A method for identifying RMB prefix codes

Abstract

The invention discloses a method for recognizing Renminbi (Chinese currency yuan) crown codes, and belongs to the technical field of pattern recognition, and can be applicable to printed character recognition in multiple application scenarios. The method includes: first, obtaining information of the Renminbi images, like inclined angles, orientations, versions, angular points positions, and eliminating backside images; secondly, performing initial location of the crown code area while correcting and normalization Renminbi images, the synchronous completion of the location, correcting and converging processes saving time and space cost and eliminating a large amount of redundant information; then applying an algorithm which is based on traversing degree features to the crown codes which are initially located for further accurate location, and applying the e method based on the Sliding Window Algorithm to the character string so as to segment the character strings into a plurality of individual characters; finally conducting no-deformation treatment on the characters, normalizing the large or small positions of the characters, and extracting the features of the characters and inputting the features to a classifier model so as to complete the recognition. The method provides a fast and accurate way of Renminbi crown codes recognition, and thus greatly increases the accuracy and speed in recognizing the Renminbi crown codes.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition, and more specifically relates to a method for recognizing RMB prefix codes. Background technique [0002] With the development of pattern recognition and artificial intelligence science and technology, it is becoming a reality step by step to replace humans with more labor. In recent years, character recognition technology (OCR technology) has become increasingly mature, and RMB prefix code recognition is an important application occasion of character recognition technology. The RMB prefix code recognition technology has become an important indicator in the national standard of the next generation of ATM machines. [0003] my country's OCR technology started relatively late, only gradually starting in the 1970s. At present, my country's OCR technology continues to mature, especially Chinese character recognition technology, which is now in a leading position in the world. However, ...

Problems solved by technology

Moreover, the identification of the prefix code requires a recognition rate as high as 99.9%, and almost no recognition errors are allowed. At present, there are few domestic research results specifically aimed at the RMB prefix code.
