Abstract

Embodiments of the present disclosure provide a detection method and apparatus, an electronic device, and a storage medium. In one form, the detection method includes: providing a layout graphic and a scan graphic; superimposing and comparing the layout graphic and the scan graphic, and extracting a sample non-overlapping pattern; encoding the sample non-overlapping pattern, to form sample coded data; using the sample coded data as input data of machine learning, to obtain a detection model library; and detecting a defect point of a to-be-detected device by using the detection model library. The present disclosure can improve the accuracy of defect point analysis, thereby accelerating the development of technology and improving the production efficiency.
