Here's the equation:
FOV = 180/PI * 2 * atan( frame_size / (2*focalLength) )
where frame_size is 36mm and focalLength can be obtained using the focalLengthAtTime method.

Regarding the Fx3DAPI protocol :
I get strange values for the Field of view of Motion camera.
ex :
in motion with a framing camera :
a FOV of 1° output 2062.59570232
a FOV of 90° output 18
a FOV of 180° output 0,25134374
what is the logic with those numbers ?
Best regards.
