Abstract: This application provides a displacement detection method for anode composite strip. The anode composite strip includes an anode plate and a separator attached to a surface of the anode plate, where the anode plate includes positioning holes. The displacement detection method includes: step S1000: obtaining an image of a portion of the anode composite strip including the positioning holes; and step S2000: calculating a displacement characteristic quantity based on the image, where the displacement characteristic quantity includes any one or any combination of a width direction displacement, a strip movement direction displacement, and a displacement angle.

Abstract: The present application relates to a camera calibration method and apparatus, a computer device, a storage medium, and a program product. The method includes: obtaining a first operation instruction based on a camera calibration interface; determining, from configuration information, target configuration information matching the first operation instruction and set based on the camera calibration interface; and then executing a corresponding operation in a camera calibration process based on the first operation instruction and the target configuration information. However, the camera calibration process provided by embodiments of the present application is implemented based on the camera calibration interface, without switching back and forth between a plurality of tools, thereby making the camera calibration process less cumbersome.

Abstract: The disclosure discloses a marking method and apparatus of a continuous composite strip. The method incudes: collecting a first sequence of images of the continuous composite strip; splicing multiple images of the first sequence of images according to a collection sequence, to obtain a to-be-detected image with at least one electrode sheet structure; and marking, in case where two electrode sheet edges are identified in the to-be-detected image, a position of the collection-sequentially second electrode sheet edge in the continuous composite strip as an electrode sheet division position of the continuous composite strip. The method determines the electrode sheet division position by identifying the electrode sheet edges in the continuous composite strip, obtains the specific position information of the electrode sheet, and accurately performs the sheet division marking of the continuous composite strip.
