Embodiment Construction

[0038] The method of intelligent traffic management and route information push based on monocular vision proposed by the present invention includes four stages in its implementation. The so-called monocular vision is to use only one camera to complete the positioning work. It has the characteristics of being easy to use and widely applicable. , there is no need to solve the matching problem of the optimal distance between the two cameras and the feature points in the stereo vision, and it will not produce a large distortion like the omnidirectional vision sensor. In the present invention, the user is also the current vehicle or the current driving vehicle. Car refers to the vehicle in front of the user, such as figure 1 Shown:

[0039] figure 1 The middle node S1 describes the first stage, which mainly completes the data collection of traffic information. Including obtaining the real-time information of the current vehicle, obtaining the information of the intersection monit...

Abstract

The invention provides a monocular-vision-based intelligent traffic management and route information push method ad system. The method comprises: traffic information data of a user are obtained, a traffic vehicle distribution pool is generated, the traffic information data are analyzed at intervals, the analyzed data are compared with data of the traffic vehicle distribution pool at a previous time to obtain data of the traffic vehicle distribution pool again, and an abnormal situation is reported; a current position of the user is determined, route information push is carried out on the user based on the current position, and a shortest route and a route with minimum time are provided by using a congestion state provided by the traffic vehicle distribution pool at a current time as a reference according to starting point and destination positions inputted by the user; when a navigation function is used during the user driving process, pushed route information is updated at any time according a current road condition information change and the current position of the user. According to the invention, information of the user position and the vehicle speed can be obtained in real time; the user can be restricted; and a phenomenon of breaking a traffic rule by a user can be avoided.

Description

technical field [0001] The invention relates to the field of intelligent traffic management and route information service, in particular to a method and system for intelligent traffic management and route information push based on monocular vision. Background technique [0002] With the development of the economy, the improvement of people's living standards, the rapid development of urbanization and motorization has brought many problems to urban traffic. Increased congestion, serious pollution, frequent accidents and other phenomena have seriously affected people's life and work. Building an ecological city through an intelligent system and realizing a green transportation system are the key technologies and development directions to improve the travel environment, make full use of transportation facilities, and improve the service level of the transportation system. At this stage, my country's urban construction is in the period of great development of old city reconstru...
