mavic 2 Pro and Zoom vision system to fix errors while flying, hovering or obstacle sense and avoid issues.

• Download the DJI Assistant app (Apply and Windows versions available).
• Remove the Mavic 2 propellers.
• Power on the Mavic 2 quadcopter.
• Connect the quadcopter to a computer using a USB cable.
• Launch the DJI Assistant 2 application on your computer.
• Select Mavic 2.
• Click Calibration on the left side in the DJI Assistant 2 software.
• Watch the tutorial a couple of times, which show you how to calibrate the Mavic 2.
• Click Next and Calibration Now.
• Face the Mavic 2 front sensors at the computer screen.
• Adjust the Mavic 2 position so that the green rectangle is covered by the red rectangle.
• Keep the Mavic 2 in its current position and slowly move the drone along with the blue background.
• When the Mavic 2 forward vision sensors are calibrated a prompt will pop up, stating Forward Camera Calibration Complete with a green check mark.
• Click Start Downward Camera Calibration to continue.
• Keep the Mavic 2 with its downward vision sensor in its current position facing the computer and slowly move the drone along with the blue background.
• When the Mavic 2 downward vision sensors are calibrated a prompt will pop up stating Downward Camera Calibration Complete.
• Click Start Rear Camera Calibration to continue.
• Keep the Mavic 2 with its backward vision sensor in its current position facing the computer and slowly move the drone along with the blue background.
• When the Mavic 2 backward vision sensors are calibrated a prompt will pop up stating Rear Camera Calibration Complete.
• Next, fold the back legs under the Mavic 2 before starting to calibrate the side vision sensors.
• You won’t be able to fold the back leg fully on the side which has the USB cable on.  That is OK.
• First, hold the Mavic 2 with the right side, which contains the USB cable to face the computer and move the quadcopter along with the blue background.
• When this side sensor is calibrated a pop up box will state Right Camera Calibration Complete.
• Then turn the Mavic 2 to the left side and calibrate by following the blue boxes on screen.
• After both sides of the Mavic 2 are calibrated, the DJI Assistant performs calculations. If calibration is successful, you will see a green check mark with Calibration Complete message.
• Then restart your Mavic 2 drone to complete the calibration.

Below is an excellent Mavic 2 calibration tutorial video.

Calibrate Mavic 2 Vision Sensor Using DJI Go 4

It is possible to do a quick calibration of the Mavic 2 vision sensors using the DJI Go 4 app. This could be a quick fix if you receive the DJI Mavic Vision Sensor Calibration error or Vision System Error.

Other reasons to calibrate the Mavic 2 VPS is if you feel the Mavic 2 isn’t hovering as stable as it normally does or if you feel the Mavic 2 is slow detecting obstacles or just not flying as it should.

If you don’t have a laptop with the DJI Assistant 2 app to do a full Mavic vision sensor calibration, then you can do a quick Mavic vision sensor calibration using the DJI Go 4 app.

To do the quick Mavic vision calibration, tap on the Aircraft Status in the DJI Go 4 app. Then click on Vision Sensors and start the quick calibration.

What To Do If Mavic 2 Vision Sensor Calibration Fails

1. Insure that you have the latest Mavic 2 firmware before calibrating the vision sensors.
2. Only calibrate the Vision Sensors when the light is good and never calibrate near or over reflective surfaces.
3. Remove the propellers before starting the calibration.
4. It is best to have batteries full or as close to full on your laptop and Mavic 2 just in case the vision sensor calibration takes longer.
5. Give yourself plenty of space and have no interruptions while you calibrate the Mavic 2 vision sensors.
6. Calibration of the Mavic 2 vision sensors require more or less only wrist movement to pivot, tilt and rotate the drone to follow the blue squares on the screen.
7. Insure you fingers aren’t covering or close to the vision sensors while calibrating the Mavic 2.
8. Leave the Mavic 2 on during the full process until you see the “Calibration Complete” message.
9. Don’t forget to restart the Mavic 2 after calibration.
10. If you are using a laptop and the DJI Assistant 2 is not properly recognizing the Mavic 2 sensors, then try it on a normal desktop computer with external display.

Fix Mavic 2 Vision System Error

The Mavic 2 vision system error does not have to be coming from the vision sensors. It could be caused by the infrared sensors, which are part of the whole Mavic 2 Vision Positioning System. So the process of calibrating the vision sensors would not correct the system error if the problem is with the infrared sensors.

