Embodiment
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Figure 1, a kind of method for controlling projection described in the embodiment of the present invention, this control method is to utilize light beam and recognition device to carry out in projected image area perimeter alternately, recalls Control-Menu list and in projected image area, projection arrangement is controlled.
This control method comprises the following steps:
Obtain the light beam information in imaging identification region and beam-pointing positional information outside projected image area;
Recognition result is identified and exported to the above-mentioned light beam information getting, and the above-mentioned beam-pointing positional information getting is carried out to analyzing and processing draw analysis processing result;
Export corresponding data for projection information according to described recognition result and analysis processing result, and this data for projection information is shown in described projected image area.
In said method principle, mention the light beam information in imaging identification region and beam-pointing positional information outside projected image area.For this light beam information and beam-pointing positional information, can make following explanation:
The light beam that light beam information is sent for beam launcher optional position in imaging identification region outside projected image area is carried out and is clicked, double-click, some information of identifying while hitting or pin motionless order, and these light beam information data for projection information in corresponding pre-set programs respectively; The information of identifying when the position, upper and lower, left and right of the light beam that beam-pointing positional information is sent for beam launcher within the scope of identified region and outside projected image area the, and these beam-pointing positional informations are also respectively for the data for projection information in pre-set programs.On the basis of two kinds of information, light beam position and stroke commands can be combined, jointly represent a kind of information, the data for projection information in corresponding program.
For light beam information how to identify various dependence order controls.The first, described light beam is the time of staying in imaging identification region outside described projected image area.This kind of method can determine to click and pin the light beam information when motionless; The second, described light beam occurrence number in imaging identification region outside described projected image area within the set time, this kind of method can determine to double-click or light beam information when some hitting.
The processing procedure of light beam information is:
Whether the described light beam time of staying that the first, judgement gets is less than Preset Time, is output the first recognition result information (object information while namely clicking); Otherwise, output the second recognition result information when motionless (namely pin object information);
The second, the number of times that the described light beam that identification gets occurs, exports corresponding recognition result information according to this number of times.
The processing procedure of beam-pointing positional information is:
According to default image processing program, the described beam-pointing positional information getting is carried out to graphical analysis, determine region of living in, described beam-pointing position output.
As further embodiment of the present invention, make simple control procedure according to principle described in this control method for concrete device:
1) projection arrangement projects images region, the image-region of wherein said projection arrangement is less than the identified region of described recognition device;
2) beam launcher is clicked, double-clicked or pins motionless, it transmits a light beam to upper and lower, the left or right side of image-region;
