Scape Feature Points Matching, obtains the feature point set of coupling；Feature point set according to coupling sets up two gunlocks
Mapping relations between two planes that picture is corresponding；Any two gunlock is set up according to mapping relations
Target corresponding relation in the scenic picture of 101.
Concrete, when gunlock 101 is multiple, set up the corresponding relation between gunlock 101: if
Visual field between two gunlocks 101 does not overlap, then it is assumed that between two gunlocks 101, it doesn't matter,
This demarcation mode is the most common；Demarcation mode i.e. can be passed through in the way of using above-mentioned automatic Calibration
Ground level is assumed to demarcate the relation between two gunlocks 101, specifically according to traditional computer vision
Method, first directly carries out scene characteristic Point matching in two gunlock pictures, according to the feature of coupling
Point set can set up the mapping relations between two planes, thus sets up the target pair in two scenic picture
Should be related to.Assume that method demarcates the relation between two gunlocks 101 by above-mentioned ground level, it is therefore an objective to
Ensure that the target corresponding relation in two scenic picture is linear；Generally, above-mentioned calibration process is permissible
Realized by the scaling method of 4 points, i.e. select four scene characteristic points to mate.On having had
After the demarcation relation stated, certain target seen in a gunlock 101, can directly correspond to another
The position at same target place in the picture of one gunlock 101.
2, gunlock 101 and the direct corresponding relation of ball machine 102 are set up: each ball machine 102 is the most attached
Belong to a gunlock 101；When ball machine 102 is attached to multiple stage gunlock 101, rob according to high priority
Account for principle and carry out the gunlock 101 control to ball machine 102；Wherein, the priority of gunlock 101 is basis
Following policy setting: nearby principle or the ball machine 102 visual angle principle of optimality.
Concrete, gunlock 101 and the direct corresponding relation of ball machine 102 belong to the rifle ball of standard and demarcate,
Rifle ball is demarcated and can be provided by Qiang Qiu equipment vendors, and some manufacturers provide automatic Calibration, i.e. use ibid
The method stating the Feature Points Matching that the foundation of the corresponding relation between multiple gunlock 101 is used, some factories
Business provides manual scaling method: i.e. by the point of artificial selected gunlock picture, (this point is it is generally required at least
3 points), then adjust ball machine 102 visual angle and make this point be in lean-with in ball machine 102 picture
Put, to complete to demarcate.
Further, each ball machine 102 is at least attached to a gunlock 101, if a ball machine 102 belongs to
In multiple stage gunlock 101, each gunlock 101 has priority difference to the control of ball machine 102.When
When multiple stage gunlock 101 controls a billiard ball machine 102 simultaneously, it then follows high priority seizes principle, and gunlock
The setting of the priority of 101 can be typically nearby principle, or the most former according to ball machine 102 visual angle
Then.Wherein, nearby principle is i.e.: gunlock 101 priority nearest apart from this ball machine 102 is the highest；Ball
The machine 102 visual angle principle of optimality is i.e.: for a target in gunlock 101, if the ball machine of association
102 can see this target by the control break visual angle of gunlock 101, such as, define target sizes
For index, the target seen by changing visual angle when ball machine 102 pixels tall in picture is the biggest,
Then the visual angle of ball machine 102 is the best, corresponding, control the gunlock 101 of the best ball machine 102 in this visual angle
Priority the highest；The priority of the gunlock 101 of the final ball machine 102 controlling optimal viewing angle is the highest.
3, demarcate the target location in gunlock 101 and ball machine 102 control the relation of parameter:
Server 103 is controlled marble forming machine 102 and is adjusted self acquisition parameter and include: server 103 is in inspection
When measuring abnormal motion target, position abnormal motion target target location in gunlock 101, according to

Position and ball machine 102 control the corresponding relation of parameter primarily to obtain in ball machine 102 visual field
Optimal viewing visual angle, is i.e. determined by level angle and the luffing angle of ball machine 102, make shooting (or
Person says candid photograph) target the most placed in the middle；It is determined by the optical magnification of ball machine 102, makes bat
The picture complete packet taking the photograph (capturing in other words) contains target, and target detail sees clearly as far as possible.
In reality, owing to target may be moved, first the position of target in gunlock 101 is amplified,
Then ball machine 102 is set according to the target location after amplifying and controls parameter, it is to avoid target moves out ball machine
102 visuals field.
