  "textContent": "A deviation detection method and a deviation detection device for detecting positional deviation of an electrode assembly during winding are provided. The method comprises: obtaining a plurality of first images and a plurality of second images by using a photographing unit during the winding process of the electrode assembly, where the first image includes a first electrode sheet, and the second image includes a second electrode sheet; matching a first image with a second image, where the first image and the second image contain the same or corresponding identification objects, and the identification objects are portions periodically formed on each winding layer of the electrode assembly; and determining whether the electrode assembly is deviated according to the boundary of the first electrode sheet in the first image and/or the boundary of the second electrode sheet in the second image in a group of matching first and second images.",
