A vision-based augmented reality system device

Abstract

The invention discloses a vision-based augmented reality system device. The device includes a virtual scene generator, a see-through head-mounted display, a head orientation tracking device for tracking the user's observation line of sight, a positioning device and an interactive device for aligning the virtual scene with the real scene. In the system, the virtual scene occurs The device adopts OpenGL 3D graphics library to be responsible for the modeling, management and drawing of the virtual scene; the see-through head-mounted display is selected as the display device that integrates the virtual environment with the real environment; the head position tracking device adopts the method of computer vision, through the The image is processed and recognized to track the changes of the user's line of sight, so as to realize the matching between the user's observation coordinate system and the virtual scene coordinate system. The device of the invention can perform real-time interaction, has extremely high interaction sensitivity, and has excellent projection expression.

Description

technical field [0001] The invention relates to the field of interactive projection, in particular to a vision-based augmented reality system device. Background technique [0002] With the rapid development and popularization of information science and technology in today's society, media forms and carriers have been greatly enriched, and people's requirements for this are getting higher and higher. Gradually eliminated by consumers and many merchants, new media has gradually become the main way of art display and commercial display, and has shown strong development potential. The use of new media technology is a new media art display platform that can actively attract consumers' attention and realize user interactive experience. [0003] The form of traditional media is single, and the operation is complicated. Users can only obtain information through vision and hearing, which greatly affects the effect of display and publicity. However, most of the existing new media de...

Problems solved by technology

[0003] The form of traditional media is single, and the operation is complicated. Users can only obtain information through vision and hearing, which greatly affects the effect of display and publicity.

However, most of the existing new media devices do not have interactivity or the interactivity is very poor, and the sense of participation is not strong, which seriously affects the user experience