If you’re quadcopter is only new and you are receiving the Mavic 2 vision system error, it is important to troubleshoot the problem as quickly as possible.

With all new DJI products, there is always the option to return the quadcopter but this return period is not very long. However, don’t send it straight back without checking the Mavic 2 and following the below steps as it could be something very simple causing the Mavic 2 vision system error.

Here are some instructions on what to try when you receive the DJI Mavic Vision system errors.

1. If the Mavic is only new, check that there is no tape or packaging covering the vision sensors on the forward, rear, downward and both sides.
2. Switch off the Mavic 2, take the battery out and leave it off for about 3 minutes.
3. If the light is insufficient, then the Mavic 2 vision sensors won’t work properly. See below.
4. The Mavic 2 vision system won’t work correctly or not at all over polished or reflective surfaces giving cause to the vision sensor See below.
5. Ensure the vision sensors are clean. Use a soft cloth to remove any dust or debris from the sensors.
6. Check other parts of your Mavic 2. If the quadcopter isn’t flying correctly because of bent or broken propellers or other parts,  then incorrect information will be sent back to the flight controller, which could lead to the to the system error.
7. Check to see if there is new Mavic 2 firmware available.
8. Calibrate the Mavic 2 vision sensors using DJI Assistant 2 software  as described above.
9. Try the DJI Go 4 Mavic quick calibration described above.
10. Check that you are getting a strong GPS signal in P-Mode.
11. Calibrate the Mavic 2. If the IMU / compass is not calibrated, the flight control system will not receiving correct information and this may effect the vision system error.

As well as vision sensor issues, you may be having issues where the Mavic disconnects from the Remote Control or DJI Go 4 app.

If you are experiencing these Mavic 2 disconnect issues, then read our article on fixing Mavic Pro and Mavic 2 disconnects. The article covers all the many reasons which can cause the drone disconnecting from the remote or DJI Go 4 app. Looks at cables, ports, SD cards, smartphone cache, app settings and more.

Performance Of The Mavic 2 Vision System

The Mavic Vision System is affected by its surroundings with the infrared sensor under the Mavic been affected greatly by the surfaces it is being flown over.

Here are some notes on instances and surroundings which can adversely affect your Mavic Vision system;

• Flying over monochrome surfaces such as pure black, white, pure red, pure green.
• Flying over reflective surfaces.
• Flying over transparent surfaces.
• Flying over moving objects or surfaces.
• Flying over surfaces that strongly reflect infrared waves away such as mirrors.
• Flying at high speeds of over 31 mph forward and 27 mph backward to allow the Mavic 2 sufficient time to brake.
• Flying over small and fine objects such as power lines or tree branches.
• Flying when the lighting changes frequently and drastically.
• Flying over extremely dark surfaces. (< 10 lux) or very bright (> lux 40,000).
• Flying over surfaces without a clear pattern or texture.
• Flying over surfaces with identical repeating patterns.

Note: If you require components for your quadcopter, then view this large selection of Mavic 2 parts, upgrades and accessories.

Mavic 2 Obstacle Sensing Vision System Information

The new Mavic 2 Pro and Zoom can sense objects in 6 directions.  Known as Omnidirectional Obstacle Sensing, this includes left, right, up, down, forward and backward obstacle sensing.

Obstacle sensing for left and right directions is only available in ActiveTrack or Tripod Mode.

Now, while all 6 sides of the Mavic 2 are covered for obstacle sensing, Omnidirectional Obstacle Sensing does not fully cover the full 360 degree circumference arc of the quadcopter.

Please see the DJI Mavic 2 user manual for diagrams showing the obstacle sensing coverage around the quadcopter.

How the Mavic 2 Obstacle Sensing Works

The Mavic 2 Pro and Mavic 2 Zoom are equipped with Forward, Backward, Downward and Lateral Vision Systems including Upward and Downward Infrared Sensing Systems. These all provide omnidirectional obstacle detection, providing lighting conditions are adequate.

The main components of the Forward, Backward and Downward Vision Systems are 6 camera sensors located on the nose, rear end and underside of the Mavic 2 quadcopter.

The lateral Vision System are 2 cameras with one camera on each side of the Mavic 2 quadcopter.

