Abstract

The embodiment of the present application discloses a method, device, device, and medium for estimating a permanent point. The estimating method disclosed in the embodiment of the present application includes acquiring the coordinate data of the moving body within a set time period, and targeting The coordinates of the included coordinate points are clustered and analyzed, and the coordinates of each coordinate point are divided into multiple coordinate groups; according to the coordinate time of each coordinate point, the group size of each coordinate group is respectively attenuated to obtain the corresponding group Effective scale: According to the coordinate distribution density of each coordinate point of the optimal group with the largest effective group size, estimate the permanent point of the active body. The embodiment of the present application improves the accuracy of the resident point estimation and reduces the time lag of the resident point estimation.

Description

technical field [0001] The present application relates to the technical field of geographic information, and in particular to a method, device, equipment and medium for estimating permanent points. Background technique [0002] With the wide application of positioning technology in smart terminals, the user's coordinate data can be collected for a period of time through the user's terminal, and then the user's resident point (such as residence and company address, etc.) can be determined according to the user's coordinate data. , similarly, the resident points of other active bodies can also be obtained. The resident point can provide support for various location-based services (Location Based Service, LBS) related services. [0003] In the prior art, for the coordinate data of the moving body, the resident point of the moving body is usually determined by artificially setting rules or cluster analysis. [0004] However, with the above method, the accuracy of the obtained ...
