Description
Technical field
The present invention relates to technical field of video monitoring, refer in particular to a kind of gunlock, the collaborative tracing and monitoring method of ball machine.
Background technology
In safety monitoring, gunlock and ball machine are common cameras.Yet in safety monitoring, if only rely on single gunlock to be difficult to solve target occlusion and across the problems such as target Continuous Tracking of video camera.Concrete, though tracking target visual angle is limited flexibly for above-mentioned middle ball machine, and gunlock visual angle extensively but cannot tracking target.
Therefore conventionally need to realize tracing and monitoring need to use a plurality of multiple video cameras, and works in coordination with between multiple-camera, thereby reach, expands the observation scope of supervisory control system, the object of increase observation angle.Effectively improve thus the accuracy of target detection, tracking, make more application flexibly become possibility.Yet the difference due to gunlock and ball machine equipment, even if both also can there are differences therefore to aim at same object, in existing system, conventionally before collaborative tracking, need people manually both coordinates to be corrected, not only need skilled personnel to operate, have trouble and the not high problem of precision adjusted.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of and can intelligence automatically realize the collaborative tracing and monitoring method of gunlock, ball machine of mating.
The object of the present invention is achieved like this: the present invention relates to a kind of gunlock, the collaborative tracing and monitoring method of ball machine, it comprises registration flow process; Described registration flow process comprises step,
A), the initial point of gunlock is set, in the monitoring image of selected gunlock a bit as initial point;
B), writing gun machine monitoring picture, gunlock monitoring image is now captured to rear preservation;
C), record ball machine monitoring picture, ball machine monitoring image is now captured to rear preservation;
D), coordinates computed is poor, according to the gunlock monitoring image and the ball machine monitoring image calculation that capture, obtains both coordinate differences;
E), threshold decision, judge whether coordinate difference is not more than threshold value, is to forward step G to, otherwise forward step F to;
F), ball machine controls, the coordinate difference of take is rotated as stepping control marble forming machine, then returns to step C;
G), ball machine initial point arranges, it is the ball machine origin of coordinates that ball machine current location is set.
Beneficial effect of the present invention is to take into full account manual registration operation complexity in practical application, and a kind of method of intelligent autoregistration is provided, and when improving the accuracy of registration, has improved the simple type of operation, and customer experience is better.
Accompanying drawing explanation
Below in conjunction with accompanying drawing in detail concrete structure of the present invention is described in detail
Fig. 1 is the registration flow chart of the inventive method;
Fig. 2 is that the tracing and monitoring of the inventive method is controlled flow chart.
Embodiment
The invention provides a kind of method that can intelligent automatically realize gunlock, ball machine registration, take gunlock as benchmark, obtain after both pictures FEEDBACK CONTROL after comparative analysis angular deviation and adjust ball machine, thereby when improving the accuracy of registration, the simple type that has improved operation, customer experience is better.
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing 1,2 to be explained in detail.
The present invention relates to a kind of gunlock, the collaborative tracing and monitoring method of ball machine, it comprises registration flow process.
registration flow process, comprise step:
A), the initial point of gunlock is set, in the monitoring image of selected gunlock a bit as initial point;
B), writing gun machine monitoring picture, gunlock monitoring image is now captured to rear preservation;
C), record ball machine monitoring picture, ball machine monitoring image is now captured to rear preservation;
D), coordinates computed is poor, according to the gunlock monitoring image and the ball machine monitoring image calculation that capture, obtains both coordinate differences;
The account form example of this step:
Calculate gunlock picture A1 and ball machine deviation angle α: manually choose and mark A1 in target object a, rear end platform software calculates the horizontal and vertical angle of a and the A1 origin of coordinates, distinguishes very θ h1, θ v1; The position of target-marking object a in ball machine picture, rear end platform software calculates the horizontal and vertical angle of a and the ball machine picture origin of coordinates, and difference is θ h2 very, θ v2, the horizontal-shift angle [alpha] h of central point ,=θ h1-θ h2, vertical shift angle α v ,=θ v1-θ v2
E), threshold decision, judge whether coordinate difference is not more than threshold value, is to forward step G to, otherwise forward step F to;
F), ball machine controls, the coordinate difference of take is rotated as stepping control marble forming machine, then returns to step C;
G), ball machine initial point arranges, it is the ball machine origin of coordinates that ball machine current location is set.
Thus, the each ball machine of subsequent control after initial point of having set can keep ball machine initial point constant after re-powering, without configuration again.
Embodiment mono-:
Above-mentioned registration flow process comprises the step of beginning timing accumulative total registration time; Between the step e of registration flow process and step G, also comprise overtime detecting step, described overtime detecting step comprises judging whether the registration time exceed setting-up time, if exceeded, forward step G to, otherwise forward step F to.
By registration flow process is increased to timing, can from integral body, control the adjustment time of autoregistration flow process, avoid because circumstance complication reason causes repeatedly the unsuccessful problem that is absorbed in endless loop of registration.
Embodiment bis-:
In gunlock, the collaborative tracing and monitoring method of ball machine, also comprise gunlock, ball machine setting procedure.
Described
gunlock, ball machine setting procedurecomprise: gunlock is adopted to wide-angle imaging machine; The setting space of gunlock and ball machine is not more than 0.5 meter.
Common rifle ball system keeps track video monitoring system hardware components is comprised of gunlock and clipping the ball, and both can be arranged on metope, column or cross bar.Wherein gunlock requires as wide-angle imaging machine, and clipping the ball is without specific (special) requirements, the horizontal or vertical installation of the visual actual environment of rifle ball machine; Dwindling distance between the two can reduce the alignment time as far as possible, and suggestion distance does not surpass 0.5 meter.
Embodiment tri-:
