Abstract

The invention provides a vehicle tracking method and device, which includes: when the target detection information of the car sensor feedback is received, select the target vehicle and generate the target vehicle under the self -car coordinate system; calculate the target tracking modelThe effective correlation point of the target; calculate the association score between each reference vehicle in the target vehicle and the current target tracking list to update the tracking model or establish a new reference vehicle.Based on the method of the present invention, the target model of different vehicle sensors is associated and tracking the target model of different vehicle sensors according to the effective correlation point, so as to exclude the error content in the detection information of the car sensor feedback, which improves the efficiency and accuracy of subsequent association.

Description

technical field [0001] The present invention relates to the technical field of automobile automatic driving, and more specifically, relates to a vehicle tracking method and device. Background technique [0002] With the development of ADAS (Advanced Driver Assistant System, Advanced Driver Assistance System) technology, advanced assisted driving functions such as adaptive cruise, lane keeping and automatic braking have been realized. In order to realize the automatic driving of the car, tracking the obstacles around the car body, mainly the vehicle, is very important for subsequent decision-making. [0003] At present, in order to track the target vehicle around the vehicle body, when the detection information fed back by multiple on-board sensors is fused, the center position point of the target vehicle is mainly associated. However, limited by the measurement principle of the on-board sensor itself, there are also differences in the feedback detection information. For exa...
