Abstract

The invention discloses a method of controlling a traffic signal controller through a vehicle flow. The method comprises steps: a video signal for the vehicle flow is acquired through a data acquisition module; a traffic video flow is decoded and transcoded; a video data flow is further subjected to data compression through a data compression module; the video data flow is transmitted to a central processor module; the central processor module calculates an area ratio of a vehicle photographed in each frame of video to the overall video, and the minimal area ratio, the middle area ratio and the maximal area ratio are obtained; vehicle flows before and after a time point when the middle area ratio is are observed through a display module, and a time point for converting a signal of the traffic signal controller is found out; the area ratio values corresponding to the time points are found out; and the obtained values are compared with a threshold. The method of the invention has the advantages that through acquisition, counting and calculating of big data, the vehicle flow threshold is obtained, on and off of a signal lamp of the traffic signal controller are started through the calculated threshold, and the road passing efficiency is effectively enhanced.

Description

A kind of method being controlled traffic signaling equipment by vehicle flowrate
Technical field
The invention belongs to traffic monitoring and intelligent video analysis field, be specifically related to a kind of method being controlled traffic signaling equipment by vehicle flowrate.
Background technology
Intelligent video analysis refers to and from vision signal, extracts useful information by practical analysis machine technology, and carries out real-time intelligent analysis to video content.Its essence be computing machine to the extraction of " useful content " in video and the process of understanding, the key of this process is that the specific behavior of computing machine to the particular event occurred in video scene or target is analyzed, understands, identified and take some measure.
Along with the increase of public transport awareness of safety, traffic surveillance and control system achieves significant progress, and is widely used.But current most video monitoring system does not also possess the ability of intellectual analysis video content, and all monitor videos must rely on manpower process.But the video relying on manpower to monitor the shooting of numerous camera has significant limitation: one is that the energy of people is limited, can not pay close attention to video information at any time; Two is that amount of video information is huge, and same time showing is limited at the camera lens of video wall, often misses the information that some merit attention; Three is that video information is difficult to comprehensively be analyzed, and easily causes and estimates the mistake of the state of affairs.Therefore the effect that a large amount of videos in fact just serves " inquiring about " afterwards, does not play the maximum utility of information process-.
By using intelligent video analysis technology in traffic surveillance and control system, the control of traffic signals can be carried out according to vehicle flowrate on road and flow of the people, effectively improve traffic efficiency.
Summary of the invention
Technical matters to be solved of the present invention is to provide a kind of method being controlled traffic signaling equipment by vehicle flowrate, can start the signal lamp opening and closing of traffic signal controlling machine, effectively promote the traffic efficiency of road.
The present invention solves the problems of the technologies described above by the following technical solutions: a kind of method being controlled traffic signaling equipment by vehicle flowrate, is comprised the steps:
Step 1: by the vision signal of data collecting module collected vehicle flowrate;
Step 2: data conversion module is decoded and transcoding to traffic video stream;
Step 3: video data stream is carried out data compression further by data compressing module;
Step 4: the video data stream through overcompression is sent to CPU module;
Step 5: CPU module calculates the area ratio of whole video shared by vehicle taken in each frame video, calculates the data of 24 hours, draws minimum area ratio, middle area ratio and maximum area ratio;
Step 6: in the middle of being observed by display module area ratio place time point before and after vehicle flowrate, find out the time point of a suitable conversion traffic signaling equipment signal;
Step 7: according to the time point of the conversion traffic signaling equipment signal that step 6 is found out, by operational module, input inquiry instruction, finds the area ratio value that these time points are corresponding, namely be the vehicle flowrate threshold values controlling traffic signaling equipment, and this vehicle flowrate threshold values is stored in a storage module;
Step 8: the area ratio of whole video shared by the vehicle of video data stream also taken by calculating received by central processing unit at every turn, the value calculated and this threshold values contrast, if be greater than this threshold values, the traffic signaling equipment then controlling the track of this camera position gives a green light, if close to this threshold values, then control the bright orange lamp of traffic signaling equipment in the track of this camera position, if be less than this threshold values, then the traffic signaling equipment controlling the track of this camera position sends out a warning.
Concrete, data conversion module is decoded to traffic video stream and transcoding is the traffic video data stream of AVI form.
Concrete, described data acquisition module adopts camera.
Concrete, the camera of monitoring vehicle flowrate is arranged on the erecting frame above the track being positioned at traffic intersection.
Concrete, have a camera above each track at least.
The invention has the advantages that: by the collection of large data, statistics, calculating, draw vehicle flowrate threshold values, the threshold values calculated by this, start the signal lamp opening and closing of traffic signal controlling machine, effectively promote the traffic efficiency of road.
