Embodiment 1
The embodiment of the present invention provides a kind of method for recording more motor vehicles and running at a low speed illegal activities, is used for highway
In traffic control terminal, which connect with the video image recording arrangement on expressway, and control video image recording is set
It is standby that photo is tracked and shot to motor vehicle or records image.On a highway, it for the safe passing of support vehicles, keeps away
The generations of accidents such as exempt to knock into the back, there is the limitation of minimum speed per hour to the motor vehicle in highway driving, it is all to be sailed in high speed uplink
Motor vehicle except when encountering natural calamity or traffic abnormity, traveling speed per hour should all be more than or equal to the requirement of minimum speed limit.
It is provided on fastlink and minimum speed limit is answered to identify, motor vehicle is forbidden to travel lower than minimum speed per hour, however only lean on mark action,
It can not effectively forbid motor vehicle to be lower than the behavior of minimum speed limit traveling, while increase to the Difficult Law-enforcement for running at a low speed illegal activities
Degree.To run at a low speed the methods of illegal activities separated for running at a low speed to motor vehicle for the more motor vehicles that record in the embodiment of the present invention
Judicial act carries out record promptly and accurately, by running at a low speed the strong supervision of illegal activities to motor vehicle, to warn motor vehicle
Driver abides by corresponding laws and regulations, safeguards freeway traffic order.
As shown in Figure 1, this records the method that more motor vehicles run at a low speed illegal activities includes:
Step S1: starting video image recording arrangement records the original video information in monitored section.
The video recording device being arranged on starting highway carries out video monitoring, prison obtained to the section that is monitored
Video is controlled as original video information, the original foundation of illegal activities is run at a low speed as subsequent judgement motor vehicle.
Step S2: having the first image of license plate number for the every motor vehicle shooting for entering motor vehicle cog region, right
Each motor vehicle is numbered, and original video information is divided into multichannel by video separator and tracks video information, is known into vehicle
Every motor vehicle correspondence in other area tracks video information all the way, in tracking video information that the synchronous mark of number is corresponding to its
On motor vehicle.
First determine whether motor vehicle enters motor vehicle cog region, on a highway, setting motor vehicle identifies on road surface
Area takes video image recording arrangement accurately by adjusting the height and angle of video image recording arrangement
Into the image of the motor vehicle of motor vehicle cog region.
It, can be in the following ways during judging whether motor vehicle enters motor vehicle cog region:
Firstly, whether the image of monitoring motor vehicle enters in the range of the image of motor vehicle cog region, when the figure of motor vehicle
As entering in the image range of motor vehicle cog region, determine that motor vehicle enters motor vehicle cog region.If not having in motor vehicle cog region
There is the image of motor vehicle, then illustrates that no motor vehicle enters motor vehicle cog region.
As the embodiment that another can be replaced, judge whether motor vehicle enters the process of motor vehicle cog region, also
It can be such as under type: firstly, the position of detections of radar motor vehicle, installs radar scanner at crossing, obtained by radar range finding
Motor vehicle is obtained at a distance from crossing；When motor vehicle enters radar detector predeterminated position, determine that motor vehicle enters motor vehicle knowledge
Other area.
When motor vehicle enters motor vehicle cog region, the first image of motor vehicle of the shooting with license plate number, such as Fig. 2 institute
Show, when the picture or laser radar range that traffic control terminal is shot by video image recording arrangement, discovery has motor vehicle
Into after motor vehicle cog region, take pictures to the motor vehicle, the image conduct of motor vehicle of the shooting with clear license plate number
First image.The accuracy of radar range finding is higher, as shown in figure 3, through radar after motor vehicle cog region identifies image, touching
It sends out video image above-mentioned and records to shoot image.Since above-mentioned video image recording arrangement is according to the position of motor vehicle cog region
Angle and height are had adjusted, therefore in motor vehicle cog region, the image of motor vehicle can clearly be taken, especially machine
The number plate of motor-car can also clearly show that in the image of motor vehicle.
