Abstract

The invention discloses a vehicle identification method and device, belonging to the technical field of intelligent transportation. The method includes: acquiring a first image, the first image is obtained by collecting images of the side of the vehicle; performing vehicle detection on the first image to obtain a vehicle area in the first image; The wheel is detected in the area to obtain the wheel area in the vehicle area; according to the number of the wheel area, the number of axles of the vehicle is determined. The present invention collects the image of the side of the vehicle. Since the side image generally includes the wheel area of ​​the vehicle, the vehicle detection is performed on the image. After the vehicle area is determined, the wheel detection is further performed on the vehicle area to determine the wheel area. Quantity, to determine the number of axles, so that the model can be further subdivided, providing more accurate vehicle information.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle identification method and device. Background technique [0002] The intelligent transportation system is a real-time, accurate and efficient comprehensive transportation system that effectively integrates advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground traffic management system. management system. Vehicle identification is an important part of the intelligent transportation system. Vehicle information can be obtained through vehicle identification, which is of great significance to the realization of highway traffic automation. [0003] At present, the relevant technology generally uses a camera installed at the bayonet to collect images of the vehicle. Whenever a vehicle touches the white line at the intersection, the camera ...
