3 to confirm no soldering defect on pcb
確認電?板的元件是否有浮焊。 -
This dissertation discusses the arithmetic of the image process, shows and explains the pseudocode, illustrates the feasibility and validity of liquid crystal display controller pcb defect inspection adopted image process
本文詳細地論述了圖像處理中的演算法並給出了偽代碼予以說明。對採用圖像處理的方法檢測液晶顯示控制電路板的可行性和有效性進行了闡述。 -
Based on the analysis and conclusion of the existed methods of pcb defect inspection and widely gathered data, the author put forward a solution, in which two parameters - the distance of conductors and the width of conductor can be used to detect the defect of pcb
我們進行了廣泛的資料收集，對已有的印刷電路板檢測方法進行了分析、歸納的的基礎上，提出以導線間距離和導體寬度為為特徵參數來檢測印刷電路板缺陷的方法。 -
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高解析度和大視場之間的矛盾，上下位微機并行系統如何控制印刷電路板圖像自動採集，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，本課題將就如何結合計算機視覺技術、精密機械技術、自動控制技術和圖像處理技術，如何解決圖像採集高解析度與大視場之間的矛盾，如何實現圖像的自動拼接，如何實現兩維工作臺的精確定位，如何實現上下位機的準確通訊，如何檢測線寬、線距缺陷和丟失線條等問題展開重點研究。 -
This paper has confirmed the project of inspecting pcb " s defect automatically with optic photographic technique, computer control technique and image process technique, and has been proved to the a feasible method in the automatic testing of pcb
本課題確定了利用光學攝像技術、微機控制技術、圖像處理分析技術來自動檢測pcb的方法，為pcb的自動檢測提供了一個切實可行的方案。 -
In the condition, other way to inspect the defect of pcb must be found
為此，必須尋找其他的方法來檢測電路板的特徵參數。
