Missing gimbal angles in JPG file metadata

Beta Feedback
1

I am flying a DJI Mini 3 using Litchi Pilot beta (1.0.0_BETA-dji Build 607).

The following variables are all +0.00 in the JPG file metadata:

drone-dji:GimbalRollDegree=“+0.00”

drone-dji:GimbalYawDegree=“+0.00”

drone-dji:GimbalPitchDegree=“+0.00”

This is not a DJI Mini 3 shortcoming, as images captured using the DJI app have non-zero values for these three variables.

I’m working with SAR software that uses the gimbal values in the metadata to correctly determine the location of objects of interest, so it would be ideal to populate these variables.

Thanks!!

The DJI firmware populates these, not Litchi.

Should only be zero if you take photos before taking off.

Use exiftool -g to show all of the available metadata for different images

Thanks for responding - much appreciated.

I agree they should not be zero, but they are all reported as zero for the Mini 3 during flights; this is not a "before takeoff issue.

I just went and replicated the issue using the DJI fly app, so I think you are correct to say this is a DJI issue and not a Litchi issue.

Have you looked at the complete EXIF/XMP data? There is also:

[XMP] FlightPitchDegree : -3.40
[XMP] FlightRollDegree : -3.40
[XMP] FlightYawDegree : +130.40

FlightYawDegree is a better representation (than GimbalYawDegree) of the yaw at the time a photo is captured.

Would you be able to make one of your files available for me to analyze?

Yes, Flight angles do show up, so the folks behind the SAR software are going to change settings to use that instead of Gimbal data. If you want to play around, here’s an example image. As noted above, this does seem to be an issue with the DJI Mini 3, as the same thing happens when the pics are taken in their Fly app. It is not a Litchi Pilot Beta issue.

I have not seen DJI images missing this data before and I don’t think the correct pitch value is stored in the EXIF data of this file. The photo looks like the pitch value should be around -90. However, the EXIF data shows this:
