[0004] However, because the planned route of the bus is not necessarily a straight line, for example, the path segment between two stations of some buses is a curved road section, or the path section between two stations is a broken line section, then according to the bus The division of path segments at certain sites will result in some road segments not being within the ellipse area, which will lead to false positives of path deviation

Abstract

The invention provides a vehicle track monitoring method and device, and the method comprises the steps: obtaining a planned path of a vehicle, segmenting the planned path into a plurality of path segments according to feature points on the planned path, and obtaining a positioning point of the vehicle at the current moment, wherein the feature points comprise one or combination of an intersection, a road inflection point and a preset road length; and determining whether the vehicle deviates from the planned path according to the deviation value of the vehicle positioning relative to the path section. By applying the embodiment of the invention, the probability of false alarm is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle monitoring, in particular to a vehicle trajectory monitoring method and device. Background technique [0002] In the technical field of vehicle monitoring, how to monitor the vehicle trajectory is an urgent technical problem to be solved. [0003] In the prior art, the invention patent with the application number CN201810638561.2 discloses a vehicle deviation detection method and device. The method includes obtaining the current driving route and current location information of the vehicle, and dividing the route into multiple road sections according to the station information. For each road section in the plurality of road sections, determine whether the current position of the vehicle satisfies the first condition and the second condition, if not, determine that the vehicle deviates from the road section, the first condition is that the distance between the current position of the vehicle and th...
