Problems solved by technology

The stop points calculated in this way are inaccurate and may deviate greatly from the real stop points
It is possible to mistake the track points obtained in the case of congestion operation as stops, or some of the stops may be ignored. If these track points are used to obtain stop point information, then the accuracy of the obtained stop point information will be poor.

Abstract

The invention discloses a method and a device for determining vehicle parking location information. The method comprises the steps of performing track point data traversal of a vehicle, and determining an operation set, a candidate parking set and an unknown set which correspond with the track point data; if the unknown set and the candidate parking set satisfy a preset vicinity condition, an added distance of all track points in the unknown set is smaller than a first added distance threshold, and the average distance is smaller than a first average distance threshold, merging the track points in the unknown set into the candidate parking set in vicinity of the known set; performing filtering processing on the track points in the candidate parking set; and screening the candidate parking set according to at least one selected from parking time length, average radius and straight-to-curve ratio of the candidate parking set for obtaining the parking set. The method and the device according to the invention can improve accuracy in determining the vehicle parking location information.

Description

technical field [0001] The embodiment of the present invention relates to an intelligent terminal technology, and in particular to a method and device for determining vehicle stop information. Background technique [0002] In the Internet of Vehicles technology, point of information (POI) analysis is an important field. Accurate analysis of vehicle stop information is helpful to understand the driving behavior of vehicles. In the analysis process of the stop information, the determination of the stop is the basis of the analysis of the stop information. The accuracy of the stop point directly affects the accuracy of the output result of the stop point information. According to information points such as logistics parks, gas stations, and service areas where vehicles often stop, it can effectively analyze and obtain information such as the type of goods transported by vehicles, and the gas stations commonly used by vehicles. Therefore, the acquisition of truck stop informat...
