Abstract

The invention discloses a method for identifying test paper, which comprises the steps of acquiring a color test paper image in a 24-bit bitmap format; compressing the color test paper image in the 24-bit bitmap format into a color test paper image in an 8-bit bitmap format; carrying out binarization processing on the color test paper image in the 8-bit bitmap format; acquiring a monochrome test paper image; introducing a test paper template; matching the monochrome test paper image with the test paper template; and extracting test paper information included in the monochrome test paper image. The invention further discloses a device for identifying the test paper, which comprises an image acquisition module, an image processing module, a template introducing module, an image matching module and an image information extracting module. The method and the device provided by the invention for identifying the test paper can identify the test paper accurately and effectively and obtain an accurate score of the test paper.

Description

Technical field [0001] The invention relates to the technical field of information recognition, in particular to a test paper recognition method and device. Background technique [0002] With the rapid development of information technology, the combination of test paper review and information processing technology makes it possible to review test papers easily and quickly, which will save a lot of time for the reviewer without consuming too much energy, and it can also effectively shorten the marking time . However, in the existing test paper recognition technology, there are often test paper recognition errors. How to accurately and effectively identify the test paper to obtain the correct test paper score is the primary problem that needs to be solved at present. Summary of the invention [0003] In view of this, the purpose of the present invention is to provide a test paper recognition method and device, which can accurately and effectively identify test papers and obtain cor...
