当今的三维（3D）虚拟环境（VE）通常基于纹理多边形3D模型，其表示虚拟世界的外观和几何形状。然而，一些应用领域需要其他图形范例，这是目前没有充分解决的3D用户界面。我们介绍了一种新的方法，技术的人-机器人远程呈现设置，允许人类观察员探索VE，这是一个基于点云的真实的世界的3D重建。这样的点云虚拟环境（PCVE）代表外部环境，并且通常由3D扫描仪获取。我们提出了一个应用场景，其中一个移动的机器人捕获三维扫描的地面环境，这是自动注册到一个连贯的PCVE。该虚拟3D重建显示在沉浸式虚拟环境（IVE）中，在该沉浸式虚拟环境中，用户可以探索PCVE。我们解释和描述的技术设置，这开辟了新的前景，提出一个VE点，而不是一个多边形表示。
Today's three-dimensional (3D) virtual environments (VEs) are usually based on textured polygonal 3D models, which represent the appearance and geometry of the virtual world. However, some application domains require other graphical paradigms, which are currently not adequately addressed by 3D user interfaces. We introduce a novel approach for a technical human-robot telepresence setup that allows a human observer to explore a VE, which is a 3D reconstruction of the real world based on point clouds. Such point cloud virtual environments (PCVEs) represent the external environment, and are usually acquired by 3D scanners. We present an application scenario, in which a mobile robot captures 3D scans of a terrestrial environment, which are automatically registered to a coherent PCVE. This virtual 3D reconstruction is displayed in an immersive virtual environment (IVE) in which a user can explore the PCVE. We explain and describe the technical setup, which opens up new vistas of presenting a VE as points rather than a polygonal representation.
