| With the rapid development of the electronics industry and the extensive application of integrated circuit, requirement of accuracy is increasing day by day in the printed circuit board industry. An embedded positioning punching system based on machine vision is described. The system adopts the fast Hough transform algorithm to seek out the center location, used S3C6410 as the master chip for acquisition and processing the CCD image, and drove the stepping motor for positioning and punching. Testing results show that the performance of the system can perfectly meet the expected target. |
