Abstract A new detection method and its equipment for defects of toughened glass insulators are described.The statistical law of distribution of glass insulator defects and bands of scattered light are analyzed.Based on machine vision technology,a large area ring LED light source is used in the rotary control platform.Canny operator image segmentation and neural network technology are presented in this research in order to overcome the difficulties in defect detections caused by complex shapes of toughened glass insulators and diversity of the defects.The experiment shows this method and equipment can meet the needs of industrial automation production.
