I have an Intel Aero quadcopter with a rangefinder, gyroscope, and downward-facing optical flow calculator. I can get optical flow values in rad/s, but I need to estimate the x-and-y velocities of the drone using the information I have available.
I was wondering what the best way to do this is -- how do I relate the angular velocity calculated by the optical flow sensor to the actual velocity of the drone through its environment?