It in practice, may simultaneously include more machines in original video information when monitored sections of road vehicle is more
The driving trace of motor-car is sentenced at this point, directly carrying out running at a low speed illegal activities to more motor vehicles in original video information
It is disconnected, it is easy the interference by adjacent motor vehicle, and there may be motor-driven vehicle going trace image clarity is not high, give illegal row
For judgement increase difficulty.Therefore, the motor vehicle travelled into vehicle identification area is compiled first in embodiments of the present invention
Number, for each motor vehicle into motor vehicle cog region, multichannel will be divided by video separator in original video information
Video information is tracked, every motor vehicle correspondence into vehicle identification area tracks video information all the way, comes respectively to each machine
Motor-car is tracked, and number mark corresponding to the motor vehicle for being tracked it in tracking video information arrives the motor vehicle
On image, so that the number synchronizes the driving trace for following motor vehicle, during such motor-driven vehicle going, corresponding number is all
It can be shown in the video pictures of tracking video information, be clear that it is which motor vehicle according to number, due to number
It is to enter the sequence of motor vehicle cog region according to motor vehicle to be numbered, therefore do not need complicated data handling procedure, passes through
Number is labeled in synchronize on motor vehicle and is followed, does not need that the more time is spent to identify license plate number in vehicle identification
Code is achieved that and forms a visible unique identification for each car, reduces data processing amount.The tracking video information can
With the driving trace of the real-time tracking motor vehicle, until the motor vehicle is driven out to the monitoring range in monitored section, monitoring range can
To be set as needed, it can be certain regions for being easy to happen and running at a low speed illegal activities, for monitoring motor vehicle low speed row
Sail illegal activities.
Specifically, the tracking video information for current tracked motor vehicle is isolated from original video information, comprising:
Obtain currently tracked motor vehicle corresponding with tracking video information, it is first determined tracking video information to be separated is needed to be tracked
Motor vehicle be which motor vehicle, then from original video information, extract the corresponding video image in motor-driven vehicle going track,
Due to the difference of vehicle driving position, possible motor vehicle location in video image is not quite similar, for the ease of seeing
It examines and is currently tracked the travel situations of motor vehicle, while excluding the interference of other motor vehicles around the motor vehicle as far as possible, need pair
Extracted video image is further processed, and then amplifies video image, so that being currently tracked motor vehicle
Image be located at the central area of video image, obtain tracking video information, video image passes through after partial enlargement, this is motor-driven
The driving trace of vehicle is more clear, is conducive to observation, and is conducive to subsequent to the illegal record for running at a low speed behavior.
Step S3: in tracking video information, it is default to judge whether the travel speed of the motor vehicle of its tracking is less than
Minimum speed limit.
Judge whether the travel speed of motor vehicle is less than the minimum speed limit of section requirement, it can be according to tracking video information
The distance of the traveling of middle motor vehicle in a certain period of time determines, when the operating range of the motor vehicle in a certain period of time is small
In in the period with minimum speed limit traveling apart from when, then illustrate the current traveling speed per hour of the motor vehicle lower than minimum speed limit,
S4 is thened follow the steps, the travel situations for monitoring the motor vehicle are otherwise continued.
Step S4: when the travel speed of motor vehicle is less than preset minimum speed limit, judge the first of motor vehicle and front truck
Whether spacing is greater than default first distance threshold value.
When motor vehicle be less than preset minimum speed limit value driving process in, it is understood that there may be the case where include: in certain rain
The extreme weather conditions such as snow dense fog descend, and motor vehicle needs for driving safety to travel lower than minimum speed limit；Due to traffic accident
Etc. reasons cause traffic congestion, motor vehicle can not require to travel according to normal speed per hour；Under normal circumstances, motor vehicle is lower than minimum
Speed limit illegal running.It just needs to judge whether the first spacing of the motor vehicle and front truck is greater than normally travel on highway at this time
Default first distance threshold value then illustrate that this is motor-driven when the first spacing of itself and front truck is less than preset first distance threshold value
Vehicle is to be influenced by front truck or high-speed transit road conditions etc. and travelled lower than minimum speed limit, is not belonging to the illegal row run at a low speed at this time
To be greater than preset first distance with the first spacing of front truck under normal circumstances if the motor vehicle is influenced without extraneous factor
Threshold value, this judges that the vehicle belongs to and runs at a low speed illegal activities, and executes step S5.
Step S5: when the first spacing is greater than default first distance threshold value, reference numerals are intercepted from tracking video information
Motor vehicle be lower than minimum speed limit traveling the second image.
