Locating Method for Character 2D Barcode

Abstract:

This paper studies the locating method for character 2D barcode. In this kind of character 2d barcode, the solid circle is designed as the position detection patterns. The locating method for character 2D barcode is different with the traditional method for DM barcode. In this paper, according to the geometric characteristics of the solid circle, connected region regarded as suspected solid circle can be filtered through the cross method rapidly. Then the edge of connected area is detected through the shape angle and the solid circle can be found through the circularity values. Experiment results show that this method can locate the character 2D barcode rapidly and effectively.
