Abstract

The invention discloses a method and a system for identifying automobile license plates automatically based on image analysis. The method comprises the following steps of: determining a license plate region image comprising license plate information from an acquired license plate image comprising the license plate information; retaining Chinese characters, letters and number information in the determined license plate region, and removing other parts simultaneously; extracting a single character from the retained license plate information; and identifying the extracted single character in real time. By the method and the system for identifying the automobile license plates automatically based on the image analysis, the shortcomings of high auxiliary working capacity, low controllability, unfavorability for management and the like can be overcome, so that the advantages of low auxiliary working capacity, high controllability and favorability for management can be realized.

Description

technical field [0001] The invention relates to the field of intelligent traffic management systems, in particular to a method and system for automatic identification of vehicle license plates based on image analysis. Background technique [0002] At present, automatic license plate recognition technology is a fusion of computer vision, image processing technology and pattern recognition technology, and is a very important technology in intelligent transportation systems. The car image containing the license plate is captured by the camera, and after a series of image processing and pattern recognition processes, the license plate number string is output. This technology has broad application prospects in toll management stations of expressways and bridges, large parking lots, violation monitoring of traffic departments, and hunting down vehicles involved in accidents. [0003] In recent years, recognition techniques based on image understanding have attracted much attentio...