When the first spacing is greater than default first distance threshold value, determines that motor vehicle belongs to and run at a low speed illegal activities, due to
Illegal run at a low speed of motor vehicle is a continuous process, in order to guarantee the integrality of chain of evidence, it is therefore desirable to from tracking video
The motor vehicle that reference numerals are intercepted in information is lower than the second image of minimum speed limit traveling, at the same mark the upper moment it is corresponding when
Between, since in advance on the number mark to the motor vehicle of corresponding motor vehicle and motor-driven vehicle going will be followed, in interception machine
When the image that motor-car is illegal when running at a low speed, image of the interception with the number is as the second image.Pass through the second image in this way
The illegal activities that the motor vehicle is run at a low speed can be expressly recited, and be mapped by number and the motor vehicle, be convenient for
The motor vehicle is identified in tracking video information.
Step S6: the first image, the second image and tracking video information are sent to illegal database.
Above-mentioned first image is shot in motor vehicle cog region, and the number plate of motor vehicle can clearly be shown in the region
Show, therefore the first image can comprehensively show the image information of vehicle, the reaction of the second image is the illegal low speed row of motor vehicle
The record sailed can clearly be reflected the illegal information of the motor vehicle by the first image, the second image in this way, be simultaneously
The integrality of chain of evidence, the tracking video information of the driving trace comprising the motor vehicle in monitoring area is also one concurrent
It send, so as to form complete chain of evidence.
The method provided in an embodiment of the present invention for recording more motor vehicles and running at a low speed illegal activities, solves monitoring range
Interior real-time record any position runs at a low speed the problem of illegal activities, realizes to all motor vehicles travelled in monitored section
The record of illegal activities is run at a low speed, and the entire evidence chain of low speed illegal running can be formed without human intervention, is saved
About human resources, and then improve the treatment effeciency for running at a low speed illegal activities.
Specifically, in embodiments of the present invention, the motor vehicle for entering vehicle identification area is carried out running at a low speed illegal activities
It when record, each motor vehicle is required to isolate from original video information tracks video information all the way, therefore can generate
A large amount of tracking video information, we only focus on and retain the motor vehicle pair for running at a low speed illegal activities in fact in practice
The tracking video information answered and the first image for having license plate number, therefore as further embodiment, as shown in figure 4, should
Record the method that more motor vehicles run at a low speed illegal activities, further includes:
Step S7: when the first spacing is greater than default first distance threshold value, judge that the second spacing of motor vehicle and rear car is
It is no to be less than default second distance threshold value.
When the first spacing of motor vehicle and front truck is greater than first distance threshold value, i.e., the motor vehicle is in illegal and runs at a low speed
When, at this point, the motor vehicle is in low-speed running state, it is easy to which the normally travel for influencing rear car be easy to cause and delays unloading, when the machine
The rear car of motor-car when driving, is also easy to knock into the back Deng traffic accidents with higher speed per hour, in order to judge the illegal low speed of motor vehicle
Whether traveling impacts to rear car, needs to judge whether the second spacing of the motor vehicle and rear car is less than preset second distance
Threshold value illustrates the motor vehicle not to the row of rear car when motor vehicle and the second spacing of rear car are greater than default second distance threshold value
It sails and impacts, it is no to then follow the steps S8.
Step S8: when motor vehicle and the second spacing of rear car are less than default second distance threshold value, from tracking video information
Interception includes the third image of motor vehicle and rear car.
When motor vehicle and the spacing of rear car are less than default second distance threshold value, illustrate the motor vehicle to the machine of behind
Motor-car, which causes, delays unloading, and influences the normally travel of rear car, causes bigger traffic impact, needs from recording the motor-driven vehicle going
The third image comprising motor vehicle and rear car is obtained out in the tracking video information of track, convenient for the acquisition of subsequent illegal evidence,
And it can be convenient high-speed transit administrative department to the real time monitoring of highway, interception includes the third figure of motor vehicle and rear car
As after, step S9 is executed.
Step S9: third image is sent to illegal database.
Third image comprising motor vehicle and rear car is sent to illegal database, it can adopting in order to subsequent illegal evidence
Collection, and can be convenient high-speed transit administrative department to the real time monitoring of highway.
As other further embodiments, as shown in figure 5, this, which records more motor vehicles, runs at a low speed illegal activities
Method, further includes:
Step S10: when motor vehicle enters monitored section, the speed of real-time monitoring motor vehicle, the first spacing, the second vehicle
Away from, and speed, the first spacing, the second spacing are marked in real time in the tracking video information of motor vehicle.
