摘　　要：引入自然交互这一人机交互领域的最新概念,基于Kinect传感器强大的人体识别与关节点空间运动跟踪及坐标定位能力,提出采用体感人机交互技术在三维虚拟空间中进行公路线形几何设计的方法,并给出了公路真三维设计系统架构.讨论了采用手势进行公路设计的流程以及手势识别、视角控制、线形实时动态交互优化编辑等功能模块的功能设计与相互关系.并采用微软SDK和Google Earth作为第三方软件,开发了系统原型并进行实验,实现了人机交互手段与公路设计平台由二维向三维转变,验证了基于体感交互的公路真三维设计方法的可行性.In this paper,by introducing the concept of the natural interaction which is the latest achievement in the human-computer interaction research and based on the powerful capabilities of the Kinect sensor to identify human body parts and to track the joint space motion as well as to position the joint coordinates,a method to adopt the motion sensing-based human-computer interaction technique to carry out the geometric design of highway alignments in a three-dimensional virtual space is put forward,and a system framework of the true three-dimensional highway design is established. Then,the process of adopting gestures to design highways is discussed. Moreover,the paper describes the functional design of functional modules and the relationships among these modules,which includes the gesture recognition,the perspective control,the real-time dynamic interactive alignment optimization,etc. Finally,with Microsoft＇s SDK and Google Earth as the third-party software,a system prototype is developed and the corresponding experiments are performed,thus realizing the goal of transforming the two-dimensional nature of both the human-computer interaction and the highway design platform into the three-dimensional nature,and the feasibility of the proposed method is accordingly verified.
