Abstract

The invention discloses a multi-point sensing fusion method and device, and a computer-readable storage medium. The method includes: dividing the sensing area into a spatial grid, and marking the grid where the overlapping area of ​​the sensing area corresponding to multiple points is located, Determine the number of points corresponding to each overlapping area; obtain the target detection information of multiple points, and determine the grid where the tracking target is located at each point based on the target detection information; based on the grid where the overlapping area is located and the tracking target location Grid, determine the tracking target that appears in the overlapping area; traverse each overlapping area, and determine whether the number of points corresponding to the overlapping area is greater than or equal to 3; if so, calculate any two tracking points from different points in the overlapping area The coincidence degree of the target generates a coincidence degree matrix; the target clustering is performed based on the coincidence degree matrix, and the numbers of the tracking targets clustered into the same group are merged. The present invention combines repeated targets under multi-point perception to improve target tracking efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination and target tracking, in particular to a multi-point perception fusion method and device, and a computer-readable storage medium. Background technique [0002] In order to achieve safe driving on the actual road, the self-driving vehicle not only needs on-board sensors to detect the road conditions and surrounding environment of the vehicle, but also needs roadside sensors to transmit information far larger than the sensing range of on-board sensors to the vehicle to assist the vehicle in autonomous driving. [0003] In the roadside sensing system, there may be multiple sensors monitoring the same area, and there may be overlapping areas when the sensing information is transmitted from multiple points in the area. If it is not handled properly, it may cause mutual interference and reduce the accuracy of sensing. Contents of the invention [0004] The problem solved by the presen...
