Embodiment

Below in conjunction with Figure of description the present invention is done further description.

As shown in Figure 1, the said a kind of method for controlling projection of the embodiment of the invention, this control method is to utilize light beam and recognition device to carry out in the projected image area perimeter alternately, accesses Control-Menu and tabulates and projection arrangement is controlled in the projected image area.

This control method may further comprise the steps:

Obtain the light beam information and/or the beam-pointing positional information that are in the outer imaging identification zone of projected image area;

Recognition result is discerned and exported to the above-mentioned light beam information that gets access to, and/or the above-mentioned beam-pointing positional information that gets access to is carried out analyzing and processing draw analysis processing result;

Export the respective projection data message according to described recognition result and/or analysis processing result, and this data for projection information is shown in said projected image area.

In the said method principle, mention light beam information in the imaging identification zone and/or beam-pointing positional information outside the projected image area.For this light beam information and beam-pointing positional information, can make following explanation:

Light beam information is that the light beam that sends of beam launcher optional position in the imaging identification zone outside projected image area is carried out and clicked, double-click, somely hits or pin motionless order time institute identified information, and these light beam information interior data for projection information of corresponding pre-set programs respectively; The beam-pointing positional information is the upper and lower, left and right position time institute identified information of light beam in the identified region scope and outside projected image area that beam launcher sends, and these beam-pointing positional informations are also respectively for the data for projection information in the pre-set programs.On the basis of two kinds of information, can light beam position and stroke commands be combined, represent a kind of information jointly, the data for projection information in the corresponding program.

For light beam information how to discern various dependence order controls.The first, said light beam is the time of staying in the imaging identification zone outside said projected image area.This kind method can determine to click and pin the light beam information when motionless; The second, said light beam occurrence number in the imaging identification zone outside said projected image area in the set time, this kind method can determine to double-click or the light beam information during some hitting.

Light beam information processing process is:

The first, judge that the said light beam time of staying get access to whether less than Preset Time, is to export the first recognition result information (object information when just clicking); Otherwise, export second recognition result information when motionless (just pin object information);

The second, discern the number of times of the said light beam appearance that gets access to, export corresponding recognition result information according to this number of times.

The processing procedure of beam-pointing positional information is:

Image processing program according to preset carries out graphical analysis to the said beam-pointing positional information that gets access to, and determines zone of living in, said beam-pointing position and output.

As further embodiment of the present invention, make simple control procedure to concrete device according to the said principle of this control method:

1) projection arrangement projects images zone, the image-region of wherein said projection arrangement is less than the identified region of said recognition device;

2) beam launcher is clicked, double-clicked or pins motionless, it transmits a light beam to upper and lower a, left side or the right side of image-region;

3) upper and lower, the left side of recognition device (can be camera) identification image-region that light beam arrive or right side, the collection identifying information carries out analyzing and processing, and the object information after the processing is transported to projection arrangement;

4) projection arrangement projects the Control-Menu tabulation according to the object information output data for projection information after handling at image-region;

5) beam launcher is controlled and sent light beam to the Control-Menu tabulation, accomplish corresponding operating.

In step 3), will carry out the analyzing and processing process of recognition device to identifying information, in this process, need identification module image acquisition module and image processing module in the recognition device to accomplish jointly, this process is:

1, identification module image acquisition module is gathered the luminous information of restrainting the perimeter of the image-region that arrives of beam launcher institute, and Information Monitoring is exported;

2, image processing module obtains processing result information after receiving the Information Monitoring of output and carrying out analyzing and processing and is transported to projection arrangement.

In step 4), will carry out the control procedure of projection arrangement after to signal processing, in this process, need projection application module and projection module in the projection arrangement to accomplish jointly, this process is:

I, projection application module are sent data for projection information behind the object information after the reception image processing module is handled;

Ii, projection module receive data for projection information and on image-region, project the Control-Menu tabulation.

The Beam Control that this method for controlling projection carries out outside projected image area; Comprise three kinds of orders that trigger light beam; Be respectively to beam launcher carry out click, double-click and pin motionless, make occur outside image-region that luminous point once glimmers, twice flicker or flicker slightly for a long time.And these variations of recognition device identification; And carry out message transmission with projection arrangement; Make predetermined system in the projection arrangement call according to variation that different light beams trigger pairing data for projection information (screen menu type adjusting information) on the diverse location; On image-region, show the Control-Menu tabulation, accomplish control operation.Such as, light beam once glimmers at the image-region upside, and being presented at last in the image-region is the data for projection information of system's defined to changing, and on image-region, shows the Control-Menu tabulation, accomplishes control operation.

As shown in Figure 2; Because the angle of recognition device identification is bigger than the image-region of projection; So control method of the present invention can be applied to outside the image-region of projection according to different system definition, reach the function expansion purpose of removing the projected image area inner control.
