Document Type and Number:
WIPO Patent Application WO/2023/241002
Kind Code:
A1
Abstract:
A radar-vision collaborative target tracking method and target tracking system. The radar-vision collaborative target tracking method comprises: obtaining a first image of a first vehicle at an entrance node to determine vehicle information, and sending, to an adjacent intermediate node, the vehicle information and a time point at which the first vehicle passes a recognition node corresponding to the entrance node; determining traveling information of the first vehicle at the intermediate node on the basis of radar tracking information, and sending, to a next node, the time point at which the first vehicle arrives at the recognition point and the vehicle information; determining the traveling information at an exit node on the basis of the radar tracking information, obtaining a second image of the first vehicle to determine vehicle information, and when the vehicle information determined according to the second image is consistent with the received vehicle information, determining that the tracking is correct. A vehicle is tracked by using a radar at the intermediate node, and when the present application is applied to a tunnel scene, the provision of cameras in a tunnel can be avoided, and high-precision tracking of vehicles in the tunnel is achieved.
