為了解決電線束組裝之瑕疵檢驗問題，本論文開發出針對電線束之零組件進行裝配檢測、定位檢測與尺寸量測等之自動化光學檢測系統。本研究使用單一攝影機進行實驗。利用影像之平均灰階值對電線束之標籤進行裝配檢測。使用模板匹配法對電線束裝配件之束帶、端子與車輪零件等進行裝配檢測與定位檢測。再使用邊緣偵測法對電線束之支線及全長與標籤進行尺寸量測與定位檢測。最後對十條電線束產品進行機器視覺瑕疵檢測，同時以人工目視檢測的結果作為參考，與本研究所開發的影像檢測系統之檢測結果進行比較，以此得知兩個檢測方法的差異。本研究所開發之影像系統對其中八條電線束進行瑕疵檢測結果與人工目視檢測結果相符，而有少數幾個長度量測值差異為1 mm。其中對第四條電線束進行瑕疵檢測時，發生標籤定位檢測誤判問題，其原因是邊緣偵測法偵測到電線束上之反光點導致誤判發生。對第七條電線束進行瑕疵檢測時，發生長度量測異常問題，其視覺量測與人工量測相差4 mm，誤判原因是人工安裝電線束時，安裝錯位導致長度量測起始點錯誤而引發誤判。最後將誤判起因修正後，重新對十條電線數進行檢測，其檢測結果皆與人工目視檢測結果相符合。因此本研究所開發的方法，可應用於電線束產品瑕疵檢測。

In order to solve the problem of defect inspection of a wire harness assembly, the objective of the research was to develop an automated optical inspection system for defect detection, component location detection and length measurement of the components of the wire harness.
A CCD camera was used for this research. The label on the wire harness was inspected using the average gray scale value of the image. The template matching method was used for assembly detection and positioning detection on the strap, connector and wheel components on the wire harness. In addition, the edge detection method was used to measure the length and position of the wire branch, the length and the label of the wire harness.
At last, the inspection system was tested using ten wire harness products. The results of visual inspection were used as references and compared with the results of the inspection system developed in this study to learn the difference between the two methods. The detection results of the eight wire harness were the same as the results of visual inspection. The differences in length were about 1 mm.
When the fourth wire harness was tested, a misjudgment of the label positioning detection occurred. The reason was that the edge detection method detected the light reflection point on the wire harness and caused misjudgment. When the seventh wire harness was tested, the incorrect length measurement occurred, and the visual measurement is different from the optical measurement by 4 mm. The reason for the misjudgment was that when the wire harness was manually installed, the misalignment caused the starting point of the length measurement incorrect.
Finally, in the case of the correct installation of the wiring harness, the method developed in this study can be applied to inspect the wire harness product without any problem.
