Except that , many problem can " t be solved , such as the conflict of ccd " s high resolving power and big vision field , how to control the automatic gathering of pcb " s image using master and slave computer parallel structure , how to inspect the defect of pcb such as width of circuit , distance of circuit , losing circuit and so on . the research aim at how to combine computer vision , precise machine , automatic control with image process , at how to resolve the contradiction between high resolving power of image gathering and wide vision field , at how to realize automatic mosaic of image , at how to realize precise orientation of two dimension worktable , at how to realize communication between master computer and slave computer , and at how to inspect the defect of line width , line distance and losing 除此以外，还有ccd高分辨率和大视场之间的矛盾，上下位微机并行系统如何控制印刷电路板图像自动采集，印刷电路板的线宽、线距和丢失线条等缺陷如何检测等问题还悬而未决，本课题将就如何结合计算机视觉技术、精密机械技术、自动控制技术和图像处理技术，如何解决图像采集高分辨率与大视场之间的矛盾，如何实现图像的自动拼接，如何实现两维工作台的精确定位，如何实现上下位机的准确通讯，如何检测线宽、线距缺陷和丢失线条等问题展开重点研究。
