BATTERY CELL DETECTION METHOD, APPARATUS AND SYSTEM, AND COMPUTER DEVICE AND STORAGE MEDIUM

A cell detection method and apparatus, a system, a computer device, a computer-readable storage medium, a computer program product, and a cell detection system are provided, where the method includes: obtaining, by shooting, a cell picture of a cell obtained after tab welding, the cell picture being shot under illumination of a shadowless light source; determining a detection object in the cell picture; and performing defect detection based on the detection object to obtain detection result information. In this method, the cell picture of the cell obtained after tab welding is shot under illumination of the shadowless light source, which can reduce a risk of false detection due to an impact of light spots caused by slight bending of an adapter plate, thereby improving the accuracy of defect detection on the cell that is obtained after tab welding.
