(9) ,-G:RS TUABVW XY1 . Abstract This report uses the visual inspection technique to measure the dimensions of objects on a PCB. First, we will take a brief review for PCB visual inspection techniques. Then introduce how to built a reference data compared with test data, and the algorithm we use in our inspection system, called "Dimensional Verification". At last, we domostrate the whole inspection flow by taking a real example on PCB.. .
