OsgEarth Stereoscopic Vision Generation Method for HMD-based Virtual Reality

doi:10.16182/j.issn1004731x.joss.18-VR0700

Abstract

Abstract: The technology of immersive virtual reality based on helmet mounted display (HMD) has become a focus of study, however, its visual content is mainly produced through commercial game engines. OsgEarth is an open-source, state-of-the-art and widely used digital earth simulation system. Based on this, we studies the stereoscopic vision generation method for global virtual terrain environment, mainly focusing on: stereoscopic vision theory; construction of global high-precision virtual geographical environment; calculation of binocular view frustrum; system integration. The proposed method is verified under the hardware conditions of PC and HTC VIVE, which can generate stereo images of the global virtual geographic environment correctly, and can allow users to have immersive experience of roaming the earth.

Key words: helmet mounted display (HMD), virtual reality, virtual geographic environment, osgearth, digital earth, stereoscopic vision, HTC VIVE
