Vehicle identification method based on single frame image and apparatus thereof

Abstract

The invention discloses a vehicle identification method based on a single frame image. The method is used in the intelligent traffic field and is used to solve problems that identification kinds are less and an identification rate is low in the current vehicle identification. The method comprises the following steps: according to the collected single frame image, carrying out initial road calibration and acquiring scale information of vehicles at different positions; when current time is daytime, detecting a vehicle bottom area and a vehicle window area respectively and acquiring the vehicle position information; if the current time is night, detecting a car light area and a vehicle window position and acquiring the vehicle position information; according to the scale information and the position information, using a symmetry to acquire a profile diagram of the object vehicle; according to the profile diagram, carrying out vehicle type identification. According to the embodiments of the invention, various types of the vehicles can be rapidly and high-efficiently identified and a demand of road traffic law enforcement can be satisfied.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, in particular to a vehicle recognition method and device based on a single frame image. Background technique [0002] In the field of intelligent transportation, vehicle recognition is a very important technology. Vehicle identification technologies currently on the market can be mainly divided into contact and non-contact. Contact vehicle recognition is to bury the sensor in the ground during the implementation process, and the sensor will perform induction recognition when the vehicle passes by. The disadvantage is that the construction is complicated, and the installation process has a great impact on the reliability and life of the sensor, and the sensor is easily damaged by heavy vehicles. The maintenance cost is high, and the traffic needs to be interrupted when the sensor is installed and repaired, which will damage the road surface and affect the life of the road surface...
