Abstract

The embodiment of the invention discloses a multi-camera target matching and tracking method and device for an automobile. In the method, a target in each path of video frame image is tracked in a mode of matching a detected target of the current video frame image with a detected target of a video frame image in the path for each path of current video frame image, and the target in each path of video frame image is tracked in a mode of calculating a three-dimensional position coordinate difference and appearance similarity. Two targets with high appearance similarity and similar three-dimensional positions are determined as the same target, the target of matching the targets in the multi-channel video frame is achieved, and due to the fact that not only the three-dimensional positions but also the appearance similarity are considered during multi-channel target matching, the accuracy of multi-channel target matching is greatly improved, and therefore the accuracy of multi-channel target matching is improved. According to the multi-camera target matching and tracking device for the automobile, provided by the embodiment of the invention, the multi-camera target can be tracked, and the target matching accuracy is relatively high.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a multi-camera target matching and tracking method and device for automobiles. Background technique [0002] At present, in order to realize the 360-degree visual perception of the unmanned vehicle, multiple cameras are installed on the unmanned vehicle, and the shooting areas of two adjacent cameras overlap. [0003] In order to realize automatic driving in a multi-camera scenario, it is necessary to perform target tracking on the videos collected by multiple cameras installed on the unmanned vehicle. Since multiple cameras may capture the same target, it is also necessary to match the same target captured by multiple cameras, because if the matching accuracy is low, it will seriously affect unmanned driving. [0004] Therefore, there is an urgent need for a method that has high target matching accuracy and can track multi-camera targets. Contents of the invention ...
