Abstract: Provided are a battery winding method, a battery winding system, a battery and an electrical device. The battery winding method includes: winding; photographing a picture of a current winding layer; acquiring position data of a first point and of a second point according to the picture of the current winding layer, converting the position data of the first point to obtain the converted position data of a converted first point using a preset conversion matrix corresponding to the current winding layer based on the number of the current winding layers and calculating data of displacement between the first and second electrode plates based on the converted position data of the converted first point and the position data of the second point, and determining if the data of displacement is within a threshold value scope, if so, returning to wind a next winding layer, and if not, sending an alarm.

Abstract: An image acquisition apparatus includes a camera, a first light source, a second light source, and a lens. The first light source is configured to emit first light toward one electrode plate so as to illuminate a local portion of the electrode plate, and the first light source emits the first light at an angle such that the first light is able to be reflected to the camera via the electrode plate. The second light source is configured to emit second light toward the other electrode plate so as to illuminate a local portion of the other electrode plate. The lens includes a reflective region, where the reflective region is arranged at an angle to reflect the second light reflected by the second electrode plate to the camera, such that the camera acquires a stitched image of the positive and negative electrode plates.
