An algorithm was proposed for mechanical dimension inspection of PCB, it is based on position relationship to extract and discern graphic feature .A standard PCB image were selected as the standard drawing , in which creating a template used for image matching and determine the detection area and classification, standard size and tolerance of detection characteristics. Adopting the method of template matching to locate the PCB detection area. According to the classification of the detection characteristic,Adopting the appropriate method to extract and discern graphic feature. comparing to a standard size and tolerance, Determining whether the PCB is qualified. Based on the detection requirements for PCB, fast effective automated detection method is proposed.
