Through threshold transforming, dilation and area labeling of the source image which, input into computer by scanner, contains the information of the whole spinneret, the system can compute locations of every micro - hole. then the pickup camera equipped with microscope is moved on every micro - hole driven by step - by - step motors. the image of the micro - hole is captured to the computer after auto - focusing
該系統經過對掃描儀掃入的整塊的噴絲板圖像進行閾值處理、圖像膨脹、區域標記等圖像處理的手段分析出各個微孔的分佈情況,然後用步進電機驅動加有高倍顯微鏡的攝像頭自動搜尋到每個微孔,對微孔自動的聚好焦后,採集微孔圖像。In view of the altitude problems of inspecting the weighted average ways of obtaining altitude and the advantages and disadvantages of moving surface interpolation method are talked about through comparison, with which the writer draws a conclusion that moving surface interpolation method is suitable to be applied for the dynamic state inspection places, moreover the key technology about the dynamic slate inspection is also taken into consideration, which includes digital camera and types of camera lens, the cause of camera lens distortion and the fundamental determining principle, the gain of image coordinate and the realization of time synchronization
針對檢定點高程問題,分析比較了獲取高程的加權平均法和移動曲而內插法的優缺點,得出移動曲面內插法適合用於動態檢定場的結論。特別是針對動態檢定的關鍵技術給予了相關研究,內容涉及:數碼相機及相機鏡頭的選型,相機畸變差產生原因及測定的基本原理,像片坐標獲取以及時間同步實現,得出結論:利用gpsoem板的秒脈沖( 1pps )輸出特性,能夠實現兩臺數碼相機與gps接收機時間同步,滿足動態檢定指標要求。But for some special medium materials, such as liquid crystal display controller pcb, magnifiers must be used to gather images to gain enough precision of inspection for the weak contrast between the basic board and the conductor. the images near the light axes are much cleared than that far away from the light axes, so the images can not be simply segmented by black and white and inspected with the methods of pcb which are based on the black white image
但對於一些特殊介質材料,如液晶顯示控制電路板的檢測,由於基板和導體之間對比度不大,而且為了達到檢測精度,必須採用放大鏡頭進行圖像採集,成像系統光軸附近的圖像成像質量較好,而偏離光軸較遠的圖像質量較差。不能通過簡單二值化來很好地分割圖像,而已有的印刷電路板檢測方法都是建立在二值圖像進行分析的基礎上。Targets made of ship - building steel, which is concerned, were penetrated by conical and flat - ended projectiles. the damage and failure behaviors of targets have been studied systematically by micro - hardness, metallography and scanning electron micrography. the results show that the ductile hole failures and back - surface petal failures are achieved when targets penetrated by the conical projectiles
本文以某船用鋼為研究對象,運用彈板侵徹試驗及顯微硬度、金相顯微鏡和sem等分析測試手段,研究了靶材在侵徹過程的物理變化和損傷規律,從而對尖頭彈和鈍頭彈侵徹船體鋼的物理過程有了較全面的了解。Computer vision inspection techniques involving ccd camera, lens, lighting and vision software design techniques are discussed in this paper. the techniques are combined with the virtual instrument techniques in our study. two computer vision industry inspection systems are developed, one is used to measuring geometry size, the other is used to inspecting pcba
本課題對計算機視覺檢測技術所涉及的ccd攝像頭、光學鏡頭、照明光源進行了分析和研究;另外,結合實際把邊緣檢測和模板匹配等數字圖像處理技術應用到幾何尺寸檢測和電路板組件檢測當中。分享友人
