Abstract

The invention relates to the technical field of software engineering research and discloses a positioning-data trajectory tracking method. The positioning-data trajectory tracking method includes the following steps of A), acquiring neighboring positioning points of P1 and P2; B), acquiring road data matched with the P1 and a road element point set in the road data; C), sequentially acquiring points located ahead of the P2 and included in the road element point set for moving points along the moving direction of a vehicle when the road matched with the P1 is a curve; D), drawing trajectories according to coordinates of the P1, the moving points and the P2; wherein if the number of the moving points is larger than 1, arraying the drawn trajectories according to the order acquired. By the aid of analysis of the neighboring positioning points, the proper points in the road element point set are selected as the moving points of the vehicle, untruthfulness in drawing of the trajectories due to the fact that the neighboring positioning points are scattered therebetween is improved, and the accurate, true and smooth trajectories can be acquired by drawing the trajectories according to the points.

Description

technical field [0001] The invention relates to the technical field of software engineering research, in particular to a posterior positioning data trajectory tracking method. Background technique [0002] With the rapid development of my country's economy, automobiles, as a convenient means of transportation, have entered thousands of households, and the ensuing traffic problems have become increasingly serious. Urbanization road construction has developed rapidly in cities at all levels, viaducts, tunnels , mountain tunnels, etc., have solved various traffic problems in this environment. [0003] However, the tracking of special vehicles and the management of emergency vehicles all need to adopt the posterior trajectory tracking method. Inaccurate. The trajectory of the vehicle is multi-possible. On the same road, there may be different trajectories. How to analyze these trajectories to determine the correct trajectory of the vehicle is a relatively complicated part of ve...
