Method and system for generating vehicle driving route

Abstract

The invention discloses a method and system for generating a vehicle driving route, wherein the method includes: acquiring a plurality of track points collected during the driving process of the vehicle, and track point information of each track point; and sequentially calculating adjacent tracks according to the track point information The distance and time interval between points, the adjacent trajectory points whose distance exceeds the preset distance or the time interval exceeds the preset time are segmented to segment the trajectory, and the trajectory point set is obtained; each trajectory point is taken as the center point in turn, Obtain all the road segments in the preset area around the track point, and match each road segment with the track point according to the preset matching rules to confirm the optimal road segment corresponding to the track point; gather all track points in the same track point to correspond to The optimal road section generates the route corresponding to the trajectory point set, and then merges the routes corresponding to all the trajectory point sets to obtain the final route. Through the above method, the present invention can use the track points to generate a track route with a high degree of matching with the actual route.

Description

technical field [0001] The invention relates to the technical field of vehicle driving route generation, in particular to a method and system for generating a vehicle driving route. Background technique [0002] In the logistics industry, all kinds of vehicles are indispensable for the transportation of goods. By installing positioning equipment on the vehicle, real-time uploading of vehicle positioning track information can be realized. Through these positioning track information, combined with electronic maps, real-time Monitor vehicle location and view the vehicle's trajectory. [0003] However, in reality, the accuracy of the location information acquired by the positioning device is affected by many factors. For example, in the case of bad weather or dense tall buildings, there will be a large positioning deviation, and it may be located in water or in buildings. As a result, the deviation between the generated vehicle trajectory and the actual vehicle route is too lar...
