Abstract

The embodiment of the invention provides an object tracking method and a device, and the method comprises the steps: obtaining a plurality of frames of first images photographed by a first photographing device and the first photographing moment of each frame of first image, and the first image comprises a first object; obtaining a plurality of frames of second images shot by a second camera deviceand a second shooting moment of each frame of second image, wherein the second image comprises a second object; obtaining the distance between the first camera device and the second camera device; and judging whether the first object and the second object are the same object according to the multiple frames of first images, the first shooting moment of each frame of first image, the multiple frames of second images, the second shooting moment of each frame of second image and the distance. According to the object tracking method and the device provided by the embodiment of the invention, theproblem that the robustness of the existing scheme is poor due to the fact that the existing scheme is greatly influenced by the image shooting angle can be solved, and the tracking result is more accurate.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an object tracking method and device. Background technique [0002] With the increase of city scale, the effective management of vehicles becomes more urgent. In real life, it is often necessary to track vehicles in the driving state, and the main way to track vehicles is through multiple cameras in the urban road network. In the urban road network, cameras are set up in different areas. When a vehicle passes through the monitoring area of ​​the camera, the general location of the vehicle can be known. [0003] The existing method for tracking a vehicle is mainly to analyze the traveling track of the target vehicle according to the target vehicle captured in the surveillance video of the camera by obtaining a surveillance video of a camera, and to track the target. Since the vehicle is generally in a driving state, it is difficult for a single camera to e...
