Claim 0:
1. A deviation detection method, wherein
it is used to detect positional deviation of an electrode assembly during winding, the electrode assembly comprising a first electrode sheet, a second electrode sheet and a separator,
the deviation detection method includes:
obtaining a first image and a second image using a first camera and a second camera, the first image comprises an image of a first electrode sheet of an electrode assembly during winding, and the second image comprises an image of a second electrode sheet of the electrode assembly during winding;
determining camera deviation, comprising determining whether the first camera and/or the second camera is deviated according to a distance from a reference point in the first image to a specific position and/or a distance from a reference point in the second image to the specific position, the specific position being a position of a same object appearing in the first image and the second image; and
determining electrode assembly deviation, comprising determining whether the electrode assembly is deviated according to a vertical distance from the reference point in the first image to a boundary of the first electrode sheet and a vertical distance from the reference point in the second image to a boundary of the second electrode sheet in response to determining that the first camera and the second camera are not deviated.
