Embodiment 1

[0062] A traffic signal control method based on visual recognition of associated intersections, such as figure 1 shown, including the following steps:

[0063] (1) Acquisition of the target intersection: Obtain the map information where the target intersection is located, determine all lane information and control signals of the target intersection in each direction, and obtain the associated intersection of the target intersection; the associated intersection has a lane directly with the target intersection connected intersection. The target intersection, such as figure 2 As shown in , it is an intersection in the downtown area of ​​a certain city, and three associated intersections connected with it.

[0064] The lane information includes road length, road width, lane width, lane attributes, stop line position, intersection width, and intersection length information; the lane attributes include straight ahead, left turn, straight left turn, and U-turn.

[0065] (2) Obtai...

Abstract

The invention discloses a traffic signal light control method and system based on visual recognition of correlated intersections. The method includes the steps: (1) acquiring a target intersection; (2) acquiring camera video streams of the target intersection and correlated intersections, and processing the camera video streams into image sequence correlated with a time axis; (3) performing visualrecognition of the target intersection; (4) performing visual recognition of correlated intersections; (5) performing non-visual area simulation; (6) performing decision data acquisition; (7) obtaining decision control signals. The system includes a target intersection camera, a correlated intersection camera, an image data processing module, an analog module, a decision module, and a signal synchronization module. The method and system provided by the invention improve the traffic efficiency of the intersection as a whole, reduce the waiting time of the vehicle, have good adaptability, and have scalability.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and more specifically relates to a traffic signal light control method and system based on visual recognition of associated intersections. Background technique [0002] With the rapid urbanization process, the number of urban car ownership is gradually increasing, which has brought great pressure to urban traffic. The traditional static time allocation scheme based on statistical methods cannot be adaptively adjusted according to real-time traffic conditions, which may easily cause problems such as empty green lights, congestion, etc., and low traffic efficiency. In order to improve the traffic efficiency at intersections through real-time dynamic signal light control, there have been many published inventions or documents to solve this problem through various technical approaches. [0003] At present, the adaptive signal light adjustment method based on the geomagnetic induction coil i...
