Examination paper analysis method and calculation equipment

Abstract

The invention discloses an examination paper analysis method which is suitable for being carried out in calculation equipment. The method comprises the following steps: obtaining an image of examination paper to be analyzed, and identifying connected domains of various characters in the image; carrying out text line divisions on the examination paper according to identified connected domains of the various characters, and carrying out character content identification on the connected domains of the various characters; according to identified character content, selecting a text line, which takes a topic number as the beginning, from divided text lines as a topic beginning text line, and determining the topic area of each topic according to the position of each topic beginning text line; extracting color components of teacher checking handwriting from examination paper images, and identifying the color components to obtain teacher checking information; and enabling the teacher checking information to be corresponding to a corresponding topic area and the topic number so as to determine the teacher checking information of each topic. The invention discloses corresponding calculation equipment.

Description

technical field [0001] The invention relates to the field of electronic teaching, in particular to a test paper analysis method and computing equipment. Background technique [0002] With the development of computer and Internet technology, people are increasingly using automated equipment to mark student examination papers. The automatic marking method in the prior art usually adopts the ORC recognition system, and usually requires the clarity of the test paper image to meet a certain condition, and it usually can only analyze the test paper with a fixed template, that is, it can only compare the test paper with a number of files that have been stored in the system. A template is matched, and the matched template is used for analysis. [0003] However, in actual operation, people sometimes hope to obtain test paper images by taking photos with their mobile phones. In this case, problems such as low image resolution, uneven lighting, tilted photos, and blurred imaging may o...

Problems solved by technology

[0003] However, in actual operation, people sometimes hope to obtain test paper images by taking photos with their mobile phones. In this case, problems such as low image resolution, uneven lighting, tilted photos, and blurred imaging may occur.

These complex imaging conditions will undoubtedly increase the difficulty of test paper analysis, and the layout and types of many real test papers do not necessarily match the fixed templates. Therefore, it is necessary to provide a solution that can accurately identify and automatically analyze test paper images to meet People's increasing electronic marking requirements
