Intelligent interactive projection system

Abstract

The present invention discloses an intelligent interactive projection system. The system comprises a projection screen, an intelligent projector, a camera, an infrared emitter and an intelligent terminal. The intelligent projector comprises a miniature projector and a service controller; the miniature projector and the camera are adjusted in angle, so that the view angle covers the projection screen; the infrared emitter is arranged at the front upper part of the projection screen and forms an infrared light surface parallel to the projection screen in front of the projection screen; the intelligent terminal is wirelessly connected to the service controller and pushes projection content or a control instruction to the service controller; when a finger touches the projection screen, the finger passes through the infrared light surface, and then the camera captures an image formed by reflecting infrared light and sends the image to the service controller for gesture recognition; and the service controller feeds back an operation instruction to control the play of a projection, thereby achieving the intelligent interaction. The system provided by the present invention has the advantages of being low in cost, high in performance, convenient and user-friendly, and has good user experience.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to an intelligent interactive projection system. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] With the continuous update and development of projector technology and its wide application in daily life, people have more and more requirements for the convenience and interactivity of projection control. However, most products can only be controlled by infrared pen or electromagnetic pen at present. It is impossible to realize multi-touch control by hand, and there are disadvantage...

[0003] With the continuous update and development of projector technology and its wide application in daily life, people have more and more requirements for the convenience and interactivity of projection control. However, most products can only be controlled by infrared pen or electromagnetic pen at present. It is impossible to realize multi-touch control by hand, and there are disadvantages such as high cost, inaccurate positioning, slow response speed, and limited projection surface material, which cannot bring a better experience to users
