摘要：
The present application provides an appearance detection method and apparatus for a bare cell, a computer device, a computer-readable storage medium, a computer program product, and an appearance detection system for a bare cell, where the method includes: obtaining a cell picture of the bare cell by shooting, the cell picture being obtained by shooting in alignment with positions of tabs on an edge of the bare cell; determining a detection object in the cell picture; and performing appearance detection based on the detection object to obtain detection result information. The cell picture is obtained by shooting in alignment with the positions of the tabs on the edge of the bare cell, such that imaging of cell edges is parallel light reflection imaging, which reduces an impact of a thickness of the cell on the edge authenticity of the tabs of the cell, and ensures the accuracy of image acquisition, thereby improving the accuracy of appearance detection of the bare cell.
