碩士 === 國立交通大學 === 資訊科學與工程研究所 === 102 === Now,people correct the location error of the printed circuit board,the most common way is to use camera to capture the circle or some mark on the printed circuit board. If we find the circle on the printed circuit board, it is necessary to find the circle using the Hough Transform to specify the circle to determine whether the printed circuit board is correctly placed. But let the camera capture full mark on the printed circuit board,we often need to go through repeated adjustment, and then we can capture the full mark. I hope to put multiple camera on the printed circuit board in different blocks, and apply Geometric Hashing to find the desired reference picture blocks to make the image alignment, so you can’t find mark on the print circuit board.
