Abstract

The invention relates to an automatic paper marking image identification system. According to the system, a test paper is shot or scanned through an electronic terminal to form an image document; noise removal, inclination rectification and page analysis of the image document are carried out through an image processing server to generate a machine-readable document and an artificial paper marking document; text of the machine-readable document is cut, combined and identified by a machine-readable processing module and is then compared with pre-stored standard answers to acquire a machine-readable scoring score; an artificial paper marking processing module is made to receive the artificial paper marking document outputted by the image processing server, respond to input of a paper marking teacher and store an artificial scoring score; a paper marking result push module is made to carry out addition of the received machine-readable scoring score outputted by the machine-readable processing module and the received artificial scoring score outputted by the artificial paper marking processing module to acquire a total scoring score, and thereby the test paper in a common mode can be rapidly and accurately identified.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an automatic marking image recognition method and system. Background technique [0002] Traditionally, the examination papers are marked manually. When there are a large number of examination papers to be reviewed, the efficiency of the manual method not only becomes very low, but also prone to errors, which affects the evaluation results of the examination. Therefore, the online marking system for the examination papers in the form of answer sheets has emerged, which realizes automatic scoring through electronic scanning and image recognition technology, which greatly improves the efficiency of marking papers and reduces human misjudgments. [0003] However, in most cases, examinees use test papers in common form. In the prior art, it takes a long time to extract the character features in test papers in common form, which cannot meet the requirements of rapid recogniti...
