Tool Damage Detection Method Based on Improved Threshold Segmentation Algorithm
In order to solve the problem that the current tool wear defects are difficult to be collected by the visual inspection system,an Otsu threshold segmentation algorithm based on particle swarm optimization is proposed.to detect tool wear The algorithm improved update strategy for inertia coefficients which effec-tively expanding the search scope of the algorithm and shortens the running time of the algorithm.By adding a perturbation equation to the particle swarm,solved the problem of traditional particle swarm opti-mization algorithms easily falling into local optima.Finally,an experimental platform is built to verify the effectiveness of the algorithm.This inspection method can achieve the identification of tool damage areas and the measurement of tool damage amount,and has advantages such as high recognition accuracy and fast running speed compared to traditional Otsu algorithm,Canny algorithm,local threshold segmentation and so on.The research results have certain reference value for the actual tool defect detection system.
