Abstract: Provided are 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.

Abstract: Provided are a detection method, an electronic device, and a computer-readable storage medium. The detection method includes: receiving an image of a product to be detected, and detecting a position of a preset feature point on a cover plate based on the image, where the product to be detected includes a connection piece and a cover plate, the connection piece is located on the cover plate and covers a partial region of the cover plate, and the preset feature point is located in a non-edge region on the cover plate that is not covered by the connection piece; obtaining a position of the cover plate in the image based on the position of the preset feature point and a size of the cover plate; and obtaining a position of the connection piece in the image based on the image.
