Hello,

I would like to know when the Assistant 2 will have the sensor calibration feature for the Mini 4 Pro?

Thanks,

Hi, there. Thank you for reaching out. Currently, DJI Mini 4 Pro does not support using DJI Assistant 2 for vision calibration.

Vision system may need to be calibrated after being stored for an extended period. A prompt will appear in DJI Fly, then tap the prompt and calibration will be performed automatically. We thank you for your understanding.

Hi, thanks for replying. My Mini 4 Pro had a small accident after which it's sensing obstacles even when there's none. I haven't seen any prompt to calibrate the vision system so far, any option i can use in the RC N2 to do this manually?

Hi, there. Thank you for your clarification. The vision sensor can't be calibrated proactively as the app will automatically prompt if needed. However, if you notice any unusual behavior from your drone after the incident, you may contact us at www.dji.com/support (Contact Us) I hope this information helps. Thank you for your understanding.

Same problem here... detecting obstacles even 100m high after a small fall. I contacted DJI support, no solution was successful

With the recent updates, did you notice anything different? The remote is not detecting that many obstacles when i fly now, i would say none at all.

Good evening, I bought two mini 4 pro, and both are requesting sensor calibration, how can this happen and prevent us from using them, without the possibility of making these adjustments via Assistant, I would like an opinion on resolving these problems , as the Drones are now stopped and unused, as they do not take off, even disabling sensors

Hi there, thank you for reaching out and we're sorry to hear you're facing the same issue. Kindly inform us the full details of the issue that you experienced with your DJI product, and we will surely provide you with an accurate resolution after we review the details. Rest assured that we're committed to providing the best experience for our users.

Looking forward to your response. Thank you for your support!

Going to throw it in here that the issue Mini 4 Pro's are experiencing where the drone in doing the wave in the air is caused by the collision avoidance system seemingly repeatedly sensing something thats not there and slamming on the brakes, and then applying the throttle, over and over again as it attemps to fly through the air. Turn off the collision avoidance and this behavior stops immediately.

Turn off the collision avoidance and this behavior stops immediately.

Hi there,

We are truly sorry for the inconvenience you are experiencing.

Could you try the steps below;
1. Please check whether the aircraft takes off when the issue occurs.
All the vision sensors are disabled to save power consumption when the aircraft isn’t in flight. When the aircraft takes off, all the vision sensors will be enabled.
2. Check whether the aircraft is in Sport mode.
> If the aircraft is in Sport mode, the vision sensors are disabled by default, and obstacle avoidance is unavailable.
3. Turn off the Vision Positioning and Obstacle Sensing. Only for issue with DJI Mavic 3 consumer series, DJI Mini 4 Pro, and DJI Air 3. (Vision Positioning and Obstacle Sensing function will disable all the vision sensors including the downward vision. Currently this features only available for the DJI Mavic 3 consumer series, DJI Mini 4 Pro, and DJI Air 3 after the firmware update. )
4. Check whether the flight environment meets the operating conditions of the vision sensors. For example, the flight environment should not be too dark. For detailed conditions, please refer to the User Manual.
5. Check whether the vision sensors are blocked by foreign objects or a mounted third-party accessory. Remove the foreign matter or accessory, restart the aircraft, and try again.

Upon all the steps above issue still persist please submit repair request a here >  DJI Repair

I hope this information has helped to clarify your inquiries. If you have any other questions, kindly let us know. Thank You!

Hi there,

Vision system cameras may need to be calibrated after being stored for an extended period. A prompt will appear in DJI Fly and calibration will be performed automatically.

Note: During regular flight processes, the vision system of the aircraft is automatically calibrated.

Could you provide us the footage of the prompt if it still prompting and preventing you to fly the aircraft.

We are looking forward to your response for further assistance. Thank You

Hi there,

Thank You for your inquiry, as we mentioned before if you are facing wavy flight or flight instabilty, please perform the troubleshoot as in thread 14#. You can also check on user manual page 58 DJI Mini 4 Pro - Using the Vision system  as there are details about type of surface or enviroment that the vision system unable to detect.

If you've gone through the troubleshooting steps and the issue persists, it could be due to a faulty sensor in the aircraft. To confirm this and ensure a proper assessment, we recommend submitting a repair request.

I hope this information has helped to clarify your inquiries. If you have any questions, kindly let us know. Thank You!

