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,還有ccd高分辨率和大視場之間的矛盾,上下位微機(jī)并行系統(tǒng)如何控制印刷電路板圖像自動(dòng)采集,印刷電路板的線寬、線距和丟失線條等缺陷如何檢測等問題還懸而未決,本課題將就如何結(jié)合計(jì)算機(jī)視覺技術(shù)、精密機(jī)械技術(shù)、自動(dòng)控制技術(shù)和圖像處理技術(shù),如何解決圖像采集高分辨率與大視場之間的矛盾,如何實(shí)現(xiàn)圖像的自動(dòng)拼接,如何實(shí)現(xiàn)兩維工作臺(tái)的精確定位,如何實(shí)現(xiàn)上下位機(jī)的準(zhǔn)確通訊,如何檢測線寬、線距缺陷和丟失線條等問題展開重點(diǎn)研究。
