In a word, although above-mentioned existing electronic interactive blank has their own characteristics each, they all need a substrate as sensing media, have that inconvenience is carried and use, the high defective of cost of manufacture.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned prior art defective, a kind of low-cost self-adaptation type intelligent interaction projector that need not that physical sensing medium, screen size can be demarcated arbitrarily, positioning resolution is high is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of self-adaptation type intelligent interaction projector, comprise computing machine in the formation, digital projector, infrared image sensor and infrared exoelectron pen, the picture signal of described computing machine output is sent into the video input interface of digital projector through the VGA video line, the infrared signal that described infrared exoelectron pen sends is incident upon on the projection plane of digital projector, the position of the corresponding projection plane epigraph of the infrared signal that infrared signal reflects on projection plane, the infrared signal of reflection is sent into infrared image sensor, described infrared image sensor is built-in with bluetooth module (U3), and the blue teeth wireless signal of its output is sent into computing machine.
Above-mentioned self-adaptation type intelligent interaction projector, described infrared image sensor is made of CCD camera, single-chip microcomputer and bluetooth module, the output signal of described CCD camera connects the PORT1 interface of single-chip microcomputer, and the TXD of described bluetooth module, CTS, RXD, RTS end connect RXD/P3.0, INTO#/P3.2, TXD/P3.1 and the P1.7 end of single-chip microcomputer respectively by level translator.
Above-mentioned self-adaptation type intelligent interaction projector, described infrared exoelectron pen by the infraluminescence pipe that is loaded on nib, be loaded on the pen on one's body pushbutton switch and the current-limiting resistance and the battery of a body inside form, described infraluminescence pipe connects battery through current-limiting resistance and pushbutton switch.
Above-mentioned self-adaptation type intelligent interaction projector, the infrared signal input end of described infrared image sensor is provided with infrared filter.
The utility model utilizes infrared image sensor to catch an infrared exoelectron displacement signal, and this signal is sent to computing machine in the Bluetooth wireless transmission mode, computing machine adopts the realtime graphic treatment technology, analog digital ink and mouse control in the figure that computing machine shows realize writing and the interactive operation that shows.Because this device need not the physical sensing medium and makes substrate, thereby low cost of manufacture and being easy to carry.Simultaneously, by 4 demarcation self-adaptation screen sizes, this device can obtain high orientation precision and can work in the screen of arbitrary dimension.
