| Abstract: | Asynchronous dual-cache method and MATROX frame grabber were used in PCB Appearance Inspection Machine for image acquisition and real-time processing.Because the images collected from PCB visual inspection machine were at high pixels,a method for Image Stitching was proposed based on combination of GDI+ graphics device interface library and ActiveMil library.As a result,the speed of image acquisition was increased by 30% and the development cycle was shorten by using ActiveX assembly. |
