When the infrared rays pass through the transparent screen of the projection screen and the table body, they will bounce back into the table body; ' is disposed in the table body' and is directed toward the projection screen of the table body at an oblique angle, and reflects the infrared light that bounces back into the table body; at least one infrared camera is disposed in the table body and faces the lens In addition, the at least one infrared camera is electrically connected to the computer machine' and captures the infrared light reflected by the mirror, and the computer host analyzes the face image captured by the at least one infrared camera to calculate the display of the computer output. Where is the face touched. @ The above technical means uses the projection method to present the image on the desktop, using the infrared light emitted from the table to the desktop and the position of the electricity: rebounding the infrared light, thereby judging that the desktop is touched by the surface: the brain host can be more touched The control panel recognizes multi-touch more accurately. The table of this creation does not require a large-area touch panel, so it can cost 4 M355612. [Embodiment] A preferred embodiment of the present invention, as shown in the first figure, includes a table (10), a computer host (20), a short-range projector (30), and a plurality of infrared projectors. (40), a mirror (50), at least one infrared camera (60), a set of eight (70) and a heat dissipation module (80). The table body (10) is hollow, and the table body (10) has a transparent table top (11) and a projection screen (12), and the projection screen (12) is correspondingly disposed on the transparent table top (11). In addition, the table body (1 〇) is further provided with a light scattering unit (13) on the inner side wall except the table top (11), and the surface of the light scattering unit (13) is formed with irregular concave lines. (131), detailed about its role. The computer host (20) is disposed in the table body (1), and the computer host (20) is equipped with a software that can filter images and define coordinates in the image. In this embodiment, the touchLib software is used. Regarding how the computer host (20) filters the image and defines the coordinates in the image, it will be detailed later. Please refer to the second picture shown above. 'The short-range projector (3〇) is installed in the table body (10), and faces the projection screen (12). The short-range projector (3〇) is also connected. The computer host (20) is electrically connected, and the display screen outputted by the host computer (2〇) is projected on the projection screen (1 2); since the projection distance required by the general projector is shorter than the projector (3)投影) The projection distance is about twice as long (generally, if the projector wants to achieve a horizontal projection width of 彳_2 meters, the projector must be placed about 2.4 meters away from the projection screen), and the creation is a table. Therefore, in order to avoid too long projection distance, the height of the table is too high, so the 5 M355612 is created with a short-range projector (30), so that the height of the table can be maintained at an appropriate south. The plurality of infrared light projectors (40) are disposed in the table body and emit infrared rays toward the entire projection screen (10). Please refer to the second figure as shown when the infrared rays pass through the projection screen (12). After the transparent desktop (11), if an obstacle is encountered, for example, the user touches the transparent desktop (彳彳) with the finger, the infrared light will rebound into the table body (彳〇). In addition, in order to make the infrared light can be uniformly and comprehensively projected toward the projection screen (12), and can avoid the hot spot (Sp〇t) generated by the general infrared ray illuminator after emitting infrared rays, and affecting the subsequent identification of the touch position, a specific The method adopts a matrix type infrared light projector having 140 infrared light bulbs therein, and the matrix type infrared light projector is facing the inner side wall of the non-desktop (11), and is matched with the inner side wall of the table body (10). The upper reflective scattering unit (13), when the infrared ray is irradiated onto the reflective scattering unit (13), the infrared ray will be reflected by the reflective scattering unit (13), since the surface of the reflective scattering unit (13) has a concave pattern (131) The bumps are uneven, so that the infrared rays are evenly scattered toward the table top (11), so that the infrared rays can be prevented from being too concentrated in the production area somewhere on the projection screen (12), so as to reduce the influence of subsequent touch recognition. Please refer to the second figure +, w, +, c, and the mirror (50) is not installed in the table body (10), and is turned at a tilt angle. Projection screen of the table (1 〇). 2), in order to reflect the infrared rays that bounce back into the table body (1〇); in the embodiment, the mirror (5G) is disposed on the inner side of the bottom surface of the table body (1Q). Please refer to the second figure for the thousand μ, and the mouth is not, and at least one infrared camera (60) is provided. If it is more clearly photographed, it can be said to be abbreviated | a ,. 〇), in this embodiment, a two-inch έτ recognition A w ,,, σ infrared camera (60) is disposed in the body (10) of the table M355612 and is disposed toward the mirror (5〇), The infrared camera (6〇) is electrically connected to the host computer (2〇)' and captures infrared rays in the image reflected by the mirror (5〇); however, in view of the price of the infrared camera on the market, The infrared camera (6〇) can also be used for general cameras. Ren must install a visible light filter on the camera lens to filter visible light' so that the camera only receives infrared light. Because of the general camera's shooting area and the camera and the shooting surface. The distance is longer, the wider the area that can be photographed, the purpose of the mirror (50) is to divide the necessary photographic distance between the projection screen (12) and the infrared camera (6 〇). Paragraph The distance between the projection screen (12) to the mirror (5〇) and the mirror (50) to the camera (60), so that the height of the table can be maintained at an appropriate height. Therefore, for this implementation In the example, a mirror (50) is disposed on the inner side of the bottom surface of the table body (10), and the infrared camera (60) is disposed on the inner side of the table top (11). When the computer host (20) obtains the infrared camera (6〇) After the image of the shirt is captured, the infrared light from the touched area will be reflected. Therefore, in the image captured by the infrared camera (60), a light spot is formed at the touched position (as shown in Annex 1). The TouchLib software can be processed by techniques such as noise removal, contrast enhancement, dilation and etching (erosl_〇n) by using the information such as the intensity of the spot and the degree of blur obtained on the image of the shirt. Filter out the touch area (as shown in Appendix 2), and then calculate the coordinates of the touch, and the host computer (20) judges where the touched part is on the display surface of the output, and then the computer host (20) Then corresponding to the user's touch change The output display screen is projected by the short-range projector (30) onto the projection screen (1 2), so as to achieve the effect of interacting with the user M355612 'for example, the user can touch Display the objects on the screen for dragging, opening, closing, etc. (as shown in the third figure).
