Abstract

The invention provides a virtual reality interaction system based on 3D interaction. The virtual reality interaction system comprises a data helmet, a light tracking camera set, a multi-point touch screen, a back projector display screen, a back projector, a front side projector, a main control unit, a microcomputer set and an HDMI cable, the light tracking camera set is placed at the upper portion of a room, and the distance between adjacent cameras is the same; the back projector display screen is placed at the portion, at the upper portion of the multi-point touch screen, perpendicular to the ground, the multi-point touch screen is horizontally placed, the two screens have the same size, and the long sides of the two screens are connected and are perpendicular to each other; the data helmet is worn by the head of an observer and right faces the back projector display screen; the back projector is placed at the portion an appropriate distance away from the back projector display screen, and the front side projector is placed at the portion an appropriate distance away from the multi-point touch screen; the microcomputer set is connected with the back projector display screen andthe multi-point touch screen through the HDMI cable respectively, and the main control unit is in wireless connection with the light tracking camera set. The virtual reality interaction system is simple in circuit connection, and an obtained image is high in resolution and interactivity.

Description

technical field [0001] The invention relates to a virtual reality system based on 3D interaction, which belongs to the fields of stereoscopic display technology and virtual reality technology. Background technique [0002] The stereoscopic display system not only provides flat images, but also brings 3D images with depth information to the audience, which can deepen the audience's sense of presence. Currently, the stereoscopic display system that has been developed for a long time is viewed through auxiliary equipment. On the other hand, the virtual reality system uses a variety of different types of sensors to make the audience immerse into the scene created by the computer and realize the interaction. The ultimate goal of virtual reality is to meet the needs of the audience as much as possible through the system composed of computers and sensors. [0003] The main components of a traditional stereoscopic display system include a stereoscopic display, red and blue stereosco...
