Abstract

The invention discloses a vehicle identification method. The method comprises the steps of acquiring a to-be-identified vehicle image of a to-be-identified road section; extracting concave points andconvex points of the to-be-identified vehicle image, and constructing a concave point model and a convex point model of the to-be-identified vehicle image according to the concave points and the convex points; and based on the concave point model and the convex point model, pairing the to-be-identified vehicle image with a vehicle image database to obtain a vehicle identification result of the to-be-identified vehicle image, and obtaining a traffic flow condition of the to-be-identified road section. The invention further discloses a vehicle recognition device, the problem that in the prior art, the feature extraction difficulty of the road traffic vehicle is large can be effectively solved, the vehicle image features can be stably extracted, and the high recognition degree is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle identification, in particular to a vehicle identification method and device. Background technique [0002] As the number of cars continues to grow, the traffic pressure on the road continues to increase, and the safety management issues related to cars are becoming more and more prominent. In order to achieve optimal management and scheduling of running cars, effective detection and identification of car features can be used. Obtain the number of vehicles and provide visual information reference for drivers and vehicle management dispatch centers. Vehicle recognition has important application value in the fields of vehicle safety management and road traffic control, and the study of vehicle feature extraction methods also has a good application prospect in the detection of vehicle-related crimes. [0003] At present, the feature extraction system of road traffic vehicles uses the edge contour det...
