Development of communication system with realistic sensation

已经开发了几种用于从真实摄影图像合成虚拟环境的系统。这种类型的系统可以被认为是生成虚拟世界的另一种方式，与使用计算机图形学处理3D CAD模型相反，该系统还可以很容易地提供呈现3D空间的非常逼真的感觉。例如，作者开发了一个名为“虚拟穹顶”的系统。然而，该系统仅允许用户从固定视点查看先前记录的图像。这意味着当用户在虚拟环境中连续改变视点时，不允许用户自由移动。如果没有任何特殊的算法来向用户提供来自所有可能视点的图像，将需要大量记录的图像数据。使用这个开发的系统，我们可以在不使用非常复杂的3D模型的情况下，以合理的成本实现逼真的虚拟世界。

Several systems have been developed for synthesizing virtual environments from real photographic images. This type of system can be considered as an alternative way of generating virtual worlds as opposed to using computer graphics with 3D CAD models, This system can also easily provide very realistic sensations of being present 3D space. For example, the authors have developed a system called the "Virtual Dome" . However, this system only allows the user to look around at previously recorded images from fixed viewpoints. This means that the user is not allowed to move around freely while changing viewpoints continuously in the virtual environment. Without any special algorithms to provide the user with images from all possible viewpoints would require enormous amounts of recorded image data. Using this developed system, we could implement realistic virtual worlds at a reasonable cost without using very complex and complicated 3D models.
