Title:
TRAJECTORY DETERMINATION METHOD AND APPARATUS, AND TIME RECOMMENDATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/057275
Kind Code:
A1
Abstract:
Provided are a trajectory determination method and apparatus, and a time recommendation method, apparatus and system, which relate to the technical field of logistics. The trajectory determination method comprises: acquiring trajectory information of multiple trajectory points of a first object within a set time period, wherein the trajectory information of each trajectory point comprises the geographic location of the trajectory point and the time when the first object is located at the trajectory point; clustering the multiple trajectory points according to the geographic locations of all the trajectory points to obtain multiple regions which do not overlap each other, wherein the density of trajectory points in each region is greater than a preset density; determining the time corresponding to each region according to the time of at least one trajectory point in each region; arranging the multiple regions according to the times corresponding to each region to obtain a regional motion trajectory of the first object; and determining a frequent trajectory of a frequent motion of the first object based on multiple regional motion trajectories, wherein the frequent trajectory comprises a frequent region and a frequent time period corresponding to the frequent region.
