Abstract

The invention relates to an indoor wireless audio and video holographic interactive rear projection integrated machine which has a simple structure and is convenient to use and an implementation method. The integrated machine comprises at least one service-end integrated machine and a front-end accessory, wherein the service-end integrated machine comprises a control circuit and a projection circuit, which are mounted in a housing; the control circuit is provided with a video input and output interface and a wireless audio sending module; an infrared optical filter is arranged in front of a camera head of the projection circuit; and the front-end accessory comprises a base body which is positioned at the upper part or the lower part or the side part of a projection screen and in the size corresponding to the side length of the projection screen, at least two infrared light sources are arranged at two ends of the base body, and at least two infrared light sources respectively perform projection in 45-degree tilting directions, thereby forming an infrared plane which infinitely approaches the projection screen and being parallel the projection screen plane.

Description

technical field [0001] The invention relates to an indoor wireless audio and video holographic interactive rear projection all-in-one machine and a realization method. Background technique [0002] In the existing infrared touch projection technology, the construction of the system requires various product combination schemes to be matched and installed. The method is complex and requires professional and technical personnel to install and debug. The transportation is inconvenient and the cost is high, which is not conducive to the development of product industrialization. The algorithm in the prior art is complex and the amount of calculation is large, all calculations are completed by the central processing unit, and the energy consumption of the machine is relatively large. The existing technology cannot simultaneously solve the problems of splicing of projection images, splicing of collection and processing, and accurate alignment. The existing technology cannot guarant...
