面向手势交互的古建场景快速搭建方法

随着行业快速发展，虚拟现实应用对人机交互方式的要求越来越高，基于非接触手势控制的交互方式日益普及.针对虚拟环境下三维场景构建问题，提出一种面向Leap Motion体感交互设备的古建筑三维场景快速搭建方法.通过Leap Motion获取手部运动数据，实现物理空间与三维空间的实时映射，以及三维模型交互控制与编辑；提出一种基于概率图模型的古建筑构件推荐方法，通过构造贝叶斯网络，实现古建筑各构件之间的概率关系推理；推荐结果实时反馈用户，用户可通过手势选择相应部件，并在三维空间优化模型位置，最终实现古建筑场景的快速搭建.实验证明，相比二维交互方式，本文方法有效利用三维空间信息，并实现模型推荐，因此更加直观、便捷、高效. 

A Rapid Ancient Architecture Modeling Method Facing the Gesture Interaction

With the rapid development of VR industry,the non-contact gesture interactive application is increasingly common.In this paper,a modeling method with Leap Motion was proposed for rapid 3D VR scene developing of ancient architecture.Firstly,hand-motion data were captured with Leap Motion to implement the real time mapping,interactive controlling and editing of physical and 3D space.Secondly,a probabilistic model based recommending method was proposed for building components of ancient architecture.By designing a Bayesian network,the relationships between different components were calculated by probabilistic inference.Finally,several functions were implemented for rapid developing of ancient architecture scene,including returning the recommending results to user in real time,choosing corresponding components by gesture and optimizing the positions in the 3D space directly.Experimental results show that the method can take use of the 3D space information more effectively than traditional 2D style,and much more intuitive,convenient and efficient.
