Problems solved by technology

[0005] This application provides a method for obtaining real-time travel trajectory of vehicles based on video data of passing vehicles. By constructing the optimal adjacency matrix of the urban road network, analyzing and processing the video data of passing vehicles, and comparing and judging vehicle driving information and historical travel chains, To a certain extent, it can solve the problem that the vehicle cannot obtain the travel trajectory due to the lack of GPS equipment, the dynamic update of the vehicle travel chain cannot be realized, and the calculation of the travel chain consumes too much system resources.

Abstract

The present application relates to the technical field of intelligent traffic control, in particular, to a method for acquiring real-time travel trajectories of vehicles based on passing video data. To a certain extent, it can solve the problem that the vehicle cannot obtain the travel trajectory due to the lack of GPS equipment, the dynamic update of the vehicle travel chain cannot be realized, and the calculation of the travel chain consumes too much system resources. The method includes: constructing the optimal adjacency matrix of the road network according to the city's road network topology information; analyzing the passing video data from the detection point to obtain the vehicle driving information, the vehicle driving information includes the capture time, the capture point , the license plate number; based on the optimal adjacency matrix, comparing and determining the travel information of the vehicle with the historical travel chain of the vehicle, and constructing the real-time travel trajectory of the vehicle.

Description

technical field [0001] The present application relates to the technical field of intelligent traffic control, in particular, to a method for acquiring real-time travel trajectories of vehicles based on passing video data. Background technique [0002] The real-time travel trajectory of the vehicle is a big data product derived from the popularization and application of electronic police and bayonet equipment in the transportation system. When the vehicle passes through the detection equipment set up at the intersection of the city, its passing data can be recorded. Passing vehicle data contains rich spatio-temporal information. By analyzing the passing vehicle data, we can mine user travel patterns and study the characteristics of micro-traffic flow news business, which is conducive to improving the level of urban traffic planning and management, reducing urban road congestion, and improving traffic flow. system operating efficiency. [0003] In some implementations of obt...
