Abstract
The invention provides a multi-point touch interaction splicing method for realizing ultra-large size and ultra-high resolution display. The method comprises the following steps: (1) constructing a large-scale spliced touch screen; (2) fusing multi-projection images, wherein each splicing unit corresponds to a projector, and the images of a plurality of projectors are fused into a high-resolution large image through projection fusing software; (3) splicing a plurality of sensor images, wherein an infrared sensor is placed behind each splicing unit for capturing reflected light, the images of the sensors are spliced into an ultra-wide viewing field image by adopting image tracing software, and a large splicing screen is captured; (4) tracing contacts; (5) touching to response; (6) calibrating split screens. According to the method, the ultra-large size and ultrahigh resolution display is realized through screen splicing and multi-image fusion and splicing, so as to meet the requirements of people on the visible size and display resolution of a displayed image.
Description
Technical field
The present invention relates to a kind of touch display packing, the interactive joining method of especially a kind of multiple point touching.
Background technology
Multiple point touching refers to and allows the computer user to control simultaneously a kind of operator scheme of computing machine by a plurality of fingers or contact, and multiple point touching equipment is by tangible demonstration or shadow curtain equipment (as graphoscope, desktop, wall), also can be formed by touch pad, identify the point that the touch behavior occurs simultaneously and process by software afterwards.The screen that each multiple point touching technology based on optical principle comprises optical sensor (being generally camera or video camera), infrared light supply and shows by projector or display panel.
Along with the development of science and technology and the rapid expansion of quantity of information, but people are more and more higher to the requirement of the apparent size of display frame and display resolution.But at present, there is no a kind of method that realizes that well oversize and ultrahigh resolution show.
Summary of the invention
The invention provides a kind of interactive joining method of multiple point touching that can realize that oversize and ultrahigh resolution show.
Realize the interactive joining method of multiple point touching of the object of the invention, comprise the steps:
(1) build large-scale splicing touch-screen, at first utilize concatenation unit to splice in order a large-scale mosaic screen, then the surrounding at large-scale mosaic screen is covered with infrared light, forms total internal reflection in large-scale mosaic screen;
(2) many projected pictures merge, and the corresponding projector of each concatenation unit merges a plurality of projector pictures by the projection fusion software, is fused into a high-resolution large picture;
(3) multisensor picture splicing, infrared sensor of each concatenation unit back placement carries out catoptrical seizure, adopts picture charge pattern software that a plurality of sensor frames are spliced to form a super wide view field image, and large-scale mosaic screen is caught;
(4) follow the trail of the contact, and when finger being arranged by on large-scale mosaic screen, the total reflection of mosaic screen is destroyed, and the infrared light of pressing a little is returned, and picture charge pattern software can carry out the contact and follow the trail of;
(5) touch-responsive tracks contact and event according to picture charge pattern software, touches to drive to carry out touch-responsive;
(6) split screen calibration is carried out the split screen calibration to each concatenation unit, realizes that each point of touch-screen is corresponding one by one with the pixel of projector projects picture.
The beneficial effect of the interactive joining method of multiple point touching of the present invention is as follows:
The interactive joining method of multiple point touching of the present invention, by mosaic display screen, many pictures anastomosing and splicing is realized that oversize and ultrahigh resolution show, but has been satisfied people to the apparent size of display frame and the requirement of display resolution.

Fig. 1 is the splicing schematic diagram of the touch-screen of the interactive joining method of multiple point touching of the present invention.
Fig. 2 is the touch-screen fundamental diagram of the interactive joining method of multiple point touching of the present invention.
Embodiment
As shown in Figure 1, 2, the interactive joining method of multiple point touching of the present invention comprises the steps:
1) build large-scale mosaic screen
The mosaic screen that sequentially splices a large-scale formation total internal reflection according to splicing.
2) split screen adjustment and installation projector
Each corresponding projector in concatenation unit back, picture is covered with whole concatenation unit, every adjacent overlapping 10 above pixels of two concatenation unit pictures.
3) split screen adjustment and installation infrared sensor
Each corresponding sensor in concatenation unit back, the edge of the picture of sensor is the edge of concatenation unit, overlapping 10 the above pixels of two adjacent concatenation unit pictures.
4) projection fusion software is carried out many projections and is merged
By the projection fusion software, a plurality of projector pictures are merged, be fused into a high-resolution large picture.DirectShow module in the DirectX of projection fusion software employing Microsoft is carried out secondary development, adopts the method for Fusion Edges to carry out the picture fusion.
5) picture charge pattern software carries out many sensings picture splicing
Adopt picture charge pattern software that a plurality of sensor frames are spliced to form a super wide view field image, large-scale mosaic screen is caught.Picture charge pattern software carries out a series of normal image that superposition boundary arranged or video image seamless spliced, thereby obtains the image of super wide visual field.
6) follow the trail of the contact
When finger being arranged by on large-scale mosaic screen, the total reflection of mosaic screen is destroyed, and the infrared light of pressing a little is returned, and picture charge pattern software can carry out the contact to be followed the trail of, and the tracking result sends to the master hosts system with TUIO.
7) touch driving
The master hosts system tracks contact and event according to picture charge pattern software, and operating system is carried out touch-responsive, the touch operation that application response is corresponding.
8) split screen calibration
Each concatenation unit is carried out the split screen calibration, realize that each point of touch-screen is corresponding one by one with the pixel of projector projects picture.
Embodiment recited above is described the preferred embodiment of the present invention; be not that scope of the present invention is limited; design under spiritual prerequisite not breaking away from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical solution of the present invention all should fall in the definite protection domain of claims of the present invention.
