Claim 3:
4. The battery winding method according to claim 1, wherein at the convening, the conversion matrix Fi is used to establish a formula (2) which converts the position data of the first point into the converted position data of the converted first point,

PTFiQ=0  (2),

wherein, P represents the position data (xP,yP,1) of the first point in the picture of the current winding layer photographed at the photographing, xP is a coordinate in the first direction, yP is a coordinate of the first point in the second direction perpendicular to the first direction in the picture of the current winding layer photographed at the photographing step, and PT is transposition of P;
Q represents the converted position data (xQ,yQ,1) of the first point in the picture of the current winding layer photographed at the photographing, xQ is a coordinate of the second point in the first direction in the picture of the current winding layer Photographed at the photographing, and yQ is a to-be-calculated coordinate in the second direction;
the conversion matrix Fi is, [

  ,, comprising eight parameters, A11, A12, A13, A21, A22, A23, A31 and A32, representing a relation of converting P into Q in the ith winding layer;
i represents the number of winding layers; and
xP, yP, XQ and Fi are imported into PTFiQ=0 to calculate yQ;
in the picture of the current winding layer photographed at the photographing, a coordinate in the second direction, in the position data of the second point is selected and defined as yR; and
a difference between yQ and yR is calculated to obtain data of displacement between the first electrode plate and the second electrode plate.
