Radar visual collaboration method and device for traffic intersection, equipment and medium

Abstract

The embodiment of the invention discloses a radar visual collaboration method and device for a traffic intersection, equipment and a medium. The method comprises the following steps: determining a current visual image shot by an image collector towards a preset traffic intersection through current rotation; adopting a radar cooperating with the image collector to determine an estimated position of a target concerned object appearing in the current visual image after the image collector rotates by one circle from the direction towards the preset traffic intersection; and controlling the image collector to track and shoot the target concerned object according to the estimated position when rotating to the preset traffic intersection again to shoot the next visual image. According to the technical scheme provided by the invention, the image collector and the radar work cooperatively, the tracking of the target concerned object is realized through the periodic monitoring of the traffic intersection and the position estimation of the target concerned object, and the monitoring cost is reduced while the omnibearing monitoring of the traffic intersection is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a radar vision collaboration method, device, equipment and medium for traffic intersections. Background technique [0002] At traffic intersections, such as 4-fork or 5-fork, etc., it is necessary to monitor the traffic intersection and track suspicious objects appearing at the traffic intersection. [0003] In related solutions, a fixed-focus camera is configured for each intersection to achieve wide-angle shooting; at the same time, in order to track suspicious targets, it is also necessary to configure a PTZ dome camera for each intersection to achieve tracking and shooting of moving targets. 10 cameras are needed at the intersection, and the cost is relatively high. However, if a single camera is used and placed in the center of the turntable for 360-degree rotation to shoot, it will not be possible to track the target well. ...
