Research And Design Of Wire Harness Detector Based On Color Recognition

With the development of modern Chinese,more and more large scale harness industry,as well as the automotive,aerospace,medical equipment and other fields will use wire harness,,at the same time,it is also faced with a variety of bad wiring harness,such as different color lines are not in the corresponding position and wrong wiring,etc;The traditional detection mainly depends on human identification,but the artificial identification will increase the unreliable factors,It is easy to cause all kinds of mistakes(such as wrong check,missed check,etc.),so that the unqualified rate of wire harness products is greatly increased.Therefore,this paper designs a set of wire harness detection system,for the detection of a variety of single row wiring harness products,which not only has a good accuracy and unity,but also anti noise interference,Thus,the detection performance of the wire harness detector is improved.In order to design a detection and identification method,I was carefully studied the specific characteristics of the test object and related production processes and other requirements.The components of the harness detector are designed and demonstrated,and focusing on the image processing and image recognition two aspects of research and design.In this paper,the design of the wiring harness detector is mainly based on the machine vision,machine vision instead of the human eye on the color wiring harness for accurate detection and identification,it built on the basis of the system hardware,the application of the Microsoft virtual instrument software Visual C ++ 6.0 and visual processing tools Open CV as a development platform.Firstly the image is collected by the camera,then the related harness image is pre-processed to enhance the quality of the image and eliminate the external disturbance and noise.Then the color harness image information is extracted by delineating the ROI region;Finally detection algorithm and color harness color recognition algorithm for a variety of color wiring harness to accurately detect and identify.Finally,the continuous improvement and debugging of the detection system,the system can not only quickly identify the color of different lines in accordance with a certain order to insert the corresponding hole,and can accurately display the location of bad line order,and the display output is displayed in the detection screen,which proves the feasibility and practicability and reliability of the harness detector designed in this paper.
