Character recognition method and system based on template character library

Abstract

The invention discloses a character recognition method and system based on a template character library. The character recognition system comprises a camera device and a computer which is connected to the camera device and which is installed with image processing software and character recognition software. The camera device is used for shooting a to-be-recognized character zone of a to-be-measured product, and sending a captured image containing the to-be-recognized character zone to the computer. The computer is used for preprocessing the captured image to obtain a binary image, separating the to-be-recognized character zone from the binary image, performing image segmentation of each to-be-recognized character image in the to-be-recognized character zone, recognizing multiple to-be-recognized character images subjected to segmentation one by one by comparing with the template character library, and showing recognized characters according to a set character recognition sequence. The invention can greatly improve the recognition accuracy and the recognition efficiency of numbers, or letters, or combined characters of numbers and letters, and can be applied to the technical field with extreme high requirements for character recognition accuracy.

Description

technical field [0001] The present invention relates to the technical field of character recognition, more specifically, to a character recognition method and character recognition system based on a template character library. Background technique [0002] OCR (Optical Character Recognition, Optical Character Recognition) has powerful and practical features, and has been widely used in the field of character recognition technology. However, the current OCR still has the technical defects of low character recognition accuracy and character recognition efficiency. The application in the technical field (for example, product anti-counterfeiting detection) that requires extremely high accuracy of character recognition is limited to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a character recognition method and character recognition system based on a template character library for the above-mentio...
