| Abstract: | The purpose of PCB automatic online inspection is realized by providing a kind of design of PCB defect inspection based on image-processing. The hardware and software structures of system was built and hybrid inspection algorithm was developed which integrated some efficient measures such as image processing in block, Threshold Segmentation Of Minimum Value. Fast Template Matching and Mor-phological processing. The result of experiment indicated that this method resolved the conflict between datas and time, as well as the disturb of noise, detected the general defect of PCB, and realized the automatic online detecting fast. safely and economically. |
