EXIF/XMP Heading information

[MartinKS]

I've written some scripts to process timelapse photos I'm taking into a video, but I've noticed that some of the images aren't facing the right way.
I can't see where camera heading is encoded into the EXIF or XMP portions of the jpg/dng file - does anyone have any experience with this?

I've found the gimbal and flight yaw/pitch/roll - do I have to work with these to do some maths? and if so are they relative to the drone's orientation on takeoff?

The gimbal yaw is the camera heading relative to true north.

Thanks, for anyone coming to this thread later it seems to be encoded in +- degrees to North with -90 being West and +90 East.

Sar, are the gimbal and flight pitches additive or absolute to "level"?

Absolute, i.e. relative to horizontal.
