Patent number: 11978189Abstract: Embodiments of this application provide a defect detection method and apparatus. The method includes: obtaining an image for inspection; performing anomaly detection on the image for inspection to obtain an anomaly region image corresponding to the image for inspection; and performing defect classification on the anomaly region image to obtain defect detection information of the image for inspection. The defect detection method of the embodiments of this application is divided into two steps of anomaly detection and defect classification. Anomaly detection is performed on the image for inspection first, and then defect classification needs to be performed only on an anomaly region, reducing the workload of defect classification, thereby improving the efficiency of defect detection.Type: GrantFiled: March 31, 2023Date of Patent: May 7, 2024Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Guannan Jiang, Annan Shu, Qiangwei Huang

Publication number: 20240095902Abstract: A tab bending detection method and apparatus, an electronic device, and a storage medium are provided. The method includes: performing skeleton extraction on a sectional image of multiple layers of tabs to obtain a skeleton image of the multiple layers of tabs; merging damaged connected components in the skeleton image to obtain a merged connected component, where the damaged connected components are connected components on which breaking occurs in a same tab section; calculating a target number of the multiple layers of tabs based on the merged connected component and an undamaged connected component; and detecting, based on the target number and a preset number, whether any tab in the multiple layers of tabs is in a bending state. The damaged connected components are merged to obtain the merged connected component.Type: ApplicationFiled: April 25, 2023Publication date: March 21, 2024Applicant: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Qiangwei HUANG, Guannan JIANG, Zhiyu WANG
