Test paper correction method and device, storage medium and electronic equipment

The invention relates to a test paper correction method and device, a storage medium and electronic equipment, and the method comprises the steps of obtaining an original image of a to-be-corrected test paper, wherein the original image comprises a background region image and a test paper region image of the to-be-corrected test paper; inputting the original image into an edge detection model obtained through pre-training, obtaining edge feature points corresponding to multiple scales, wherein the model structure of the edge detection model comprises a backbone network and side edge networks connected with the backbone network; and for the edge feature points corresponding to the scales, removing non-target edge feature points in the edge feature points of the scale by adopting a non-maximum suppression algorithm to obtain target edge feature points of the scale; determining an edge feature image of the test paper to be corrected according to the target edge feature points respectively corresponding to the pl
