Abstract

The invention discloses an object tracking method and device, and relates to the field of image processing. According to the specific implementation scheme, multiple frames of first images shot by a first camera device and a first shooting moment of each frame of first image are acquired, wherein the first images comprise a first object; multiple frames of second images shot by a second camera device and a second shooting moment of each frame of second image are obtained, wherein the second image comprises a second object; a relative relationship between the first camera device and the secondcamera device is obtained; and whether the first object and the second object are the same object or not is judged 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 relative relationship. According to the object tracking method and device provided by the embodiment of the invention, the problem 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 canbe 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] In urban life, it is often necessary to track the vehicles in the driving state, and the main tracking method is realized through the shooting data of the cameras installed in the urban road network. [0003] Since the vehicle is in a driving state, a single camera cannot obtain the vehicle's driving trajectory, and it is necessary to track vehicles under different cameras. When the existing schemes track vehicles under different cameras, the scheme adopted is to judge whether the vehicles captured by different cameras are the same vehicle through a frame of image data under different cameras. When the vehicles on the two frames of images are similar When the degree reaches a certain level, the vehicles on the two frames of images are considered to be the same vehicle, so that the tracking...
