Analysis method for identifying vehicle behavior tracks by using multiple cameras

Abstract

The invention belongs to the technical field of vehicle behavior track analysis, particularly relates to an analysis method for identifying vehicle behavior tracks by using multiple cameras, and solves the problems that the difference of display analysis of vehicle moving tracks is large, and the moving track analysis accuracy is poor. The scheme provided by the invention comprises: a track acquisition module, a vehicle track monitoring module, an analysis and identification module, and a display module. According to the invention, motion point tracks are formed through a vehicle-mounted positioning terminal on a target vehicle, the motion point tracks are matched through a model matching sub-module, and data stored in a data storage sub-module are compared and judge; driving tracks of the target vehicle are subjected to dual video recording through a camera shooting sub-module and a radar monitoring sub-module, and are sent to the data storage sub-module for caching processing. Thus, by comparing double recorded images with images recorded and transmitted by a vehicle-mounted positioning terminal on a target vehicle, driving track analysis of the target vehicle is more accurate.

Description

technical field [0001] The invention relates to the technical field of vehicle behavior track analysis, in particular to a multi-camera recognition vehicle behavior track analysis method. Background technique [0002] Vehicle trajectory display is a very important part in the Internet of Vehicles; vehicle trajectory can not only intuitively display vehicle driving information and driver's driving habits, but also intuitively display POI stop information such as vehicle refueling and maintenance, as well as driver It can be seen that the vehicle trajectory plays a very important guiding role in the analysis of vehicle driving information, driver's driving habits and road load conditions. [0003] The method of presenting the vehicle trajectory in the prior art is: draw the vehicle trajectory on the map according to the vehicle trajectory reporting point. This method usually obtains the vehicle trajectory reporting point through the vehicle or APP, so as to draw the vehicle tr...

Problems solved by technology

[0003] The method of presenting the vehicle trajectory in the prior art is: draw the vehicle trajectory on the map according to the vehicle trajectory reporting point. This method usually obtains the vehicle trajectory reporting point through the vehicle or APP, so as to draw the vehicle trajectory, and does not distinguish the vehicle during the drawing process. The parking status of the vehicle is repeatedly drawn, so that the running track of the vehicle cannot be well displayed and analyzed, and the difference value is relatively large

[0004] Therefore, there is a need for a multi-camera recognition vehicle behavior trajectory analysis method to solve the problems of large differences in the display and analysis of vehicle trajectory and poor accuracy of trajectory analysis.
