Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0038] The first embodiment of the present invention provides a vehicle trajectory analysis method, see figure 1 , the method includes:

[0039] Step S1, obtaining multiple vehicle positions reported by the vehicle to be analyzed at different times;

[0040] Step S2, performing merging processing on the plurality of vehicle positions, merging two vehicle positions whose distance is smaller than a first preset value into one vehicle position;

[0041] Step S3, generating vehicle trajectories according to the respective vehicle positions obtained after the merging process;

[0042] Step S4, displaying the generated vehicle trajectory.

[0043] In this met...

Abstract

The invention relates to the technical field of on-board equipment, in particular to a vehicle trajectory analysis method and device. The method comprises the following steps of acquiring multiple vehicle positions reported by a vehicle to be analyzed at different moments; merging the multiple vehicle positions, and merging two vehicle positions with the distance being smaller than a first preset value into one vehicle position; generating a vehicle trajectory according to each vehicle position obtained through merging; displaying the generated vehicle trajectory. Therefore, repetitive point drawing can be avoided, and users can more clearly know the vehicle trajectory of the vehicle to be analyzed.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a vehicle trajectory analysis method and device. Background technique [0002] Vehicle trajectory display is a very important part in the Internet of Vehicles. The vehicle trajectory can not only intuitively display the vehicle driving information and the driver's driving habits, but also intuitively display the POI stop information such as vehicle refueling and maintenance, and the driver's preference for high-speed or national highways while driving. It can be seen that the vehicle trajectory has a very important guiding role in the analysis of vehicle driving information, driver's driving habits and road load conditions. [0003] In the prior art, a method for displaying a vehicle trajectory is as follows: drawing the vehicle trajectory on a map according to the reported points of the vehicle trajectory. This method usually obtains the vehicle trajectory reporting ...
