Title:
MOTION TRAJECTORY PROCESSING METHOD, MEDIUM, APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/115143
Kind Code:
A1
Abstract:
The present application relates to a motion trajectory processing method, comprising: obtaining a motion trajectory set, the motion trajectory set comprising a plurality of motion trajectories; determining motion path elements according to the motion trajectory set, the motion path elements comprising at least one of a center position and an intersection point set, the center position being shared by a plurality of grids and the motion trajectory set being contained in a geographic range of a plurality of grids; the intersection set comprises a plurality of intersections related to a plurality of trajectory segment clusters, each of the plurality of trajectory segment clusters comprising a plurality of trajectory segments of a plurality of motion trajectories, and furthermore, the distance between adjacent trajectory segments among the plurality of trajectory segments being less than a predetermined value, the adjacent trajectory segments respectively belonging to different motion trajectories among the plurality of motion trajectories. In the present application, determining the center position and/or intersection set of a plurality of motion trajectories can reduce the cost of storage and processing of motion trajectories, improving motion-trajectory processing efficiency.
