A dimension detection method for a battery composite surface includes: acquiring image information of a cathode sheet, the image information including an image of a first surface of the cathode sheet and an image of a second surface opposite to the first surface; acquiring image information of a composite sheet which includes a non-composite surface and a composite surface, the non-composite surface being formed by compounding the first surface of the cathode sheet, an anode, and a separator, the composite surface being formed by compounding the second surface of the cathode sheet, the anode, and the separator, and the image information of the composite sheet including image information of the non-composite surface; and calculating dimension information of the composite surface by an image processing algorithm, according to the image information of the cathode sheet and the image information of the composite sheet.

Method, device, and system for detecting size of battery composite surface

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.
