Benefits of technology

This technology allows vehicles to generate their own route without human interference or guidance. Each car has its best location based upon previous locations along it's path. These routes help guide them towards destination destinations with greater efficiency compared to traditional methods like road maps. They also allow drivers to see what they have been driving through before but only when needed. Overall this system makes navigation faster and easier over large distances while maintaining accurate data about traffic flow patterns.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving the performance of navigation systems used on vehicles during transit operations without sacrificing computational resources or requiring manual intervention.

Abstract

The invention discloses a line trajectory generation method and device, relates to the technical field of computers, and can solve the problems of low drawing efficiency and low accuracy of manual drawing of line trajectories in the prior art. The method mainly comprises: determining track characteristics of each positioning track for the same always-on point, wherein the positioning tracks are sets of positioning points arranged according to the time sequence, and the track characteristics are characteristics used for measuring the quality of the positioning tracks; selecting an optimal positioning track from a plurality of positioning tracks according to the track characteristics; performing point distance optimization processing on the optimal positioning track to obtain an initial clustering center point set; and clustering iteration is performed on the multiple positioning tracks and the initial clustering center point set so as to obtain a final clustering center point set, and enabling adjacent points in the final clustering center point set to be connected so as to obtain a line track. The method and the device are mainly suitable for scenes where bus route tracks are drawn.
