Answer sheet used for automatic paper scanning and inspecting and application method thereof

Abstract

The invention provides an answer sheet used for automatic paper scanning and inspecting and an application method thereof, and belongs to the technical field of image-text printing, image recognition and automatic data acquisition. The answer sheet comprises an answer sheet information area, an objective item answer selecting area, a subjective item answering area and a subjective item score teacher-marking area. Especially, subjective item score marking frames are fixed and positioned, and the answer sheet can be a universal standard answering sheet, or, positions of answering bar codes are freely arranged. The application method of the answer sheet includes the following steps that the answer sheet is edited and manufactured, an examination is conducted, subjective items are read over by teachers, scores and good and bad answers are marked by the teachers, the answer sheet is scanned, objective items are automatically read over by a system, the scores of the subjective items are counted, and a score assessment report for all the items is generated. The system has the advantages that read-over of the objective items and scoring of the subjective items can be simultaneously completed and the scores of all the items can be assessed and reported through one-time scanning, and the answer sheet is easy to edit, high in image recognition efficiency and accuracy and convenient to use.

Description

technical field [0001] The invention belongs to the technical fields of graphic printing, image processing and recognition, and automatic data collection, and in particular provides an answer sheet for automatic scanning and marking, which includes answers and score information for all objective and subjective questions, and especially relates to a An application method that uses image processing and recognition technology to automatically mark and collect the answers and score information of the answer sheet. Background technique [0002] The usual exams contain both objective and subjective questions, through which students' academic performance and teachers' teaching quality can be comprehensively evaluated.

Problems solved by technology

But this system method also has a big flaw, resulting in poor practicality

First of all: the score mark box needs to be given positioning size parameters according to the size of the answer area required for each subjective question, which is used to locate the filling points during scanning and marking and image recognition. Due to the different forms of answer sheets, the ability of teachers is uneven. This operation increases the difficulty of editing and making answer sheets, especially when the number of questions is large, it is very cumbersome

Second: the score box and the answer area are arranged in a mixed manner, so it is inconvenient to make a general answer card product

Third, the score box and the answer area are arranged in a mixed manner, which is easy to be accidentally painted by candidates, resulting in misinterpretation of data during scanning

Fourth, these score mark boxes are arranged according to the answer area and position requirements, and are positioned irregularly. It is easy to cause the answer card to fill in the selection box or write the answer at the same position on the front and back of the answer card, and it is easy to damage the answer card. Misread

Fifth, the score mark boxes are distributed in a large range on the answer sheet, and the scanning position is slightly deviated, which is easy to cause misreading
