Method and apparatus for detecting defect on insulation coating on battery electrode plate, and computer device

A method for detecting a defect on an insulation coating disposed on a battery electrode plate, comprising:

• obtaining an electrode plate image by photographing an electrode plate, wherein the electrode plate image comprises at least one complete electrode plate;
• determining an insulation coating region and a tab region in the electrode plate image;
• determining a defect detection region in the insulation coating region in the electrode plate image based on the insulation coating region and the tab region;
• and
• performing defect detection on the defect detection region to obtain a defect detection result;
• wherein performing the defect detection on the defect detection region to obtain the defect detection result comprises:
• performing a connected component extraction on the defect detection region;
• when a connected component similar to a predetermined defect region exists, determining that a defect exists, and the defect detection result comprises defect existence information;
• and
• when the connected component similar to the predetermined defect region does not exist, calculating a coating region misalignment value of the electrode plate, and the defect detection result comprises defect non-existence information and the coating region misalignment value.
