A Method for Detecting the Defects of Automotive Brake Friction Plates Based on Grayscale Image Binarization
Due to the low positive detection rate of traditional methods in the detection of automotive brake friction plate defects,the expected detection effect cannot be achieved.Therefore,a method for detecting auto-motive brake friction plate defects based on grayscale image binarization is proposed.The image information of the friction plate is collected using a CCD industrial camera.By binarizing the grayscale image of the friction plate,the foreground area of the friction plate image is extracted.The connected domain of the friction plate con-tour is calculated using an increasing function,and the incomplete features of the friction plate are extracted,thereby identifying and detecting the defect of the friction plate.Through experiments,it has been proven that the design method has a positive detection rate of over 95%,and has good application prospects in the detection of incomplete friction plates in automotive brakes.
