Problems solved by technology

This method has relatively large limitations, and has the disadvantages of repeated capture and missed capture. Especially at intersections, the possibility of repeated capture will be greater
[0005] It can be seen that the accuracy of current vehicle tracking methods is not high, which directly affects the efficiency of intelligent transportation systems.

Embodiment Construction

[0020] In the embodiment of the present invention, after the current frame image is obtained by the camera, the license plate of each vehicle in the detection area of ​​the current frame image is identified, and the license plate information of each license plate identified is combined with the license plate information of each target point to be tracked. Information is matched, and according to the matching result, it is determined whether each license plate identified is a target point to be tracked. Wherein, when the license plate information of a recognized license plate matches the license plate information of a target point to be tracked, the identified license plate is the target point to be tracked; When the license plate information does not match, it is determined that the recognized license plate is not a new target point to be tracked.

[0021] For the target point to be tracked that does not appear in the detection area, it is determined whether the target point t...

Abstract

A method and a device for tracking a vehicle are used for improving the efficiency of an intelligent transportation system. The method comprises: determining a license plate recognized in a detection region of a current video image frame as a current target point (101); if license plate information of the current target point matches license plate information of a target point to be tracked, determining the current target point as the target point to be tracked and updating tracking list information of the target point to be tracked (103); otherwise, determining the current target point as a new target point to be tracked, and establishing tracking list information of the new target point to be tracked (104).

Description

technical field [0001] The invention relates to the technical field of intelligent traffic monitoring, in particular to a vehicle tracking method and device. Background technique [0002] With the rapid development of the city, the population and vehicles in the city are increasing rapidly, the traffic flow is increasing, and the traffic congestion is becoming more and more serious. The traffic problem has become a major problem in urban management, which seriously hinders the development of the city. The phenomenon of vehicle violations occurs anytime and anywhere, which makes the monitoring of urban traffic very difficult. Therefore, the intelligent transportation system using video tracking technology of moving objects to monitor vehicles has emerged. [0003] Current vehicle tracking methods include: license plate-based tracking and capture methods and motion information-based tracking and capture methods. Wherein, the tracking capture method based on the license plate ...
