Embodiment Construction

[0008] According to Fig. 1, the signal processor (curing the required corresponding program of the present invention) is respectively connected with IP set-top box, camera (CMOS or CCD imaging device), projection system, wireless receiver (it can be 802.11, bluetooth; also can select for use Such as 315MHz, 433MHz or other wireless transceivers) to realize electrical connection; IP set-top box and network are realized effective interconnection; The laser emitter (laser diode), the power supply, and the wireless emitter (the emitter matched with the wireless receiver) are electrically connected; under the coordination of related programs, the present invention can be realized. Realize the physical composition of the present invention as shown in Figure 2.

[0009] Working principle: To realize the IP interaction of projection on the display screen, first press the light button on the remote control, and the laser light will be lit. And let the laser spot point to the position ...

Abstract

A method for realizing interactive projection system including confirmation signal by remote controller to confirm transient time to shoot laser spot position image by video camera tube, comparing screen image set with laser spot and slot by video camera tube with original image sent to be projected at this moment by signal processor for calculating and seeking out position coordinate of laser spot in original image and for activating IP address corresponding linked to said position coordinate so as to realize interdynamic.

Description

technical field [0001] The invention relates to a method for realizing a projection system. More specifically, it relates to an implementation method of an interactive projection system. Background technique [0002] As we all know: because the display screen of the projection system has no perception function, none of the existing projection systems can touch the screen for interaction. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a simple and easy-to-implement realization method of an interactive projection system. [0004] The present invention adopts the following technical scheme: it is composed of a network, an IP set-top box, a projector, a display screen, a remote controller, and related programs. connection; the IP set-top box is effectively connected to the network; the microprocessor in the remote control is electrically connected to the laser transmitter, button, power supply, and wi...
