Abstract

The present invention provides an answer sheet image correction method and device, a readable storage medium and an electronic device. The method comprises: obtaining a template answer card image filecomprising a template answer card image and location frame information, wherein the location frame information comprises sizes of location frames and positions of the location frames in the templateanswer card image, and identifying target content selected by each location frame in the template answer card image; obtaining an answer card image, matching the answer card image and the template answer card image, determining positions of the location frames on the answer card image, and identifying content selected by the location frames on the answer card image; and if content selected by eachlocation frame is not the same as the selected target content by each location frame, sending prompting information to prompt recording of location point position information; and receiving recordedlocation point position information, obtaining positions of special contents, being the same as the target content, on the answer card image according to the location point position information, and realizing location of the answer card image. The correction efficiency is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method, a device, a readable storage medium and an electronic device for correcting a picture of an answer card. Background technique [0002] With the development of science and technology, various large-scale examinations, such as the college entrance examination, English CET-4 and CET-6, all adopt online marking methods, which greatly improves the efficiency of marking large-scale examinations. Usually, online marking is to scan the answer sheet of the examinee into a picture of the answer sheet, and then store it after image processing, so that the marking teacher can retrieve and mark the paper. In the process of image processing, it is necessary to locate the picture of the answer sheet, that is, to compare the picture of the answer sheet with the picture of the standard answer sheet, so that the picture of the answer sheet and the picture of the standard answer sheet can b...
