#165443 - TV Tracking |
Hi All,
I have design a vision processor system to find and track position of a crevice when it is exposed to laser beam. In this design a TV cart take video frames from tv camera,and a windows application software processes this frames, after processing the software sends a value to MCU(to drive DAC) to tracking the position, all things are ok when the high voltage motors are off, and closed loop tracking tested perfectly.because when we change the position of crevice far from the center of image and start the process it returns to center again, But as soon as the motors turns on The pc hangs,(mcu never hangs) we changed pc to industrial pc,but the problem did'nt solve, we connect pc chasis to earth of factory where the motors earth were but the problem unchanged, So Can You Please Help Me If you have any experiences about this problem, Thanks in advanced, Mehdi |
