DEFECT DETECTION METHOD AND APPARATUS, AND COMPUTER DEVICE AND COMPUTER-READABLE STORAGE MEDIUM

A defect detection method and apparatus, and a computer device and a computer-readable storage medium. The method comprises: acquiring a template image, and an image to be subjected to detection (S101); on the basis of the template image, and the image to be subjected to detection, generating a mask image corresponding to the image to be subjected to detection, wherein a pixel value of each first pixel point in the mask image represents an anomaly degree value of a defect being present in a second pixel point matching each first pixel point in terms of position, and the second pixel point is a pixel point, which matches the first pixel point in terms of position, in the image to be subjected to detection (S102); and on the basis of the mask image, determining a defect detection result of the image to be subjected to detection (S103). La présente invention concerne un procédé et un appareil de détection de défaut, et un dispositif informatique et un support de stockage lisible par ordinateur. Le procédé consis
