Brief description of the drawings
Fig. 1 is the flow chart of the present invention；
Fig. 2 is the block diagram of the present invention.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
The first embodiment of the present invention, which is related to, a kind of can recognize the monitoring head of any video camera motorized zoom lenses
Control method, as shown in figure 1, comprising the following steps：(1) the automatic zoom drive scope for obtaining video camera motorized zoom lenses；
(2) video camera is associated with monitoring head according to zoom drive scope so that the focal length of video camera motorized zoom lenses exists
During amplification, monitoring head slows, and the focal length of video camera motorized zoom lenses is when reducing, and the speed of monitoring head becomes
It hurry up.
When obtaining the zoom drive scope of camera lens automatically, adopt with the following method：Pass through the detection on control panel
Switch makes the camera lens for the video camera being connected with control panel carry out autozoom action, after the completion of autozoom action, control panel
Read the zoom drive scope of camera lens.
Specifically, switched by Pen-down detection, control panel sends control signal to video camera so that video camera is carried out certainly
Dynamic zoom action, autozoom action can change to focal length automatically from short focus, can also change to short focus automatically from focal length, treat certainly
After the completion of dynamic zoom action, focal length when control panel reads focal length when camera lens have just started zoom and stops zoom, from
And the zooming range of camera lens is obtained, control panel can also record the time and stopping when camera lens have just started zoom
Time during zoom, so as to obtain the functional relation of zooming range and time.
The concrete mode of the step (2) is as follows：Zoom drive scope to acquisition is implemented to be calculated as below：Zoom magnification=
Maximum focal length/minimum focus, zoom magnification is precisely associated with monitoring head speed, and obtained connecting relation is head speed
Degree is inversely proportional with zoom magnification, can access the speed of focal length one monitoring head of correspondence of a camera lens, the connection
The speed for connecing relation corresponding monitoring head when the focal length of camera lens is maximum is most slow, when the focal length of camera lens is minimum
When corresponding monitoring head it is fastest.Afterwards, control panel can according to the connecting relation control monitoring head up and down and
The speed moved left and right so that the focal length of camera lens is in amplification, and monitoring head slows, Jiao of camera lens
Away from when reducing, the speed of monitoring head accelerates.
Second embodiment of the present invention be related to it is a kind of can recognize the monitoring head control device of any camera lens,
As shown in Fig. 2 including control panel, the control panel is connected with video camera, the control panel includes automatic acquisition module and association
Module, the automatic acquisition module is used for the zoom drive scope for obtaining camera lens automatically；The relating module is used for root
Video camera is associated with monitoring head according to the zoom drive scope of camera lens so that the focal length of camera lens is being put
When big, monitoring head slows, and the focal length of camera lens is when reducing, the speed of monitoring head accelerates.
The automatic acquisition module includes detection switch and reading unit；The detection switch is used for the mirror for controlling video camera
Head carries out autozoom action；The reading unit is used for after the completion of autozoom action, and control panel reads camera lens
Zoom drive scope.
The relating module includes computing unit, connection unit and control unit, and the computing unit is used for acquisition
Zoom drive scope is implemented to be calculated as below：Zoom magnification=maximum focal length/minimum focus；The connection unit is used for zoom times
Number is precisely associated with monitoring head speed, and obtained connecting relation is that head speed is inversely proportional with zoom magnification；The control
Unit processed be used for according to connecting relation control monitoring head up and down and the speed that moves left and right.That is, working as connection unit
After zoom drive scope is precisely associated with monitoring head speed, during video camera normal work, reading unit can be at any time
The focal length of camera lens is read, and the focal length of reading is transferred to control unit, control unit can be according to the focal length of reading
Incidence relation according to zoom drive scope and monitoring head speed is controlled to the speed of monitoring head.
It is seen that, the present invention obtains the lens zoom scope of video camera by automatic identification technology, according to acquisition
Video camera is associated by the zooming range of camera lens with monitoring head, is reached above and below accurate control monitoring head and left and right
Translational speed, coordinate so as to realize and be attained by perfect action with any camera lens.The present invention enables to monitoring
The camera lens of head and any video camera is perfect compatible, without upgrading again and the supporting wiring board of stand-alone development, reduces cost.
