Abstract
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.