In the embodiment of the present invention, all moving targets in video image can also be entered by server 103
Row detecting and tracking, concrete grammar includes:
All moving targets in server 103 positioning video image, the operation to all moving targets
Track carries out real-time tracking and analysis, and when running orbit correspondence Deviant Behavior being detected, arranges fortune
The moving target that dynamic track is corresponding is abnormal motion target, and increases the priority of abnormal motion target；
Deviant Behavior at least includes: quickly runs, drive in the wrong direction, be detained and fight；
All moving targets in server 103 positioning video image, draw at gunlock according to moving target
Position in face and the direction of motion, it is judged that whether moving target will leave current scene areas,
The most then arranging moving target is abnormal motion target, and increases the priority of abnormal motion target.
Concrete, the method for all moving targets in server 103 positioning video image specifically:
Server 103 uses Faster RCNN algorithm to carry out human detection, to position pedestrian, and at clothes
After all moving targets (such as pedestrian) in business device 103 positioning video image, use based on the degree of depth
The crowd's dividing method practised carries out crowd's dividing processing to all moving targets (such as pedestrian), and uses
Particle filter tracking algorithm the running orbit of all moving targets after dividing processing is carried out in real time with
Track and analysis.
All of moving target in the video image that gunlock 101 is gathered by server 103 has carried out excellent
First level divides, and obtains the moving target according to priority arrangement, and correspondence, server 103 then controls
All ball machines 102 of gunlock 101 correspondence are captured abnormal according to abnormal motion target priority height principle
The high-definition picture of moving target.
Server 103 control correspondence ball machine 102 captured abnormal motion target while, service
All moving targets are marked, and arrange the priority of the moving target captured in real time by device 103
It is 0；Wherein, priority is that 0 expression is not captured.
In the embodiment of the present invention, the video image that all gunlocks 101 are gathered by server 103 enters in real time
Row moving object detection and tracking, is split by human detection auxiliary crowd simultaneously.Concrete, service
The video image that all gunlocks 101 are gathered by device 103 by Faster RCNN algorithm carries out people in real time
Health check-up is surveyed, and to position pedestrian, uses crowd's dividing method based on degree of depth study to carry out crowd simultaneously and divides
Cut, with the crowd that flocks together of differentiation, prevent the crowd flocked together as a moving target,
And by particle filter tracking algorithm, the movement locus of the human body after crowd is split carry out in real time with
Track.
Server 103 is after carrying out real-time tracking to the movement locus of pedestrian, to all moving targets (i.e.
Pedestrian) it is made to determine whether to capture its high-resolution features, and according to all motions of following policy setting
The priority of target (i.e. pedestrian), wherein, the default priority of moving target is 1 (basic value),
0 expression is not captured；When the movement locus that server 103 detects human body is Deviant Behavior,
Increase the candid photograph priority of moving target corresponding to this movement locus (i.e. pedestrian), i.e. excellent give tacit consent to
Increase default value on the basis of first level basic value, and the numerical value specifically increased can be according to the fortune of human body
Dynamic track determines with the similarity of Deviant Behavior, as added 1, can add 2.
If the attached ball machine 102 of gunlock 101 needs to capture multiple moving target, then server 103
Controlling corresponding ball machine 102 to capture according to the shooting priority of moving target, i.e. preferential shooting is worked as
The moving target (i.e. pedestrian) that front priority is the highest.If all moving targets (i.e. pedestrian) is excellent
First level is all 0, then server 103 is controlled marble forming machine 102 and captured at random.
All pursuit movement targets (i.e. pedestrian) can be marked, for having grabbed by server 103
Clapping the moving target (i.e. pedestrian) of high-resolution features, directly arranging priority is 0, no longer captures.
Server 103 carries out Deviant Behavior judgement to the running orbit of moving target, when operation being detected
When track corresponds to Deviant Behavior, increase the priority of moving target corresponding to this running orbit (as excellent
First level adds 1), with the preferential candid photograph to abnormal motion target；These include extremely: quickly run,
Drive in the wrong direction, be detained for a long time, fight.
Server 103 is according to moving target position in gunlock picture and the direction of motion, it is judged that mesh
Whether mark will leave visual field, increase the priority of moving target at the scene left (as preferentially simultaneously
Level adds 1), preferentially capture so that the moving target of visual field will be left.
Ball machine 102 performs high definition snapshot task under the control of server 103: when certain moving target
