Greetings all; Do we have such a critter that can analyze the output of a v4l2 camera, and give an amplitude at bandwidth histogram?
I need a way to establish the absolute best focal distance of a camera acting as machine vision, and which acts like about 4 to 5 cm is about right. What I want to do is drive forward until a probe contacts the target, and zero the rest of the visual measurements to that distance for best accuracy. But I'll use this to determine the length of the probe by looking for the highest amplitude at the highest frequencies from zero, which would indicate best focus. Thanks all, for any names of video utils to check out. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