After when motor vehicle enters monitored section, the travel speed of motor vehicle, the vehicle with the spacing of front truck and with rear car
Away from being all to judge the whether illegal foundation run at a low speed of motor vehicle, it is therefore desirable to speed to motor vehicle and with front truck and rear car
Spacing is monitored in real time, above- mentioned information is marked in real time in tracking video information, can be quasi- by tracking video information
True shows that the illegal of the motor vehicle runs at a low speed behavior, facilitates the subsequent access to illegal activities evidence.
As other further embodiments, as shown in fig. 6, this, which records more motor vehicles, runs at a low speed illegal activities
Method, further includes:
Step S11: judge whether motor vehicle is driven out to monitoring range.Monitoring range can be from motor vehicle cog region to minimum
The end position of speed limit, so as to accurately identify the illegal behavior run at a low speed of motor vehicle.When motor vehicle is driven out to monitoring model
It encloses, executes step S9, otherwise continue the driving trace of motor vehicle in monitoring tracking video information.
Step S12: after motor vehicle is driven out to monitoring range, the second image is judged whether there is.
If the illegal behavior run at a low speed has occurred in the motor vehicle, the second figure can be generated in illegal run at a low speed
Picture, so if generating the second image, then there are the illegal behaviors run at a low speed for explanation, if said without the second image
It is bright that the illegal behavior run at a low speed is not present.Second image if it exists thens follow the steps S13, no to then follow the steps S14.
Step S13: when there are the second image, then tracking video information and the first image are stored.
If motor vehicle there are the illegal behavior run at a low speed, needs the tracking video information that separator is isolated
Subsequent query is convenient in storage.
Step S14: when the second image is not present, then tracking video information and the first image are deleted.
If there is no the second image, then illustrate motor vehicle do not have it is illegal run at a low speed, Gu do not deposited in the monitoring area
In the illegal behavior run at a low speed.The corresponding tracking video information of the vehicle in the monitoring area does not have to retain, therefore can delete
Except the tracking video information, to save memory space, the utilization efficiency of storage equipment is improved.The passage of vehicle on expressway
Amount is very big, if the data to all vehicles all retain, needs to occupy very big memory space, and traffic police is artificial
Illegal information is looked for from these tracking video informations, it is also desirable to be devoted a tremendous amount of time, be entered in this programme in motor vehicle
It is monitored in monitoring range, the corresponding tracking video information of the vehicle is obtained, after being driven out to monitoring range, by illegal information
Judgement, obtain the motor vehicle with the presence or absence of illegal information, if there is no if, just delete these tracking video informations, such as
If fruit exists, these tracking video informations are uploaded to monitoring center and stored, the schematic diagram of the process as shown in figure 3,
In the server of monitoring center, the image data that can be stored by host computer preview can also be in data center or reception
Platform is further processed data, provides more traffic data informations.Therefore it does not need to deposit in the monitor terminal at crossing
Too many garbage is stored up, the utilization rate of resource is improved, also saves the time of the manual identified tracking video information of traffic police,
Automatic discovery illegal vehicle is realized, and forms complete chain of evidence, provides more information for traffic administration.
As another optional embodiment, in order to further increase the precision of identification, can also include: motor vehicle into
After entering motor vehicle cog region, number plate identification is carried out to motor vehicle；Since the image of motor vehicle in motor vehicle cog region can be clear
Chu takes, and number plate can be clearly seen, therefore identification license plate is more accurate in the area, reduces automotive number plate
Due to problem unrecognized caused by being blocked.Then, on the number plate mark to the image of motor vehicle that will identify that, number plate
Synchronize the driving trace for following motor vehicle.It, can also its clear number plate in time in this way, no matter the motor-driven vehicle going is to any position
Information, convenient for real time monitoring.
It, can also in step s 6, by the first image, the second image and the number pair as other optional embodiments
During the tracking video information answered is sent to illegal database, number plate identification can be carried out according to the first image；Then will
The number plate information that identifies while sending illegal database.In the embodiment, can also before the step of in without number
Board identification, but when motor vehicle generation is illegal run at a low speed behavior after, then identified by the first image taken motor-driven
The number plate of vehicle, the number plate that then will identify that are sent collectively to illegal database.In the program, it can enter to avoid in motor vehicle
