Abstract

The invention discloses an express bar code automatic recognizing system and method based on image processing. The system comprises an express transmission main device and a sorting device; and the express transmission main device comprises a goods loading transmission belt conveyor, a sorting transmission belt conveyor, a manipulator and an industrial personal computer. The method comprises the steps that 1, goods loading transmission of expresses is recognized; 2, an image sequence of three surfaces of the expresses is obtained; 3, bar code areas in the image sequence of the three surfaces of the expresses are partitioned; 4, whether a complete bar code area is extracted successfully or not is judged; 5, express sorting information is extracted, and the expresses are sorted; 6, the manipulator overturns the expresses; 7, sorting transmission of the expresses is recognized; 8, an image sequence of another three surfaces of the expresses is obtained; 9, bar code areas in the image sequence of another three surfaces of the expresses are partitioned; 10, whether a final bar code area is extracted successfully or not is judged; and 11, exception handling of the expresses is conducted. The express bar code automatic recognizing system and method based on image processing do no need to limit a bar code paste face, the automatic express bar code recognition efficiency is high, and labor operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of logistics sorting, in particular to an image processing-based express barcode automatic recognition system and method. Background technique [0002] Express barcode automatic identification technology is currently one of the hotspots that domestic and foreign express delivery companies pay attention to and focus on research. It is widely used in all aspects of express mail processing, and the express sorting link has a great impact on the processing speed and delivery time of express mail. At present, the express sorting work is mostly done by automatic sorting machines. The collection of sorting machine control signals requires manual operation. There are two main methods. One is to manually scan the bar code on the express with a hand-held bar code scanner, and the other One is to manually flip the express to fix the barcode sticking surface in a certain direction, and the laser scanner scans the code i...
