It double-clicks in target location, and controls photoelectronic tracking device 3 into state is automatically tracked, if location information is consistent, then it is assumed that be
The maloperation of operator, without automatically tracking.
Below by one group of embodiment, the present invention will be further described:
This programme is used as controlling equipment using the control computer 1 with touch screen, passes through operator's point touching screen
Mode by goal directed to field of view center, can simplify target following confirmation automatically.This programme is specific as follows:
The first step selects the display with touch screen as the display operation terminal for controlling computer 1, and by photoelectric tracking
The view field image of device 3 is shown over the display；
It the use of the display for having touch function is the basis that can receive operator and click control function.Common electricity
Resistive or capacitive touch screen can work well.
Second step operator clicks in the position that target occurs；
Operator observes display, confirms target position.Target position is clicked using finger tip, controls 1 basis of computer
Visual field size calculates target and field of view center orientation and pitch angle.After operator double-clicks, man-machine interaction unit software can be with
It is obtained by Message Processing and double-clicks position.Visual field described in this example is one piece of rectangular display area, and horizontal direction indicates light
Electric tracing tool face azimuth, vertical direction indicate photoelectronic tracking device pitching.Due to visual field azimuth and pitch angle be it is fixed, because
This, can calculate variance deviation and pitch deviation value by following formula, it may be assumed that

Pitch deviation value=(target vertical deviation pixel value/visual field Vertical number of pixels) * photoelectronic tracking device pitching size；
Third step is controlled computer 1 and is rotated using the turntable 4 of deviation control photoelectronic tracking device 3, will be drawn with confirmation target 7
Lead field of view center.Operator double-clicks the location of target on touch screen, after control computer 1 judges target position information
Determine whether that control photoelectronic tracking device 3 enters and automatically tracks state；
Control computer 1 finds out and is sent to photoelectronic tracking device 3, control photoelectronic tracking device for it as input after deviation
3 turntable 4 rotates, by goal directed to field of view center.Guidance accuracy in this case turns precision about equal to turntable
10mrad corresponds to about 1/20 visual field on display.It requires to enter 1/3 region of field of view center much smaller than the operation of photoelectronic tracking device 3
Place carries out the requirement of tracking confirmation.
Operator double-clicks on touch screen behind target location, control computer 1 by this location information and photoelectricity with
The target position that track device 3 is sent is compared, if consistent it is determined that operator's double-click is controlled in target location
Photoelectronic tracking device 3 processed, which enters, automatically tracks state, otherwise it is assumed that being the maloperation of operator, is not processed.Use position
Judgement can effectively reject maloperation, improve the reliability of tracking.
In conclusion technical solution of the present invention makes the operation of operator's trick at one, and it is easy to operate, to operator
The qualification of member does not require substantially；The precision of goal directed to field of view center is high, it can effectively improve tracking confirmation
Reliability.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention may be used also on the basis of the above description for those of ordinary skill in the art
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is all to belong to this hair
The obvious changes or variations that bright technical solution is extended out are still in the scope of protection of the present invention.
