Electronic paper marking method

Abstract

The invention provides an electronic paper marking method. The method comprises the following steps of carrying out gray-scale processing on a test paper image to acquire a grey-scale image corresponding to the test paper image; detecting a characteristic identification in a test paper grey-scale image, and according to the characteristic identification, extracting a content of a preset area in the test paper image; and according to the content of the preset area in the test paper image, determining a paper marking result of the test paper. In the invention, according to a test paper format template, a content area of the test paper is determined; through shooting or scanning, an image of the test paper to be marked is acquired, a content of a corresponding area in the image of the test paper to be marked is detected, and the detected content is identified and calculated so as to acquire the paper marking result of the test paper; the method can be applied to various kinds of test paper; automatic paper marking and result calculation are realized; a work load of manual paper marking is effectively reduced and efficiency and accuracy of test paper marking are observably increased.

Description

technical field [0001] The invention relates to the technical field of image recognition and pattern recognition, in particular to an electronic marking method. Background technique [0002] With the advent of the information age, electronic information technology continues to develop and gradually penetrates into different industries, and gradually replaces complicated manual operations, which greatly improves the efficiency of transaction processing. At present, electronic marking technology through automatic scanning has been widely used. Compared with traditional manual marking methods, electronic marking can greatly improve the speed of marking, and can effectively avoid marking errors caused by human errors and improve the accuracy of test paper evaluation. and fairness. [0003] Existing electronic marking mostly adopts the form of separating the test paper and the answer sheet. The examinee fills in the answers to the test questions on a separate answer sheet, and r...

Problems solved by technology

Although the above marking method can improve the efficiency of marking, but because the test questions and answer sheets are separated, candidates need to fill in the answers to the test questions separately on the answer sheets according to the regulations after answering the questions, which undoubtedly increases the operational complexity of the test takers.

At the same time, the existing electronic marking method needs to make a special answer sheet, and read the answer sheet information through a special card reader with a specific optical character recognition system. The printing accuracy of the answer sheet is high, and the production cost is high. Larger exams cannot be widely used in some small and medium-scale exams
