When finger is in the time touching the screen of infrared multi-point touch screen, will block two infrared rays anyhow through this position, thereby can judge the coordinate position of touch point at screen.Any nontransparent object all can change the infrared ray on contact and realize touch screen operation.Infrared multi-point touch screen is to touch product with respect to the one of single-point infrared screen and virtual 2 infrared screen, be a kind of technical renovation of infrared touch panel, its principle mainly solves by the algorithm of software in firmware the not interference problem that more than simultaneously touches operation at 2.True 2 and virtual 2 s' difference shows high stability and response is upper fast, can hop, run the maloperations such as point.
Infrared multi-point touch screen major defect has at present:
(1) surround lighting factor, infrared receiving tube has the working range between minimum sensitivity and maximum illuminance, but touch-screen product but can not limit usable range.
(2) signal diffraction, peripheral reflection, refraction, interference, infrared transmitting tube has an emission angle, receiving tube has acceptance angle in a big way, if peripheral reflection to a certain extent, finger is placed on and where also stops incessantly signal, can accomplish accurate touch to the suitable adjustment of its power.
(3) response distance, when finger leaves after frame, the operation that just cannot continue;
(4) although can realize multiple point touching, can not realize gesture identification simultaneously.
Summary of the invention
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of multiple point touching and gesture identification emerging system.
In order to realize above-mentioned target, the utility model adopts following technical scheme:

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Shown in seeing figures.1.and.2, the utility model multiple point touching and gesture identification emerging system, comprise: projector 1, projection blank 2, generating laser 3, camera module 4, data processing equipment 5, projector 1 is for projection image on projection blank 2, on projection blank 2, be provided with the generating laser 3 for Emission Lasers, the laser of finger reflection when camera module 4 operates on projection blank 2 for receiving finger, data processing equipment 5 connects respectively projector 1 and camera module 4, data processing equipment 5 is realized multiple point touching and gesture identification for the signal obtaining by camera module 4.
When actual motion, data processing equipment 5 connects projector 1, the various information exchanges of data processing equipment 5 are crossed to projector 1 after projection blank 2 upslide frame outs, projector 1 is connected to upper data processing equipment 5, open respectively generating laser 3 and camera module 4 simultaneously, carry out just can realizing finger touch replacement mouse action after the calibration of simple location through the software on data processing equipment 5.In the time that finger operates on projection blank 2, the laser that receives finger reflection by camera module 4 is determined position, thereby realizes multiple point touching.In the time that finger leaves projection blank 2, by the imaging of taking pictures of camera module 4, data processing equipment 5 calculates, thereby realizes gesture identification.The utility model has solved the problem that in prior art, multiple point touching and gesture identification can not be compatible thus, can realize the fusion of multiple point touching and gesture identification, make the utility model more intelligent turning in use, make user's experience more perfect.In addition, add camera module 4 due on the utility model is in system, can filter surround lighting factor by camera module 4, therefore can avoid the working range of existing infrared multi-point touch screen to be difficult to the shortcoming of restriction.In reality, as preferably, between generating laser 3 and camera module 4, realize signal transmission by the wave band of 850nm.The signal that so just can make camera module 4 tear can be accurate.In addition, carry out Emission Lasers because the utility model has adopted generating laser 3, therefore can as traditional infrared multi-point touch screen, not exist signal diffraction excessive, can not realize the ability of accurate touch.Further, because traditional infrared ray has certain response distance, and the utility model has adopted laser, and therefore the utility model is no longer confined to only on the less touch-screen of area, use, can realize large-screen interactive, the size of projection blank 2 does not limit.
The utility model is the particular type of restricting data treatment facility 5 not, also the type of attachment between restricting data treatment facility 5 and projector 1 and camera module 4 not, as preferably, data processing equipment 5 is individual PC, thereby makes application of the present utility model very extensive.And in reality, can will between data processing equipment 5 and projector 1, connect by VGA cable 6, between data processing equipment 5 and camera module 4, connect by USB cable 7.In addition, can, at data processing equipment 5, such as individual PC is upper, relevant data processing, the software of image gesture identification be installed, coordinate data processing equipment 5 itself to realize better the utility model, make the utility model according to intellectuality.The utility model does not limit the design of various softwares, and those skilled in the art are designed according to reality.
Multiple point touching of the present utility model and gesture identification emerging system can be realized the fusion of multiple point touching and gesture identification, the utility model touches precisely, can realize large-screen interactive, the relative prior art of the utility model more intelligent turning in use, user's experience is more perfect.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
