To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright embodiment is described in further detail.
As Fig. 1 parks monitoring method to show a kind of intensive vehicle peccancy provided in an embodiment of the present invention；
The method includes：
101：Obtain area video image to be detected and video image monitored area size；
102：The presetting bit scene of area video image to be detected described in three-dimensional scaling；It is described in area to be detected
Setting presetting bit scene, i.e. actual monitored region in the video image of domain, for example：Mark two parallel cars
The measurement line of diatom and a known physical length, the presetting bit scene of the three-dimensional scaling is subsequent detectors
Target sizes reference is provided and is calculated for vehicle part actual speed and foundation is provided.To occurring in monitoring section
The vehicle part in domain is positioned；
103：According to the area video image to be detected, monitor in real time vehicle part is carried out；
104：According to the vehicle part, the presetting bit scene of the three-dimensional scaling and the video image
Monitored area size, determines target vehicle and its density；
105：When the density of the target vehicle reaches predetermined threshold value for the moment, signal an alert.
It should be noted that the method also includes：
When the density of the target vehicle is less than predetermined threshold value a period of time, sound all clear.
Based on above example, the present invention expends a large amount of manpowers, captures automatically failure for manual monitoring
Intensive vehicle disorderly stops phenomenon, and detection zone monitor in real time vehicle part speed and target vehicle are treated in realization
Density.When target vehicle density reaches threshold value for the moment, it is believed that intensive vehicle peccancy parks event generation, enters
Enter alarm mode, remind traffic control personnel to arrive scene punishment in time and evacuate.When target vehicle density is less than threshold value
One, sound all clear, Restoration monitoring pattern.The concrete of monitoring method is parked below by way of intensive vehicle peccancy
The present invention is described in detail to realize flow process；Idiographic flow is as follows as shown in Figure 4：To divide into threshold value two
V is 5km/h, and duration threshold value T, threshold value one are N；
401：Obtain area video image to be detected and video image monitored area size；It is described to be detected
Area video image refers to that intensive vehicle peccancy is parked event and easily sends out region real time video image, described to be checked
Survey region can according to practical situation it needs to be determined that；Video image monitored area size refers to video
The actual range size of monitoring；
402：The presetting bit scene of area video image to be detected described in three-dimensional scaling；It is described in area to be detected
Setting presetting bit scene, i.e. actual monitored region in the video image of domain, for example：Mark two parallel cars
The measurement line of diatom and a known physical length, the presetting bit scene of the three-dimensional scaling is subsequent detectors
Target sizes reference is provided and is calculated for vehicle part actual speed and foundation is provided.To occurring in monitoring section
The vehicle part in domain is positioned；
403：According to the area video image to be detected, monitor in real time vehicle part is carried out；The vehicle
Part includes：The trapezoidal vehicle window of the tailstock, the afterbody comprising car light car plate, side vehicle window, wheel；The reality
When monitoring vehicle part by using a large amount of learning samples, by histograms of oriented gradients (Histograms
Of Oriented Gradients, abbreviation HOG) method extract target image characteristics, using engineering
Practise algorithm (for example：Using the algorithm of support vector machine) training offline inspection device.
404：According to the presetting bit scene of the vehicle part and the three-dimensional scaling, the vehicle portion is obtained
The corresponding speed of part；The vehicle part speed calculation is by initial as what is tracked using regional frame to be detected
Frame, carries out real-time tracking positioning to multiple target vehicle part using optical flow method, while carrying out same target
With confirmation, when the target and object initialization of current tracking (confirm be same target).According to target
Position in the picture can calculate target displacement in the picture, be regarded according to acquisition region to be detected
The presetting bit scene of the three-dimensional scaling of frequency, calculates tracking vehicle part speed；
405：When the speed of the vehicle part reaches two i.e. 5km/h of predetermined threshold value, by the vehicle portion
Part is recorded as target vehicle；
406：According to the quantity and video image monitored area size of the target vehicle, institute is determined
State density n of target vehicle；
407：Duration threshold value T of goal-selling vehicle；
408：Record duration t of the target vehicle；
409：When duration t of the target vehicle reaches duration threshold value T of the target vehicle,
And density n of the target vehicle is when reaching one N of predetermined threshold value, signal an alert.
410：When density n of the target vehicle is less than one N of predetermined threshold value, sound all clear.
Needs say that the detailed process of the above warning of reporting to the police and release is as follows：Institute in the present invention
State target vehicle and refer to vehicle of the vehicle part speed less than two V of threshold value.
When preset region to be detected in video image in, vehicle part be less than V, and target Continuous when
Long t reaches duration threshold value T, it is believed that target vehicle is static, when target carriage in region to be detected
Destination number accordingly increase；When target vehicle velocity is higher than V, then by target carriage in region to be detected
Quantity accordingly reduces；Tracking object matching confirm failure when (can not find at present frame tracing positional with
Track target), target (that is, was matched near target location and is found target) into the stage of investigation, was such as held
Continuous loss abandons tracking.When the vehicle part position of tracking exceeds monitored area, tracking is abandoned.According to
In region, target vehicle quantity and area size to be detected determine the density of target vehicle.When target vehicle
Density then sends alarm higher than threshold value N of setting, while continuing monitoring objective；When the target vehicle
Density be less than threshold value when all clear.
