Traffic state identification method based on binocular camera

Abstract

The invention discloses a traffic state identification method based on a binocular camera, and belongs to the technical field of intelligent traffic guidance. The method comprises the following threesteps: (1) establishing a reference data a, determining a traffic state clustering center, and transmitting and storing a traffic state clustering center matrix to the information board of each traffic section through a traffic system management control platform, and b, setting a road background image, and sending the road background image to the information board of a corresponding traffic intersection through the traffic system management control platform; (2) calculating relevant parameters for determining a road traffic state: a, calculating a road space occupation rate S, and b, calculating two parameters of vehicle flow q and vehicle speed v; and (3) traffic state identification: judging to which traffic state each traffic section belongs through the two parameters of the vehicle flow q and the vehicle speed v of each traffic section by the information board, and issuing the two parameters. The method can provide real-time traffic conditions for travelers, and road resourcesare fully and reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic guidance. Background technique [0002] With the rapid development of economy and society, transportation is also developing at a high speed, and the problem of urban traffic congestion is becoming more and more serious, which not only increases people's travel time and travel costs, but also causes large economic losses. Using road widening to solve the problem is costly and takes a long time, and there will be more and more vehicles, which cannot effectively solve the problem. How to take effective measures to fully and effectively use the existing road resources, relieve traffic pressure to the greatest extent, and promote social and economic development is an urgent problem to be solved at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a traffic state recognition method based on a binocular camera. This metho...