The main components of the Upward and Downward Infrared Sensing Systems are 2 x 3D infrared modules located on the top and underside of the Mavic 2 quadcopter.

The Downward Vision System and Infrared Sensing System helps the Mavic 2 maintain its current position and hover in place very precisely. The Vision and Infrared Sensing system allow the Mavic 2 to fly indoors or in other areas where a GPS signal is unavailable.

Mavic 2 Bottom Auxiliary Light

The Auxiliary light located on the underside of the Mavic 2 improves visibility for the Downward Vision System in bad light conditions.

Obstacle Sensing is fascinating technology and you can read further in this article entitled “Top Collision Avoidance Drones And Obstacle Detection Explained“.

Here is a shorter version from DJI on how to calibrate the Mavic 2 VPS.

A time may come when you receive an “Abnormal” status notification in your DJI Go 4 app. You click it and you receive another message saying “Recalibrate the Vision System. Use DJI Assistant on Mac or PC.“

It is really important that you don’t ignore this message. Even though you can fly your drone in this state, it is not safe to do so. You may hurt someone due to your drone misbehaving or you could just crash your drone, and all that because your drone is lacking of one of its main features, vision sensors.

So, in order to continue practicing safe flight, you must know how to recalibrate vision sensors on a DJI drone. In this article, I am going to show you a step by step guide on how to do this, along with a video preview, so you don’t make any mistakes.

1. Install DJI Assistant

First, go to the DJI Assistant download page and get one that suits your drone, but be careful not to get the wrong version.

Click “Download exe” if you wish to directly install the application to your computer. Then open the .exe file and install the Assistant. After you installed it, start the Assistant.

2. Connect the drone to the PC

It’s a good idea to remove propellers from a drone. You will see me skipping that part in the video (I forgot), but you should do it just in case. The safer, the better!

Then make sure your drone battery is charged (it doesn’t need to be a full charge, 50% will be enough), and turn it on.

After turning on the drone and connect it to the PC via cable (in my case it was a USB-C cable that arrived with the Mavic Air). DJI Assistant interface will change and your drone icon will appear on the screen. Click it, and you will be taken to another window with options that are available for your drone.

On the left-hand side menu, choose “Calibration”. You will be greeted with few animations that will show you wrong and right techniques for calibrating the drone. Watch them carefully.

3. Calibrate your drone

After you “Next-ed” all of the animations, click “Calibrate Now.”

You will have to align the drone with the screen as I did in the video, and just like you saw in tutorial animations before the calibration, then follow the pattern.

You must do this for each set of sensors you have. Mavic Air has Front, Bottom and Back sensors, so I had to calibrate all of them.

4. Finishing the calibration process

If you completed each task you were asked to do, then you will see that window from the beginning, and it will say “Calculating…”. This means it collected all the necessary data and it’s now adjusting your sensors.

This step will last just a few seconds. After it’s done and you will get a “Calibration Success!” message and now you can exit the DJI Assistant and unplug and turn off your drone.

5. The Video Tutorial

6. The List of Steps

1. Visit the DJI website and download and install the software.
2. Run DJI Assistant.
3. Make sure your drone battery is at least 50% charged.
4. Remove the propellers from your drone.
5. Turn on your drone.
6. Connect the drone to the desktop/laptop via USB cable.
7. DJI Assistant will automatically recognize that your drone is connected.
8. Select the box with your drone on it.
9. In the new window, on the left-hand side, click on “Calibration”.
10. Carefully inspect DOs and DON’Ts that the Assistant will show you.
11. After you “next-ed” all steps click on “Start Calibration”.
12. Carefully place the drone in front of the screen at the right distance from the screen. Start with the drone almost touching the middle of your screen, and then move it away from the screen until the corners of the blue square become blue.
13. Track the squares without moving your drone around. Keep it in place and just tilt rotate it.
14. Next, you will need to take a step back and repeat the process.
15. After you do both Close and Far calibration of one set of sensors, you will be asked to calibrate the next set (if you have it).
16. When all vision sensors are calibrated, DJI Assistant will then calculate the data it collected, and it will upload the new settings to your drone.
17. After it’s done and you will get a “Calibration Success!” message and now you can exit the DJI Assistant and unplug and turn off your drone.

7. Congratulations!

You have completed the calibration.
