Problems solved by technology

[0004] Electronic traffic management, which has been born in recent years, has been widely used, such as: red light capture, speeding capture, etc.; but most of its systems stay on the capture of illegal vehicles, etc., and follow-up requires more labor costs and It takes time to identify the license plate, which also creates problems of heavy workload, low efficiency, and low degree of intelligence

Abstract

The invention provides a license-plate-identification-based intelligent traffic analyzing method which relates to the video analyzing technology field and comprises the following steps: 1) acquiring an original image through the use of a high-speed camera to photograph the information appearing in a current image; 2) pre-processing the image in which the acquired image is subject to gray scale processing followed by the de-noising processing; 3) positioning a license plate in which a wavelet based analyzing and positioning method is utilized to position the license plate; 4) segmenting the characters in which the image of the already positioned license plate area is subject to further processing, the character areas are accurately positioned and according to the character size characteristics, a dynamic template is used to segment the characters and the character sizes are normalized; and 5) identifying the characters in which the segmented characters are zoomed and subject to characteristic extraction so as to obtain a specific expression for the characters. And through the classification type and the classification rule to identify the inputted character images, the electronic traffic intelligent management is brought to a new level. The method can also realize the integrated acquisition and identification of electronic traffic management.

Description

technical field [0001] The invention relates to the technical field of video analysis, in particular to an intelligent traffic analysis method based on license plate recognition. Background technique [0002] In today's era of "requiring police strength from technology and efficiency from technology", with the continuous growth of the number of urban motor vehicles, while bringing many conveniences, there are also some problems. The frequent occurrence of urban road traffic accidents has caused serious damage to urban traffic management. a certain degree of difficulty. [0003] The use of scientific and technological means to achieve effective management of road traffic can not only effectively prevent such traffic violations, reduce accidents caused by them, but also deter violating drivers, promote a virtuous cycle of traffic order, and at the same time Liberate part of the traffic police, alleviate the shortage of police force to a certain extent, and truly reflect the i...