Hi DJI Gamora, this is an inherent flaw in the obstacle avoidance software in the Mini 4 Pro drones. Its not a faulty sensor, its not a single drone doing this, its all of them. Most people just never pay attention and don't notice. Read through the many many posts on this subject throughout the forum and you will find that there are many written accounts, several videos displaying the wavy flight posted, and that several people have sent their drones into DJI for repair, only to have them return certified as functioning properly, and the the flight behavior remains unchanged.
After doing more investigation than I cared to, this wavy flight behavior only happens for me when the collision avoidance is turned on. The wavy flight behavior is in fact the drone rapidly and repeately accelerating and then slamming on the brakes, which creates a wavy flight in the air as the drone changes flight attitude. Turn off the collision avoidance and the flight behavior in question stops immediately, and the drones flight behavior changes to smooth flight. The other characteristic of the flight issue is with the collision avoidance on, the drone will slow greatly in a fast turn, and then accelerate again once it comes out of the turn with the same continuous stick input. With the collision avoidance off, the drone with fly rapidly through a fast turn as it should with the same continuous stick input. Wind also plays a part as turbulent air increases the oscillation.
What this adds up to in my opinion is either some kind of software conflict occuring, or the processing power is simply taxed beyond its limits with the collision avoidance engaged, and is slowing the drone down to ensure safe flight. As more and more features have been added to the Mini 4 Pro through firmware updates, vision sensor camera ability, remote ID, etc, its just gone past its design limits in terms of what the processor and ram can handle all at once. Just an opinion.... and not being negative, just information given in the spirit of DJI finding a solution.  And no I'm not sending my drone in, I bought it to fly, not ship back and forth to DJI in the mail

I have both problems here. The left rear obstacle sensor is misaligned. It misaligned itself, the drone never crashed. This sensor partially shows the rear left propeller.

I don't know if the problems are connected, but I also noticed the wavy motion flight. I didn't know that turning off the sensors would stop it from doing this, but wouldn't the alignment be the cause of this?
The right rear sensor does not film the propeller.

Hello.. SAME issues.. has anyone came up with a solution for the Calibration of the Mini 4 pro vision sensors??? Why can we do this with EVERY other drone besides the MINI 4 PRO??

interesting Gustavo Duarte, I never use the camera view through the vision sensors so haven't looked to check if the prop is in view, I feel its a somewhat gimmicky feature, but to each his own. What I can tell you is my buddy Mike and I bought our drones at the same time, right after they were released, and he's only done the original update when he activated the drone, so has none of the firmware allowing the vision sensor camera feature and his drone also porpoises through the air.

Position your Mini 4 Pro 30 meters up in the air hovering where its clear of any obstacles. First fly with your collision avoidance turned on in the menu, do a circuit flying in the shape of an infinity symbol at full throttle in normal mode and observe the drones behavior. Stop and hover at 30 meters up and turn your collision avoidance off in the menu. Repeat the infinity symbol circuit at full throttle with the collision avoidance turned off and observe the behavior. If you do this where there is no background noise, you'll hear the difference immediately.

Same issue here. Recently i got a minor crash with my Mini 4 Pro and my one of front sensors got stratched a bit. I mean glass of sensor had little fracture. Sensor works well when drone sees a real obstacle. But, in high altitudes like flying over 100 meters or 50 meters doens't matter, sometimes sensors see obstacles that don't exist actually and give me warn of obstacle. In Aliexpress i found a DJI repair seller selling these sensors individually. I don't know how to calibrate them after mounting them to drone. Official DJI vision sensor calibration software currently doesn't support Mini 4 Pro. How can i calibrate new mounted sensor. Thanks..

The Mini 4 Pro sensor i saw on Aliexpress:

Hello mate, did you try to replace the sensor? Today my drone fell down because of some branches and one of the sensors is scratched. Even at high elevation, sometimes the vision sensor keep showing a red line where there is no obscacle at all.

I guess the scratches on the lens is the reason why...

I also found this sensor on Aliexpress and I was wondering if we can replace it without doing any calibration. From what I read here, the Mini Pro 4 can self-calibrate?

I definitely won't be taking it to the DJI after-sales service just for a such minor issue.

Thanks.

My mini 4 pro has had replacement sensors above and below so it’s asking me to calibrate them all and refuses to takeoff until they are done. Is the application working yet for the mini 4 pro to use like the mini 3 pro can use it? If not what do I use to get the sensors calibrated and be able to use my drone again, otherwise it’s just a ornament on the shelf looking out of the window with a very sad face crying all the day

Replacing sensors requires mandatory calibration and programming of sensors in the drone's motherboard. This procedure can only be performed at a service center, there are no other options.

A workaround is to remove the lens from the new sensor and replace it with the faulty sensor. Then there will be no need to program it into the motherboard.

I just replaced the right front sensor and actually, now I can't take off: "Right sensor calibration error". So yes, the sensors have to be calibrated. So now I have to put back the old one which is scratched   BTW it is not easy to replace because they are glued. Any info is welcome to fix this issue as I think DJI Assistant 2 won't be updated anymore. Last update was in 2019.....

How do you view using the sensors?

It seems, situation is still hopeless. The only solution is to take the drone to the service for now. That is what DJI wants from users, not self-repairing like Apple does. For little sensor stratch you will pay high amount of money.. Shame
