| Abstract: | A PCB circuit detection system was designed based on the technology of image process- ing. Modules of image pre-processing, threshold segmentation, morphological filtering and defects recognition were realized by Labview. In accordance with PCB image speciality and the characteris- tics of the PCB circuit line, the PCB circuit detection system can detect and analyse short circuit, open circuit, concavity and protuberance. The experimental results show that the algorithm of the detection system is simple with application prospects. |
