Abstract

The invention discloses a method and a system for automatically indicating the correctness of a homework exercise. The method comprises the following steps: acquiring a to-be-judged image of a homework book or test paper to be corrected in a color reference line frame; comparing the to-be-judged image with a standard exercise set to find out a standard exercise image with a highest matching degree, wherein each standard exercise image comprises standard answer characters, positions and sizes of each small question answering block; obtaining a small question answering sub-image of each small question answering block in the to-be-judged image, identifying answering characters from small question answering sub-images through a standard function, comparing the answering characters with standard answer characters of the corresponding small question answering blocks in the standard exercise image, and determining the correctness of an answer of each small question answering block in the to-be-judged image; and according to the projection of the correctness of each small question answering block in the to-be-judged image at the corresponding position on the corresponding exercise book ortest paper, outputting a color right mark or a wrong mark. According to the invention, automatic and high-speed answer correctness indication can be realized.
