Method for intelligently marking paper with trace left based on 8-character code

Abstract

The invention discloses a method for intelligently marking paper with trace left based on an 8-character code. The method includes the following steps: marking paper; manually giving score for subjective questions; scanning the paper; conducting OMR identification on the objective questions, conducting OCR identification on the subjective questions; after conducting OMR identification on the objective questions, successively conducting filling point positioning, light emitting processing, analyzing and mark processing; after conducting the OCR identification on the subjective questions, successively conducting image identification, image pre-processing, text cutting, feature extraction, single component identification, word post-processing, and character proofreading; and counting the scores of the objective questions and subjective questions. According to the invention, the method, on the basis of OMR optical mark identification technology, innovatively applies the OCR optical character identification technology, and converts scoring mark of a teacher to a corresponding computer value in an accurate manner, so that the method effectively saves marking traces of the teacher while conventional online paper marking systems can not. According to the invention, the method can leave trace during paper marking, can effectively avoid repetitive work for the teacher, and increase the quality of paper marking.

Description

technical field [0001] The invention belongs to the technical field of education system processing, and in particular relates to an intelligent mark marking method based on 8-character codes. Background technique [0002] With the development of computer network technology, high-speed scanning technology and graphic image technology, the traditional manual marking and answer sheet cursor scanning marking mode is gradually replaced by the online marking mode. The online marking system is an online application designed according to the marking mode of large-scale examinations such as high school entrance examination and college entrance examination. It not only enables junior and high school students to be familiar with the answering standards of large-scale examinations, but also fully meets the statistical analysis and evaluation functions required by educational measurement. In addition, the online marking system has the characteristics of less investment in construction an...
