Development of a 1:1 Scale True Perception Virtual Reality System for design review in automotive industry

摘要

The recent improvements of Virtual Reality (VR) technologies makes it feasible for automotive design reviews to be carried out in a virtual world. Design review with virtual prototypes could reduce costs by eliminating the need to build physical prototypes, help speed up the design process, and enable the simultaneous examination of different design options. However, the most important challenge to address is whether a true 1:1 scale representation of the vehicle can be achieved in VR; whilst such claims are frequently made, how this is achieved is not reported in the research literature. In this study, a VR system with 1:1 scale true perspective display was created and calibrated using a large stereoscopic screen and optical tracking system. Various vehicle models of differing fidelity were used to test the capability of the system and ideal sizes of model identified. This paper also reports the use of several virtual tools for the design review process, which augment the immersive experience of the observer
