Hi everyone, hope you are doing well.
I only have a question about the metadata of a picture taken by a DJI drone. So when viewing the XMP Metadata, there are two types of Yaw, Roll, and Pitch (the angles around the three axes), the two types are: Flight & Gimbal. I know that Flight e.g. Yaw will be the angle between North and the direction that the Camera is facing. Meaning, if FlightYaw is -90 degrees (and we are perfectly horizontal), I know then that the drone is pointing towards West, if FlightYaw is +90, then the drone is pointing towards East (negative values mean left of North, please let me know if I am incorrect for this assumption).
So now what I don't understand is exactly what angle does Gimbal measure? I initially thought it was the same as Flight, meaning Gimbal Yaw also measures angle between North and where the camera is pointing, assuming perfectly horizontal Drone and Camera, but I now think that Gimbal is actually Camera direction versus Flight Direction. Is that correct? So for example, if drone and camera perfectly horizontal, and Flight Yaw is +90 (drone faces East) and Gimbal Yaw is also +90 (the camera is 90 degrees right of direction of drone), then the direction that the camera is facing (and the picture is taken) must +90 +90 = 180 degrees from North which is South. Is all this math correct or have I made a wrong assumption?
Thank you for your help & time in advance,
Andreas
