Problems solved by technology

[0003] The application of interactive projection technology in China is relatively mature, but all projection equipment is only suitable for display and interaction in public places. There is no suitable product in China to provide more convenient and efficient services for the public. Traditional products can no longer meet the needs of projection users, let alone truly Realize the convenience, popularization, commercialization and intelligence of projection interactive products

Embodiment Construction

[0026] like Figure 1-5 As shown, the implementation method of an interactive light-sensing touch micro-projection system described in the embodiment of the present invention includes four technical levels of infrared emission capture system, hand position recognition, hand motion recognition and interactive design software system development, four Data at the technical level is transmitted and processed sequentially, including the following steps:

[0027] 1) Infrared emission and capture system: The infrared rays emitted by the infrared emitter will be reflected after touching the hand, and the reflected light will enter the infrared receiver in the system, and the infrared receiver will project the reflected light to obtain the infrared distribution;

[0028] 2) Extraction of hand information: use the background subtraction method to extract, pre-process to obtain the threshold value of each area of ​​the image, the grayscale of the image captured by the infrared camera pre...

Abstract

The invention relates to a realizing method of an interactive light sensitive touch miniature projection system, which comprises four technical levels of an infrared emission catching system, identification of a hand position, identification of a hand action, and development of an interactive design software system; data of the four technical levels are transferred and processed sequentially. The method concretely comprises the following steps of: 1) reflecting infrared rays emitted by an infrared emitter through the infrared emission catching system after the infrared rays meet a hand; enabling the reflecting light to enter an infrared receiver; projecting the reflecting light by the infrared receiver for obtaining an infrared distributing condition; 2) extracting the information of the hand; and 3) realizing a multi-point touch control system. The realizing method has the advantages that the interaction is dynamic; the information can be transferred; interaction display in a public place is converted into individual private interaction; a product does not occupy or use space and can be fixed and carried; the application range is wide; and the product has great market potential in various service industries.

Description

technical field [0001] The invention relates to the application field of projection systems, in particular to a method for realizing an interactive light-sensitive touch miniature projection system. Background technique [0002] Interactive projection media based on light-sensitive touch technology, referred to as interactive micro-projection, is a portable projection media system that introduces functions such as dynamic capture, image recognition, multi-touch, and interactive network, integrating interactivity, convenience, and practicability. , marketability in one, suitable for indoor places such as offices, restaurants, and homes. The interactive interface is projected onto the wall or desktop through a miniature projector, and people only need to select it with their fingers to generate interaction (such as conference projection explanations, restaurant projection tabletops, projection interactive games) [0003] The application of interactive projection technology in...
