The invention relates to a test paper image processing method and device, a storage medium and electronic equipment. The method comprises the steps of obtaining an original test paper image corresponding to a to-be-processed test paper image; the to-be-processed test paper image is an image obtained after a user answers a test paper corresponding to the original test paper image; acquiring optical flow information between the original test paper image and the test paper image to be processed; performing image alignment on the original test paper image and the test paper image to be processed according to the optical flow information; and obtaining answer information corresponding to the to-be-processed test paper image according to the aligned original test paper image and the to-be-processed test paper image. Therefore, the answer information of the user can be more accurately obtained according to the aligned image, the accuracy of obtaining the answer information is improved, meanwhile, due to the fact that handwritten character recognition is not needed, the answer information can be accurately obtained for the scene that the question and the answer are both handwritten, the application scene of test paper image processing is increased, and the user experience is improved. And the accuracy of obtaining the answer information is improved.
Description
technical field [0001] The present disclosure relates to the field of computers, and in particular, to a test paper image processing method, device, storage medium and electronic device. Background technique [0002] With the development of computer and Internet technology, more and more people use electronic devices to mark students' examination papers. For example, the user can convert the paper version of the test paper information into a test paper image by taking a photo or scan the test paper, and upload the test paper image to an electronic device (such as a server or a terminal device) for marking the test paper image. The test paper image uploaded by the user may include question information and answer information. For example, the question information may be printed on the original test paper, and the answer information may be handwritten by the user based on the original test paper. In order to improve the efficiency of electronic marking, it is necessary to obta...
