TWO-DIMENSION CODE, DECODING METHOD THEREOF AND PRINTING PUBLICATION FOR APPLYING TWO-DIMENSION CODE

摘要

A two-dimensional code, a decoding method thereof and the printing publication for applying the two-dimensional code. The area of the positioning points located at the four corners of the code in the two-dimensional code characters is larger than that of the data points. The two-dimensional code is printed on the printing publication to be identified by the device. The decoding method comprises the following steps of: reading the two-dimensional code by using a reading device; detecting the margin of each point to obtain the margin image; parsing the margin image to obtain the closed border; computing the area within the closed border in order to select the positioning points; matching the positioning points in the rectangle mode; grouping the data points after selecting one separate code character; reconstructing the array of data points; and recovering the code words.
