英文摘要 | Virtual-Real fusion is also called augment reality (AR for short), mixed reality (MR for short).It's a new technology along with the application of virtual reality technology. It applies computer vision, computer graphics and other technology to make the real world and the graphs, images and voices produced by the computer overlapped, make them converge seamlessly and complement or enhance each other. Users immerged in it like being there, they can handle the virtual world and the real world at the same time telling no difference .Following application goes in depth and width, as well as notepads, iPads, intelligent mobile phones and other electronic equipments are more popular, people are tend to the portable, personalized, fashionable, intelligent, interactive systems. So the integration of different hardware and various software applications is especially emergent. Although some progress have been made in this field, the mature systems depend on their unique platforms and always expensive. While the physical equipments are also tight coupling, which is very difficult to fit the new application. Thus, developing a low cost, general, more applicable and more extensible application platform is magnificent to the complicated requirements in the future. Based on these, this paper goes in for taking Delta3D an open source game engine as an open general virtual-real fusion system developing and integating platform to meet these requirements. The goal of this paper is to analyze the feasibility of taking Delta3D as a general virtual-real fusion system developing platform from aspects of open, general and extensibility. As an example, we integrate the high accurate head positioning system into Delta3D. It implements the virtual-real system interactive equipments and software seamless integration and intuitively demonstrates the data variation by the application case. High accurate head positioning system traces the positon and pose in the real world. Application combines of the virtual scenes made by STAGE, integration of high accurate head positioning system, interaction with the real world, data processing, displaying data variation intuitively by skinned mesh animation technology and drawing the virtual-real fusion scenes in real time. Firstly, the paper describes the definition of virtual-real fusion, delicately analyze the research and application situation and achievements both at home and abroad. And then discuss the key technology about virtual-real ... |
