I am working for 190/360 view cameras.
I am not sure where to get these parameters and what they are meant for.
May I know where do I get for

* top-angle - Top Field of View Angle, in degrees
* bottom-angle - Bottom Field of View Angle, in degrees
* pitch - Viewing parameter Pitch, in degrees
* yaw - Viewing parameter Yaw, in degrees
* roll - Viewing parameter Roll, in degrees

I am referring to the link
I just have camera record from 360 camera.
Where should I look into to get these parameters?

Did this still be an issue? please check the document:
