Embodiment Construction

[0025] The present invention takes the objective question answer sheet as an example to illustrate the information identification method for filling and painting information cards. IMR (ImageMark Recognize, image symbol recognition).

[0026] Use the making requirement of the answer sheet of the information identification method of filling information card of the present invention as follows: IMR relatively OMR to the requirement that answer sheet prints have significant decline, (OMR answer sheet such as figure 1 shown), IMR requires that the answer sheet should be printed with horizontal / vertical synchronization heads (such as figure 2 shown), the synchronization heads in these two orientations are used to determine the grid coordinates of the entire answer sheet; the area that students can fill in is called the identification area, and the center of this area corresponds to the center position of the horizontal / vertical synchronization head .

[0027] The production requ...

Description

technical field [0001] The invention relates to an information identification method for filling and painting an information card, in particular to an information identification method for an objective question and answer sheet. Background technique [0002] Optical Mark Reader (OMR for short) is a fast entry device for computers. It integrates mechanical, optical and electrical technologies, and is widely used in standardized examinations and various statistics due to its fast and reliable performance. OMR first appeared in the 1960s, and now the system is widely used in information processing systems such as examination papers, scoring, statistics and even horse racing at home and abroad. [0003] The optical label reader is a device that uses the principle of photoelectric conversion to convert the optical information symbols on the information card in the specified format into electrical signals that can be processed by the computer. The information card is usually a p...
