Description
Technical field
The invention belongs to traffic monitoring and intelligent video analysis field, and in particular to a kind of to control traffic to believe by flow of the people
The method of number machine.
Background technology
Intelligent video analysis refers to extract useful information from vision signal by practical computer technology, and to video
Content carries out real-time intelligent analysis.Its essence is process of the computer to extraction and the understanding of " useful content " in video, this
The key of process is that computer is analyzed the particular event occurred in video scene or the specific behavior of target, understood, known
Not and take some measures.
With the increase of public transport awareness of safety, traffic surveillance and control system has achieved significant progress, and has obtained wide
General application.But most video monitoring systems do not possess the ability of intellectual analysis video content, all prisons also at present
Controlling video must rely on manpower to handle.However, the video that numerous camera shootings is monitored by manpower has great limitation
Property：First, the energy of people is limited, it is impossible to pays close attention to video information at any time；Second, amount of video information is huge, same time showing exists
The camera lens of video wall is limited, often misses some information to merit attention；Third, video information is difficult to obtain comprehensive analysis, hold
Easily cause and the mistake of the state of affairs is estimated.Therefore substantial amounts of video in fact simply serves the effect of " inquiring about afterwards ", does not send out
Wave the maximum utility of information process-.
, can be according to vehicle flowrate on road and flow of the people by using intelligent video analysis technology in traffic surveillance and control system
The control of traffic signals is carried out, effectively improves traffic efficiency.
The content of the invention
The technical problem to be solved of the present invention is to provide a kind of method that traffic signaling equipment is controlled by flow of the people,
The signal lamp opening and closing of traffic signal controlling machine can be started, effectively lift the traffic efficiency of road.
The present invention solves above-mentioned technical problem using following technical scheme：One kind controls traffic signaling equipment by flow of the people
Method, comprise the steps：
Step 1：By the vision signal of data collecting module collected flow of the people, the data acquisition module is using shooting
Head；
Step 2：Traffic video stream is decoded data conversion module and transcoding；
Step 4：Video data is streamed to CPU module；
Step 5：CPU module calculates the area ratio of whole video shared by people taken in each frame video,
Draw minimum area ratio, middle area ratio and maximum area ratio；
Step 6：By the flow of the people before and after the time point where area ratio among display module observation, a conjunction is found out
The time point of suitable conversion traffic signaling equipment signal；
Step 7：At the time point for the conversion traffic signaling equipment signal found out according to step 6, pass through operation module, input inquiry
Instruction, finds area ratio value corresponding to these time points, is the flow of the people threshold values for controlling traffic signaling equipment, and the stream of people
Measure threshold values storage in a storage module；
Step 8：Central processing unit is connected to video data stream and calculates the face of whole video shared by taken people every time
Product ratio, the value being calculated contrasted with the threshold values, if greater than the threshold values, then controls the people of the camera position
The traffic signaling equipment on trade gives a green light, if close to the threshold values, controls the traffic on the pavement of the camera position
The bright orange lamp of semaphore, if less than the threshold values, then the traffic signaling equipment on the pavement of the camera position is controlled to send out a warning.
Specifically, also include between step 2 and step 4：
Step 3：Video data stream is further subjected to data compression by data compressing module.
Specifically, the traffic video data that data conversion module is decoded to traffic video stream and transcoding is AVI format
Stream.
Specifically, in the step 5, the data of 24 hours are calculated.
Specifically, the camera of the monitoring flow of the people is arranged on the shelf where traffic lights, and camera
Towards the direction of crossing.
The advantage of the invention is that：By the collection of big data, statistics, calculating, flow of the people threshold values is drawn, passes through the calculating
The threshold values gone out, start the signal lamp opening and closing of traffic signal controlling machine, effectively lift the traffic efficiency of road.
Brief description of the drawings
Fig. 1 is a kind of composition frame chart of stream of people's amount control system of the present invention.
Embodiment
