acquiring a marked-product image obtained by photographing a marked product upon completion of a marking operation on a product;
identifying an identification code image in the marked-product image;
comparing whether the identification code image is consistent with an identification code mark image corresponding to the product to obtain an image consistency comparison result;
performing image identification on the marked-product image to obtain a mark quality identification result of an identification code in the marked-product image, the mark quality identification result comprising the image consistency comparison result; and
outputting a first indication signal under a condition that the mark quality identification result is normal, wherein the first indication signal is used to indicate that the marked product flows to a process subsequent to the marking operation.
