Why is the aircraft's attitude not considered?

[angaio]

In the code def get_metadata(input_file), only the gimbal's attitude is being read and used, and the aircraft's attitude is not being read or used. Why is that?

Hi angaio

Orientation of a camera from a ground is needed to generate an orthophoto, not orientation of an aircraft itself

But we can only know the orientation an aircraft, we have to convert to the one of a camera

But it is hard to convert orientation from an aircraft to a ground because each has 3-axis, which means it causes gimbal lock

The gimbal(especially in DJI) fix the roll(xy plane) it is easy to convert orientation because the fixed roll makes the conversion of 2D coordinate system

So I used only orientation of a gimbal, it removes 1D in orientation
