Hi

I am trying to calibrate the vision system on my P4A, and do step 1, 2 and 3 with success.
BUT, after following on screen commands, restarting aircraft, it keeps goin back to calibrate step 3/3 yet again.
Tried several times - calibrates successfully it sais, but no...

Checked cameras/lenses, screen is found correctly, as well as resolution etc....

Calibration TXT attatched...


Anyone have any idea please?

are you tried in a different surface ?

What do you mean with different surface?
I have tried to different screens, the problem doesent seem to be with them,
i see everything and manage to do the calibration moving it areound (tilting ;) )
but comes back to step 3/3 each time

I mean the surface where the drone is placed

maybe something prevents the calibration from being done correctly

Have to hold the drone to do the vision sensor calibration, in front of the screen with DJI Assistant 2

ohh i see .. i know this part in my Mavic pro ..but i had no problems

dont miss any step , hope it help

Hi, Sorry for the troubles that it caused. I would recommend deleting and re-installing the app.  You can set the screen resolution into default mode before using the Assistant 2 and it would be better if you have a 14-inch monitor or higher than that. Please keep us posted on the latest progress.

Hello , I have the same problem

With recalibration vision system !









I cant even get in to the DJI Assistant ?

Where do I get the verification code from ?
