Abstract

The invention discloses a method and device for detecting vehicle flow speed, as well as a method and system for controlling traffic lights, in order to overcome the defect that the traditional vehicle flow speed detecting technology or traffic light control technology has of low accuracy or inconvenient operation and the like during acquiring vehicle flow speed. The method for detecting vehicle flow speed comprises the following steps of: acquiring video images in an acquisition range in a vehicle driving direction in real time; comparing a first video image and a second video image which are continuous in time; and obtaining vehicle flow speed in the vehicle driving direction by determining a position of a certain vehicle which is in the second video image in the first video image. Compared with the prior art, the vehicle flow speed detecting technology can quickly acquire the vehicle flow speed and reduce the realization cost and has the advantages of high detection accuracy and convenient operation.

Description

technical field [0001] The invention relates to the technical field of urban traffic, in particular to a method and device for detecting the speed of traffic flow, and a method and system for controlling traffic signal lights. Background technique [0002] With the development of social economy, urban traffic problems have attracted more and more attention. How to reasonably and effectively control the traffic flow at intersections plays an important role in ensuring the safe operation of motor vehicles and maintaining the smoothness of urban roads. It is also the most important problem to be solved in the urban traffic monitoring system. [0003] At present, the traffic flow control at most urban road intersections is realized by setting traffic lights that allow vehicles to pass directionally at intervals. Traffic lights are usually controlled by a single-chip microcomputer or PLC to realize the timing control of interval switching, and the lighting time of each color in ...
