Re: What information can we access from the camera?

This is precisely what I (and others) hope teams will do this year. I'm writing a one page white paper on computing range, which I'll post soon. Basically, range = (green light height - camera height)/tan(tilt angle), where green light height equals 10' 10", camera height is the distance the camera is mounted above the floor and tilt angle is the calculated tilt angle derived from the tilt PWM value when the tracking software has a good solution. I've posted the camera software Dave Lavery mentioned here: http://kevin.org/frc
