1. A method of marking a continuous composite strip, the method comprising:
collecting a first sequence of images of the continuous composite strip;
splicing multiple images of the first sequence of images according to a collection sequence, to obtain a to-be-detected image with at least one electrode sheet structure;
marking, in case where a first electrode sheet edge and a second electrode sheet edge along the collection sequence are identified in the to-be-detected image, a position of the second electrode sheet edge in the continuous composite strip as an electrode sheet division position of the continuous composite strip;
determining an edge spacing between the first electrode sheet edge and the second electrode sheet edge according to collection sequence and the electrode sheet division position; and
outputting an image of an electrode sheet unit comprising one of the at least one electrode sheet structure, in case where the edge spacing meets a spacing requirement of electrode sheet division of the continuous composite strip.
