Claim 1:
2. The battery winding method according to claim 1, wherein the conversion matrix is preset in a process that comprises:
selecting a reference battery, and photographing each of the winding layers of the reference battery by the photographing module, wherein the same as the picture of the current winding layer obtained at the photographing step, the picture of each of the winding layers of the reference battery also comprises a first area and a second area;
acquiring position data of a first point in the first area and position data of a second point in the second area according the picture of each of the winding layers oldie reference battery, just like the position data acquiring step;
measuring an actual distance of displacement between the first electrode plate and the second electrode plate in each of the winding layer, and correcting the second point based on the actual distance of displacement to obtain corrected position data of a corrected second point;
setting a to-be-calculated conversion matrix comprising to-be-calculated parameters for each of the winding layers, and establishing a relation of correspondence between the position data of the first point and the corrected position data of the corrected second point based on the to-be-calculated matrix; and
selecting, according to the number of the to-be-calculated parameters in the to-be-calculated conversion matrix, a corresponding number of points including the first point in the first area and a corresponding number of points including the corrected second point, corresponding to the points in the first area, in the second area, and importing the selected points into the relation to calculate the parameters of the conversion matrix to obtain the conversion matrix.
