A road traffic vehicle feature extraction system

Abstract

The invention discloses a feature extraction system of a road traffic vehicle. The feature extraction system comprises a vehicle image acquisition module, a vehicle image model construction module, anedge contour detection module, an enhancement processing module and a feature extraction module, Wherein the vehicle image acquisition module is respectively connected with the vehicle image model module and the edge contour detection module, the edge contour detection module is connected with the enhancement processing module, and the enhancement processing module is connected with the feature extraction module. According to the feature extraction system of a road traffic vehicle, the Edge profile detection module and the enhancement processing module carry out edge and information enhancement processing on the acquired vehicle image, and processes the vehicle angular point distribution information in a simulation invariant region through the feature extraction module so as to realize extraction of vehicle pixel feature points, so that the vehicle pixel feature points have the characteristic of high feature extraction accuracy, and a foundation is laid for intelligent identificationof vehicle features in the later period.

Description

technical field [0001] The invention belongs to the technical field of vehicle image processing, and relates to a feature extraction system for road traffic vehicles. Background technique [0002] With the continuous growth of car ownership and increasing traffic pressure on the road, the safety management issues related to cars have become increasingly prominent. In order to achieve optimal management and scheduling of running cars, effective detection and identification of car features can be used as driving Provide visual information reference for personnel and vehicle management and dispatching centers. Through the intelligent identification of vehicle features, the existing vehicle feature extraction in road traffic has the problem of poor accuracy, and it is impossible to accurately identify vehicles based on vehicle features. In addition, Vehicle feature extraction has important application value in the fields of vehicle safety management and road traffic control, and...
