Description
Technical field
The present invention relates to traffic management technology, specially a kind of Intelligent Dynamic timing traffic based on vehicle flowrate video detection
Lamp system.
Background technology
In modern city, since existing crossing traffic lamp is largely using the control of fixed timing and timing at times
Scheme has the shortcomings that timing immobilization, be easy to cause the few passage direction green light of wagon flow without vehicle is current or vehicle flowrate more than it is logical
Line direction green time is short, causes traffic congestion, while generating a large amount of automobile exhaust pollution, and consumes the energy.
Invention content
The shortcomings that in order to overcome the prior art to refer to, the present invention provide a kind of Intelligent Dynamic based on vehicle flowrate video detection
Timing traffic light systems, when the vehicle that can not be handled on some passage direction to solve to propose in above-mentioned background waits for traffic lights
Between longer situation.
The present invention solve technical solution that its technical problem uses for：A kind of Intelligent Dynamic based on vehicle flowrate video detection
Timing traffic light systems, including video traffic flow detection module, microcontroller and traffic grade module, the video traffic stream
Amount detection module includes the video camera, video frequency collection card and image processing equipment of data connection successively, and the video is taken the photograph
For camera for being arranged above road, real-time video detects road traffic condition, the video camera and video frequency collection card number
According to connection, the video frequency collection card obtains the vision signal of the video camera machine testing road traffic flow, at described image
Vision signal is converted into digital picture by reason equipment, and described image processing equipment is connect with single-chip data, the microcontroller control
System connects the traffic grade module, and the traffic grade module includes timing display and traffic lights.
Preferably, the timing display and traffic lights control working condition by chip microcontroller.
The beneficial effects of the invention are as follows：The design has abandoned the traffic grade of traditional fixation timing and timing at times
Scheme can detect vehicle flowrate in real time using video camera, by the information of vehicle flowrate of feedback, realize that the intelligence of traffic lights is dynamic
State timing can be good at coping with conventional traffic crossing there are the few passage direction green lights of wagon flow and is current or vehicle flowrate is more without vehicle
Passage direction traffic congestion phenomenon caused by due to green time is short.

The present invention is further detailed below in conjunction with the accompanying drawings.
A kind of Intelligent Dynamic timing traffic light systems based on vehicle flowrate video detection, as shown in Figure 1, including video traffic
Flow detection module 4, microcontroller 5 and traffic grade module 6, the video traffic flow detection module 4 includes several successively
According to the video camera 1, video frequency collection card 2 and image processing equipment 3 of connection, the video camera 1 is for being arranged in road
Top, real-time video detect road traffic condition, and the video camera 1 and 2 data connection of video frequency collection card, the video are adopted
Truck 2 obtains the vision signal that the video camera 1 detects road traffic flow, and described image processing equipment 3 is by video figure
As being converted into digital picture, described image processing equipment 3 and 5 data connection of microcontroller, the control of the microcontroller 5 connects the friendship
Logical lamp control module 6, the traffic grade module 6 includes timing display 7 and traffic lights 8；Microcontroller 5 is according to the figure
As the digital picture situation for the road traffic flow that processing equipment 3 is transmitted, control timing display 7 and traffic lights 8 are realized not
Same working condition.
Operation principle：When having vehicle by each road, it is placed in 1 real-time video of the video camera detection road above road
Road traffic obtains vision signal by video frequency collection card 2 and detects road traffic flow, and image processing equipment 3 believes video
It number is converted into digital picture, exports information of vehicles.Microcontroller 5 receives information of vehicles and realizes timing display 7 and traffic lights 8
Intelligent Dynamic timing.
Refering to Fig. 2 to Fig. 4, the present invention has used video to detect the technology of vehicle flowrate in real time, is regarded by being set up on track
Frequency video camera 2 obtains vision signal using video frequency collection card 3 and detects road traffic flow, then defined virtually on road
Detection line.When vehicle is by a virtual detection line, the gray value of pixel can occur significantly to change on virtual detection line, lead to
It crosses and the identification of grey scale pixel value variation on detection virtual detection line is counted.Finally by image processing equipment 3 to video
The pretreatment of image, the algebraic operation of image, the segmentation of the threshold process of image, the Morphological scale-space of bianry image and vehicle
Obtain the parameter of vehicle flowrate.
The traffic grade module 6 of the present invention is connected with microcontroller 5, and microcontroller 5 receives what image processing equipment 3 obtained
Vehicle flowrate parameter is analyzed, and realizes the Intelligent Dynamic timing of traffic light control system.
As described above, only presently preferred embodiments of the present invention, when cannot be limited the scope of implementation of the present invention with this,
All still belong to the present invention according to simple equivalent changes and modifications made by scope of the present invention patent and invention description content generally
In the range of patent covers.
