Design method and VR (Virtual Reality) system based on virtual reality in automobile product development process

Abstract

The invention discloses a design method and a VR (Virtual Reality) system based on virtual reality in an automobile product development process. The VR system comprises curved surface design software, a transformation plug-in, a graphic rendering system, a VR hardware kit, a driving and riding simulation cockpit, VR wearing equipment and large space multi-people sensing equipment, wherein the transformation plug-in transforms and outputs a digital model manufactured by the curved surface design software into a head-mounted display to present a virtual reality scene; the driving and riding simulation cockpit is cooperated with the VR wearing equipment to sense the position of a person in an automobile from the perspective of first person; and the VR wearing equipment controls to label and express a design change direction, identify a modeling feature line revision direction and achieve a purpose on revising the digital model in the curved surface design software under the environment through the transformation plug-in by means of the VR wearing equipment and a control handle in the virtual reality scene. By use of the VR system and the design method, virtual vision experience which surpasses a CAVE type can be realized without utilizing large space environment, and the requirements of the market on system miniaturization, low cost and use convenience are met.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a design method and a VR system based on virtual reality in the development process of automobile products. Background technique [0002] With the increasing development of VR technology, the VR system used for automotive product development has become more streamlined and efficient from the large size, and the virtual reality experience has become more real. The VR virtual reality system has also broken through the original CAVE system architecture. The original CAVE system architecture generally has the following problems: [0003] 1. The CAVE system architecture occupies a huge area, the system structure is complex, the hardware is various, and the equipment is expensive; [0004] 2. The CAVE system architecture does not provide a good sense of immersion, and its experience is more like a 3D movie; [0005] 3. The software interface of the CAVE system architecture is...
