Vehicle tracking system

Abstract

The embodiment of the invention provides a vehicle tracking system. The system comprises a plurality of cameras, the cameras are used for shooting monitoring images on a monitoring road section at intervals, each camera shoots different monitoring sub-road sections of the monitoring road section, and the monitoring sub-road sections monitored by the cameras with adjacent serial numbers have overlapping areas; sending the shot monitoring image to the terminal server; the terminal server is used for receiving the monitoring images sent by the plurality of cameras and acquiring vehicle information of vehicles existing in the monitoring images; determining a target vehicle in all vehicles in which the images of the plurality of cameras exist based on the similarity of the vehicle information;and obtaining global coordinates of the target vehicle in a global coordinate system when the plurality of cameras shoot the target vehicle, wherein the global coordinates are used for displaying a track of the target vehicle in the global coordinate system. And long-distance continuous vehicle trajectory tracking can be realized.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a vehicle tracking system. Background technique [0002] In order to improve the safety of road traffic, a camera can be used to take a picture of the road on which the vehicle is driving, and the server can identify the vehicle from the picture, so as to monitor the identified vehicle. Compared with traditional manual supervision, it can effectively reduce the labor cost of road traffic monitoring. [0003] However, the monitoring range of a single camera is limited, and when a vehicle leaves the monitoring range of a camera, it cannot continue to track the vehicle. In the prior art, after one camera loses the target vehicle, another camera can be activated to continue tracking the vehicle, but it takes a certain amount of time to switch cameras, which may cause discontinuity in the tracked driving trajectory. Contents of the invention [0004] The purpo...

[0003] However, the monitoring range of a single camera is limited. When the vehicle drives out of the monitoring range of a camera, it cannot continue to track the vehicle.

In the prior art, after one camera loses the target vehicle, another camera can be activated to continue tracking the vehicle, but it takes a certain amount of time to switch cameras, which may cause discontinuity in the tracked driving trajectory
