DJI Backward vision sensor calibration error is another common error related to the vision sensors. I have seen many DJI Mavic and Phantom users asking for solutions on many DJI forums.
Vision sensors (including backward sensors) are so important for a safe flight. Therefore the backward vision sensor error can’t be ignored. I also went through many forums and youtube videos and researched about the backward vision sensor error and how to fix it. So in this article let’s talk about the causes of the backward vision sensor calibration error and how to fix that error.
Causes of Backward Vision Sensor Error.
First, let’s talk briefly about the causes of backward vision sensor calibration errors.
1. Miscalibrated backward vision sensors.
As I think, in most cases, miscalibrated backward vision sensors are one of a main reason for backward vision sensor error. Miscalibrated backward vision sensors collect faulty sensor data and as a consequence, the system would detect the backward vision sensor error.
2. Outdated firmware and firmware glitches.
Firmware is responsible for managing data that are fed from inputs (including vision sensors), detecting errors, and many more activities. So having installed firmware with glitches or outdated firmware could lead to malfunctioning the system. Including mismanagement of vision sensor data that could cause this error.
3. Covered backward vision sensor surface.
Usually, flying or storing the aircraft in a dusty or foggy environment cause covering the vision sensor surface with dust or fog. Having covered vision sensor surface with fog or dust makes it harder to gather surrounding data. So the system would detect it as a sensor error.
4. Faulty backward vision sensor data.
Faulty vision sensor data is another reason for backward vision sensor error. So having temporary or permanent data or settings related to backward vision sensors also could cause this error.
5. Damaged or faulty vision sensors.
It’s so obvious that faulty or damaged backward vision sensors could cause the error. but this is the worst case when it comes to vision sensor error. If the aircraft is crashed recently or this is the first time using the aircraft, it’s fair to suspect whether the vision sensors are damaged or faulty.
How to Fix Backward Vision Sensor Calibration Error.
Next, let’s go through the step-by-step process of fixing the backward vision sensor error.
1. Reset the DJI aircraft.
Resetting the aircraft would clear temporary data and settings of the aircraft. So if any temporary data or settings cause this error, resetting the aircraft would fix the error.
2. Clean backward vision sensor surface.
As I said before, having a clear vision sensor surface is so important to work them properly. So use a soft cloth or cotton bud and clean the surface of the aircraft’s backward sensors and restart the aircraft and check whether the error is gone.
3. Refresh/Update/Downgrade the firmware using DJI Assistant 2.
According to many users, updating the firmware is an effective step in fixing this error. So next, let’s update or refresh the firmware using the DJI Assistant 2. I emphasize using the DJI Assistant 2 for updating the firmware because it reduces the risk of having faulty firmware.
- Download and install DJI Assistant from the DJI Download center to the PC.
- Connect the DJI aircraft to the computer using a micro USB cable and power on the aircraft.
- Open DJI Assistant 2 application on the PC and log in to your DJI account.
- Then select your DJI Drone and click on the “Firmware Updates” on the left panel and click on the “Upgrade” option.
- Click on “Start Update”.
- Wait until the firmware is completely downloaded and installed.
- Follow the same steps with the remote controller and update the controller’s firmware.
Then restart the aircraft and check whether the error is gone. Else, let’s go to the next step.
4. Factory reset the aircraft.
Factory resetting aircraft would erase permanently stored data and settings (including faulty settings and data.) and then back them to faulty data and settings. So next rest the aircraft to fix the error.
How to Reset the DJI aircraft.
- First Download and install DJI Assistant 2 and connect the aircraft to the PC and turn it on.
- Open DJI Assistant 2 application and log in to your DJI account. Once you logged choose DJI drone and hit “Factory Restore Defaults”. Then wait until the process completes.
5. Calibrate Forward Vision Sensors using DJI Assistant 2.
Have a high hope for this step. Because many users were able to fix the backward vision sensor error after calibrating vision sensors. So let’s calibrate the DJI aircraft’s vision sensors.
- Download and install DJI Assistant from the DJI Download center to the PC.
- Then connect the aircraft to the PC through a micro USB cable.
- Then power on the aircraft.
- Open DJI Assistant 2 application on the PC and log in to your DJI account.
- Then choose the DJI drone and click on the “Calibrate” on the left panel. Then you will be directed to the tutorial of vision sensor calibration. (Check out the below video which demonstrates the process of vision calibration clearly.)
- Follow those demonstrations and calibrate the vision sensors properly.
6. Contact Professionals or DJI Support.
Read the detailed article: How to get DJI Support to repair/fix your DJI drone issue.
If you are struggling with the backward sensor error, your aircraft’s backward vision sensors might be damaged or the circuit is faulty. So it required professional supervision. If you can contact DJI Support and repair or replace the aircraft via the DJI, definitely go that way. Else, contact professionals and get help to repair the aircarft.
