Problems solved by technology

[0004] However, there is currently no method to mine frequent regions and quantify how often moving objects enter and exit frequent regions
Therefore, it is currently impossible to analyze the trajectory frequency as a factor of behavior analysis and safety risk, which brings great difficulties to the behavior analysis of moving objects and safety risk evaluation.

Embodiment Construction

[0026] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0027] figure 1 is a flowchart of a method for calculating track frequency according to an exemplary embodiment of the present disclosure. Such as figure 1 As shown, the method may include the following steps:

[0028] In step 110, a track point set of the moving object is obtained.

[0029] In the present disclosure, the mobile object may refer to a vehicle, a user holding a mobile device, and the like. The trajectory can be, for example, the driving trajectory of the vehicle, and the data can be obtained by a GPS device, including longitude, latitude, time and other information of a series of location points passed by the vehicle. The continuous locati...

Abstract

The present disclosure relates to a method and apparatus for calculating trajectory frequency, a storage medium, and an electronic device. The method may include obtaining a set of trajectory points of a moving object; a density-based clustering partition is carried out on the track points in the track point set by using a preset neighborhood radius and a preset neighborhood track point density threshold, and a plurality of cluster sets are obtained; measurement of data center trends is performed on the plurality of cluster sets to obtain the track frequency of the moving object. The method can accurately calculate the trajectory frequency of the moving object in the frequent region, and provides a new quantitative index for the behavior analysis of the moving object and the security riskevaluation.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method, device, storage medium and electronic equipment for calculating track frequency. Background technique [0002] With the rapid development of Internet of Things technology, a large amount of travel data of mobile objects has been accumulated. For example, in the field of Internet of Vehicles, a large amount of driving data of users has been accumulated. At present, the user's behavior analysis and safety risk assessment are generally carried out through the travel time, mileage, speed, and road status in the driving data. [0003] For mobile objects such as private car owners or fleets, with the accumulation of data, the distribution of trajectories will be concentrated in certain areas. These areas represent the range of activities that mobile objects often enter and exit, which can be called frequent areas. These frequent areas are closely related to the ...
