Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that specific embodiment described herein is not used to limit only to explain the present invention
The fixed present invention.
As shown in figure 1, the system function module figure of the present invention, it includes information centre, unmanned aerial vehicle platform and communication module；
The license plate number of unmanned aerial vehicle platform receive information center transmission and the geographical coverage area for needing unmanned plane to go on patrol, pass through Car license recognition
Technology and visual pursuit technology carry out locating and tracking to escape vehicle, and positional information is sent to communication using GPS positioning technology
Module, and by TCP/IP forms real-time Transmission to information centre, information centre sends it to traffic control department, traffic control department adjusts
Escape vehicle is intercepted with suitable police strength.
Described information carries out information interchange associative operation centrally through being wirelessly transferred with outside；Information centre escapes for transmission
Vehicle license plate number of escaping receives the location coordinate information of communication module transmission, sends it to traffic control department to unmanned aerial vehicle platform.
The unmanned aerial vehicle platform includes automatic car plate identification module, target tracking module and locating module；
Automatic car plate identification module identifies the target carriage of mobile cart on road using license plate recognition technology by camera
Board；
Target tracking module includes flight module, power supply module and collision prevention module, for according to the car plate identified, controlling nobody
Target following is realized in machine flight movement；
Locating module sends positional information to communication module by GPS positioning technology.
Communication module is mounted on unmanned aerial vehicle platform, for target position information to be sent into information centre.
Fig. 2 is present system flow chart, first, and the escape vehicle license plate number for needing to follow the trail of is sent to nothing by information centre
Automatic car plate identification module is opened after people's machine platform, unmanned plane receive information and makes an inspection tour the upper motor-car of road, target carriage is recognized
Bridge queen's unmanned plane is flown using target tracking module lock onto target vehicle, and using being mounted in communication module on unmanned plane by position
Confidence breath is real-time transmitted to information centre, and information centre, which receives, to be sent it to the police and chased after information；
If chasing success, feedback message sends this link of order fulfillment to unmanned plane or connect to information centre, information centre
And send next escape vehicle license plate number for needing to follow the trail of, otherwise send the instruction for continuing to track time vehicle to unmanned plane until grabbing
Catch success；
If unidentified then returned to target license plate re-starts second step until identifying that target license plate carries out the 3rd step again.
Automatic car plate identification process figure as shown in Figure 3, automatic Car license recognition is extracted first with image processing techniques
One or some suspected license plate areas, then pass through SVM（Support Vector Machine SVMs）To distinguish
Going out these regions, which is only real car plate, or is not car plate, if a region is car plate position, then
Then OCR is passed through（Optical Character Recognition optical character identifications）Technology identifies specific car plate
Number.
Target tracker schematic diagram as shown in Figure 4, is based on control platform after the characteristic value of target license plate is identified
Instruction enter target following pattern；
Target following technology selects " intelligent visions of FOLLOW SNAP 1.0 are followed " technology, and intelligent vision follows technology to be calculating
Machine vision（CV）One kind of technology, passes through the kinematic parameter to following target, such as position, speed, acceleration and movement locus
Characteristic is extracted and calculated, and then position, the movement tendency to aircraft etc. is controlled, final to realize to enter target
The technology that row is followed；
Intelligent vision follows technology to be that extraction and calculating based on pixel characteristic data are realized；In target moving process, calculate
The former frame and next frame of method meeting Auto-matching image, compare before and after being carried out to selected target region and judge and then control
Aircraft is followed；The deformation trace that algorithm can also have occurred and that according to target carries out fault-tolerant and prediction, to improve computing
As a result reliability and kinematic accuracy.In crowd, aircraft can also accurately identify target signature and be followed, without
It is offset in other targets, even if the target leaves picture, can be still recognized when it is again introduced into by aircraft.
After traffic control department, which transfers suitable police strength, to be intercepted on the route that target is advanced, information centre needs to send
Instruct and terminate the tracking of this target to unmanned aerial vehicle platform and enter in next target identification tracing task.
A kind of escape vehicle recognition and tracking system based on unmanned plane proposed by the present invention, can make up tradition at present fixed
Video camera is implemented to chase the deficiency such as time-consuming, poorly efficient of processing to escape vehicle, the characteristics of with quick response, maneuverability, carries
High vehicle supervision department is to the disposal ability of escape vehicle and the efficiency on duty of traffic police.
