Problems solved by technology

But often for the same intersection, different road conditions will appear at different times, and different traffic signal light switch time settings are required
Therefore, under the current technical solution, because the switching time of traffic lights cannot be adjusted intelligently, it often occurs that there is little traffic in one direction and serious traffic congestion in the other direction.

[0020] Please refer to figure 1 , figure 1 A schematic block diagram of the first structure of the traffic signal light control device 10 provided by the embodiment of the present invention is shown. The traffic signal light control device 10 includes a front-end identification sub-device 100 and a back-end processing sub-device 200 .

[0021] The front-end recognition sub-device 100 is used to acquire a plurality of traffic flow images at preset time intervals, analyze each acquired traffic flow image to obtain the current traffic flow, and send the current traffic flow to the back-end processing sub-device 200 . The installation height of the front-end identification sub-device 100 mainly depends on the width of the road. The wider the road, the wider the monitoring range, and the higher the installation height will be. In common scenarios, the installation height is 5.5 to 7 meters, and the installation direction is about 30 degrees from the horizontal plane. According t...

[0032] image 3 A work flow diagram of the second structure of the traffic signal light control device 10 provided by the embodiment of the present invention is shown, and its work flow is as follows:

[0033] Step S101, the front-end recognition sub-device acquires multiple traffic flow images at preset time intervals, analyzes each acquired traffic flow image to obtain the current traffic flow, and sends the current traffic flow to the back-end processing sub-device.

[0034] In the embodiment of the present invention, multiple traffic images only need to be acquired when the traffic signal light 300 is a green light, because when the traffic signal light 300 is a red light, no matter how many vehicles pass through the intersection, they all need to wait in front of the zebra crossing, even if the road is clear , traffic images full of waiting vehicles may also appear. And when the traffic signal light 300 is a green light, if the road is more congested, the length of the t...

Embodiment approach

[0035] As an implementation manner, the method for implementing step S101 may include:

[0036] Sub-step 1 of step S101: Perform vehicle recognition on each traffic flow image to obtain the number of vehicles in each traffic flow image.

[0037] In the embodiment of the present invention, when the traffic signal light 300 is a green light, a plurality of traffic flow images are acquired according to a preset time interval. Obtain 30 traffic images.

[0038] As an implementation manner, the method for obtaining the number of vehicles in each traffic flow image may include:

[0039] First, preprocess the traffic flow image to obtain the preprocessed traffic flow image map.

[0040] In the embodiment of the present invention, the preprocessing includes processing operations such as feature extraction, image enhancement, grayscale, etc., and related algorithms used include Gaussian filtering, edge search, histogram equalization, and the like. Among them, Gaussian filtering can ...

Abstract

The invention relates to the technical field of intelligent traffic management, and provides a traffic signal lamp control device, system and method. The method comprises the steps that a front-end identification sub-device acquires multiple traffic images according to the preset time interval and analyzes each acquired traffic image so as to obtain the current traffic volume and transmit the current traffic volume to a rear-end processing sub-device; and the rear-end processing sub-device determines the light-up time of the traffic signal lamps according to the current traffic volume transmitted by the front-end identification sub-device and controls light-up of the traffic signal lamps according to the light-up time. The current traffic volume is detected in real time and the on / off timeof the traffic signal lamps is intelligently adjusted according to the current traffic volume so that the vehicles are enabled to pass according to the reasonable indication of the traffic signal lamps and the road congestion can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent traffic management, in particular to a traffic signal light control device, system and method. Background technique [0002] In the current traffic management system, the vast majority of intersections conduct traffic command through the traffic signal light system, and the vast majority of traffic signal lights are controlled through preset programs. It has become one of the important causes of traffic congestion. The switching time of existing traffic signal lights is fixed or requires manual adjustment. But often for the same intersection, different road conditions will appear at different times, and different traffic signal light switch time settings are required. Therefore, under the current technical solution, because the switching time of traffic lights cannot be adjusted intelligently, it often occurs that there is little traffic in one direction and serious traffic congestio...
