Abstract

The invention is applicable to the technical field of vehicle radar, and provides a target track association method, radar and terminal equipment. The method includes: acquiring measurement information and track of a tracking target, establishing a cost matrix according to the measurement information and track; deleting tracks in the cost matrix that are not associated with any of the measurement information and The measurement information associated with the track is obtained as a matrix to be associated; and the measurement information associated with the track of the tracking target is obtained according to the matrix to be associated. While ensuring the accuracy of the association, the present invention greatly reduces the association operation time and improves the track association speed.

Description

technical field [0001] The invention belongs to the technical field of vehicle radar, and in particular relates to a target track association method, radar and terminal equipment. Background technique [0002] Target detection, association, and tracking are the technical basis for automotive radar to achieve functions such as collision warning, active obstacle avoidance, and adaptive cruise. The radar will obtain the measurement information of multiple targets in one detection, and which measurement information comes from which target track is uncertain, so it is necessary to associate the measurement information with the track. However, the existing track correlation methods are computationally complex, especially when the number of targets in the scene is large, the amount of correlation calculation increases significantly, which seriously affects the efficiency of target tracking. Contents of the invention [0003] In view of this, an embodiment of the present inventio...
