摘要
扩充现实 (AugmentedReality)使观察者能够同时看到真实世界以及扩充了真实世界的、来自于计算机模型的信息 ,从而具有更丰富的信息空间。与传统虚拟现实相比 ,它具有更强的真实性 ,大大提高了可视化效率。提出了基于透视的AR技术在土木工程可视化中的应用 ,论证了基于透视表示的AR方法及其对大坝工程的应用。结果表明AR技术可以广泛应用于大型水利工程建设的仿真、城镇与环境规划、虚拟漫游系统、环境评价等。
Augmented Reality(AR) is a technology by which a user's view of the real world is augmented with additional information from a computer model,and thus more information spaces are shown. Compared with traditional virtual reality, it can not only present more realistic results, but also greatly raise visualizing efficiency. AR is one of advanced research projects in the computer research field. In this paper, the application of perspective based AR to the visualization of civil engineering is reported, and AR method based on perspective representation as well as its application to a rock earth dam is discussed. The results show that AR is a key point converting scientific technique into productivity. And it can be used in the simulation of large hydraulic engineering, city planning, virtual reality and environmental evaluation.
