Deviation rectifying method and device for battery cell, deviation rectifying control equipment and deviation rectifying system

The embodiment of the invention provides a deviation rectifying method and device for a battery cell, deviation rectifying control equipment and a deviation rectifying system. The method comprises thefollowing steps that: a plurality of detection images obtained by respectively performing image acquisition on the battery cell in a winding process by a plurality of pieces of image acquisition equipment under respective fixed visual fields are acquired; according to the plurality of detection images, a plurality of first distance parameters/a plurality of second distance parameters between thefirst edge/the second edge of each layer to which detection objects of the battery cell are wound and the first reference line/the second reference line of the detection objects of the battery cell are obtained, wherein the detection objects comprise an anode plate, a cathode plate or a diaphragm; the edge change parameters of the detection objects are calculated when the data volume satisfying afirst floating range/a seco
