Technical field
The present invention relates to a kind of multiconductor image recognition interaction systems, belong to the electronic display unit technical field.
Background technology
Existing multiconductor image recognition interaction systems generally adopts rectilinear touch screen as the main flow input technology, needs the unsettled arm type operation of user.But the user lifts hand in front a period of time when controlling after, arm can produce ache, the sensation such as narrow, edema.
Summary of the invention
The problem that do not meet ergonomics of the present invention for existing in the existing multipoint-touch-technology of solution, and then a kind of multiconductor image recognition interaction systems is provided.For this reason, the invention provides following technical scheme:
Multiconductor image recognition interaction systems comprises:
Touch-screen at least one infrared light supply of planar arranging;
Be used for taking at least one infrared induction camera of the luminous infrared contact of described infrared light supply;
The infrared contact that described infrared induction camera is taken is by coordinate setting and the picture signal of location is sent to the image-signal processor of display device;
Display device with described picture signal demonstration.
The technical scheme that embodiment of the present invention provides is by the infrared contact of infrared induction camera shooting infrared light supply on touch-screen, and mated demonstration by coordinate setting by image-signal processor on screen, realize that the user directly operates on touch-screen, meet principle of human engineering, can be suitable for the screen of various special-shaped off-standard sizes, have registration, mate the characteristics such as the interactive coordinate of screen touch, system stability, debugging is convenient, maintenance cost is low fully.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The specific embodiment of the present invention provides a kind of multiconductor image recognition interaction systems, as shown in Figure 1, comprising:
Touch-screen at least one infrared light supply 1 of planar arranging;
Be used for taking at least one infrared induction camera 2 of the luminous infrared contact of described infrared light supply;
The infrared contact that described infrared induction camera is taken is by coordinate setting and the picture signal of location is sent to the image-signal processor 3 of display device;
The principle of this embodiment (for example: the equipment that multiple point touching technology camera) is built is based on optics, (English is called for short the infrared light supply 1 that wherein adopts: be IR) part on spectrum, the visible light that just crosses the border and to see in mankind's eyes, its scope is longer than visible light but is shorter than microwave, " near infrared " (the English abbreviation: NIR) be in the lowest part on infrared spectrum, general approved wavelength is that 700nm (nanometer) is between 1000nm.The sensor of most of digital camera heads is to infrared very sensitive, installs one additional before need to the eyeglass at camera in based on the multiple point touching technology of optics can leach the eyeglass that other wavelength light receive only the corresponding infrared ray glistening light of waves.In the multiple point touching technology, the infrared light supply Main Function is in visual interface and object or the finger vestige of difference touch-surface.In view of a lot of systems all with projection or display as the equipment that shows, therefore can allow infrared induction camera 2 only read object or finger feedack point.
Concrete, can adopt infrarede emitting diode as infrared light supply 1 in this embodiment; Display device 4 can adopt display, perhaps the combination of projector and rear-projection display screen.Image-signal processor 3 can adopt the graphics workstation of INTEL series, has completed infrared contact that infrared induction camera 2 is taken by coordinate setting, realizes coupling demonstration on screen.
The principle of work of this embodiment is: as shown in Figures 2 and 3, on the giant-screen surface, adopt a plurality of Infrared laser emission devices, screen surface is covered one deck infrared light, two infrared cameras are placed in the screen back side, and corresponding camera lens is set, reflective infrared luminous point in whole screen is filmed, the signal of taking is transferred to the graphics process workstation, by the analysis of graphics process workstation to shooting picture, with the infrared contact that photographs, by coordinate setting, on coupling and screen, complete the correct screen coordinate data of cover.Pass through at last the protocol interface output display of standard to display device 4.Protocol interface wherein can adopt Socket TCP/IP interface, can corresponding Windows series, the multimedia application software such as Flash, Flex, Director
Multiconductor image recognition interaction systems provided by the invention is by the infrared contact of infrared induction camera shooting infrared light supply on touch-screen, and mated demonstration by coordinate setting by image-signal processor on screen, realize that the user directly operates on touch-screen, meet principle of human engineering, can be suitable for the screen of various special-shaped off-standard sizes, have registration, mate the characteristics such as the interactive coordinate of screen touch, system stability, debugging is convenient, maintenance cost is low fully.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the embodiment of the present invention discloses; the variation that can expect easily or replacement are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
