Camera sight angles measurement #26

Closed pbag47 closed 2 years ago

pbag47 commented 2 years ago

This information could be useful to approximate distances by comparing the ARUCO markers real size with the measured size on the camera frame (neglecting the lens distortion is a brutal approximation, especially near the borders of the screen, but it can still provide a good distance reference between the UAV and the marker in sight). The sight angles (vertical and horizontal) might be different between the simulator and the real Tello camera.

Why accomodate with the lens distortion doing nothing ?

I propose we compute these local distortion based of a picture taken with the Tello of a regular grid
