Definitions

  • the invention relates to the field of projection display technology and human-computer interaction, and in particular to an infrared projection system.
  • DMD light modulators Most of the current miniature projection optomes use DLP technology from Texas Instruments, and their main image and light control devices are generally referred to as DMD light modulators. It is a micro-mirror array with extremely high reflectivity. It needs to be combined with the illumination optics and projection optics to convert the commonly used RGB three primary colors into a projection image that is easy for us to see.
  • a commonly used method of combining an illumination optical system and a projection optical system is to use a total internal reflection element having a lens surface.
  • the common human-computer interaction implementation scheme is to use an ordinary incandescent light source projector to project an image, an infrared light source to illuminate the screen, and an infrared camera to capture the screen infrared image, thereby capturing the user's finger movement on the screen.

Abstract

La présente invention se rapporte à un système de projection infrarouge qui comprend : un module de projection permettant de générer des images interactives et une lumière infrarouge; un module appareil photo (600) servant à acquérir chronologiquement les images interactives et la lumière infrarouge projetées par le module de projection; et une zone de projection (700) permettant de projeter les images interactives et la lumière infrarouge. Le module de projection comporte : une unité source de lumière à LED (300); une unité source de lumière infrarouge (200); une unité de combinaison de lumières (100) permettant de combiner la lumière émise par l'unité source de lumière à LED (300) et l'unité source de lumière infrarouge (200); une unité d'affichage d'images (400) servant à générer des images de projection; et une lentille (500) permettant de recevoir les images en provenance de l'unité d'affichage d'images (400) et réfléchies par l'unité de combinaison de lumières (100). Ladite unité de combinaison de lumières (100) comprend un groupe de prismes et un groupe de lentilles servant à transmettre et réfléchir la lumière émise par cette unité source de lumière à LED (300) et cette unité source de lumière infrarouge (200), puis à permettre l'incidence de la lumière dans l'unité d'affichage d'images (400) pour la convergence. Grâce à la combinaison de la lumière de la source de lumière à LED et de la source de lumière infrarouge, la présente invention réalise des opérations interactives homme-machine, sans utiliser de dispositif infrarouge externe.
