Vehicle foothold generation method and device, equipment and computer storage medium

Abstract

The invention provides a vehicle foothold generation method, and the method comprises the steps: obtaining vehicle passing track data, composed of a plurality of bayonet snapshot data, of a target vehicle, the bayonet snapshot data comprising bayonet region information and bayonet vehicle passing time information, and the bayonet region comprising at least one bayonet; judging whether bayonet area information and / or bayonet vehicle passing time information of two continuous bayonet snapshot data in the vehicle passing track data meet / meets a preset requirement or not; and if so, setting the foothold data based on the two continuous bayonet snapshot data meeting the preset requirements. According to the vehicle foothold generation method, the accuracy of foothold generation is improved.

Description

technical field [0001] The present application relates to the field of data intelligence technology, and in particular to a method, device, equipment and computer storage medium for generating vehicle footholds. Background technique [0002] With the development of society, the number of vehicles and capture devices on urban roads is increasing. Therefore, analyzing the footholds of vehicles through space-time trajectory technology has become a major means for the police to grasp the living habits of residents, and to control a group of designated vehicles to maintain urban safety. [0003] In the prior art, the foothold is determined by comparing the vehicle trajectory between the time difference between the passing time of the front and rear two checkpoints and the preset time threshold, without considering that the distance between the passing vehicle and the front and rear two checkpoints is too long to cause the time difference to exceed The factor of the preset time t...

Problems solved by technology

[0003] In the prior art, the foothold is determined by comparing the vehicle trajectory between the time difference between the passing time of the front and rear two checkpoints and the preset time threshold, without considering that the distance between the passing vehicle and the front and rear two checkpoints is too long to cause the time difference to exceed The factor of the preset time threshold, and it is determined as the foothold if the time difference of one passing vehicle exceeds the threshold, resulting in a large occasional, and the vehicle may have multiple footholds within a period of time, which reduces the accuracy of foothold generation
