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] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

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

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

[0029] In the present disclosure, the moving object may refer to a vehicle, a user holding a mobile device, or the like. The track may be, for example, the driving track of the vehicle, and the data may be acquired by a GPS device, including information such as longitude, latitude, and time of a series of location points passed by the vehicle. The continuous positi...

Abstract

The present disclosure relates to a method, device, storage medium and electronic equipment for calculating track frequency. The method may include: acquiring a track point set of a moving object; using a preset neighborhood radius and a preset neighborhood track point density threshold to perform density-based clustering and division of the track points in the track point set to obtain several cluster set; measure the trend of the data center for the several cluster sets to obtain the track frequency of the moving object. This method can accurately calculate the track frequency of the moving object in the frequent area, which is useful for mobile object behavior analysis, security Risk assessment, etc. provide new quantitative indicators.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method, an apparatus, a storage medium and an electronic device for calculating the frequency of a trajectory. Background technique [0002] With the rapid development of IoT technology, a large amount of travel data of moving 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, user behavior analysis and safety risk assessment are generally carried out through the travel time, mileage, speed, and road state in the driving data. [0003] For moving 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 moving objects often enter and leave, which can be called frequent areas. These frequent areas are closely related to the...
