Mouse shell surface defect detection method, device and system and electronic equipment

Abstract

The invention discloses a mouse shell surface defect detection method, device and system and electronic equipment, and the method comprises the steps: obtaining an image of a to-be-detected mouse shell, and the image comprises an image of the top of the to-be-detected mouse shell, images of four side surfaces and an image of the bottom of the to-be-detected mouse shell; the image is preprocessed; inputting the preprocessed image into the trained defect detection model to obtain a preliminary detection result; and performing non-maximum suppression operation on the preliminary detection result to obtain a defect detection result. According to the method, the image of the top, the images of the four side faces and the image of the bottom are collected, uneven imaging caused by an irregular curved surface is overcome, and the problem that the imaging effect of surface texture defects is greatly influenced by the lighting direction and the shooting angle is greatly solved; and the preprocessed image is input into the trained defect detection model for defect detection, and the detection accuracy, robustness and efficiency are improved through a deep learning algorithm.
