本文提出了一种新的方法来绘制视图，特别是那些大规模的场景，如广阔的城市景观。我们的方法的主要贡献是，我们能够很容易地渲染任何视图从任意点到任意方向在地面上的虚拟环境。我们的方法属于家庭的工作，采用全光功能;然而，与其他作品的这种类型，这种特殊的方法允许我们渲染一个新的观点，从几乎任何一个点的平面上的图像被拍摄。另一方面，以前的方法在可重构区域方面有一些限制。因此，当合成一个大规模的虚拟环境，如城市，我们的方法有很大的优势。我们的方法的应用之一是在ITS域的驾驶模拟器。我们可以从沿着一条车道行驶所拍摄的图像中生成道路上任何车道上的任何视图。我们的方法，使用一个全方位的相机或类似类型的测量设备，首先通过沿着一条直线运行来捕获全景图像，记录每个图像的捕获位置。在绘制时，该方法将存储的全景图像分成垂直狭缝，根据我们的理论选择合适的狭缝，并将它们重新组合以生成图像。该方法可以制作具有步行能力的虚拟城市。在这个虚拟的城市里，人们可以相当自由地移动和观看。在本文中，我们描述了一种新的全光函数的基本理论，分析了该理论的适用范围和生成图像的特性，并演示了一个完整的工作系统，使用室内和室外场景。
This paper presents a new method for rendering views, especially those of large-scale scenes, such as broad city landscapes. The main contribution of our method is that we are able to easily render any view from an arbitrary point to an arbitrary direction on the ground in a virtual environment. Our method belongs to the family of work that employs plenoptic functions; however, unlike other works of this type, this particular method allows us to render a novel view from almost any point on the plane at which images are taken. Previous methods, on the other hand, have some restraints concerning their re-constructable area. Thus, when synthesizing a large-scale virtual environment such as a city, our method has a great advantage. One of the applications of our method is a driving simulator in the ITS domain. We can generate any view on any lane on the road from images taken by running along just one lane. Our method, using an omni-directional camera or a measuring device of a similar type, first captures panoramic images by running along a straight line, recording the capturing position of each image. When rendering, the method divides the stored panoramic images into vertical slits, selects some suitable ones based on our theory, and reassembles them for generating an image. The method can make a virtual city with walk-through capabilities. In that virtual city, people can move and look rather freely. In this paper, we describe the basic theory of a new plenoptic function, analyze the applicable areas of the theory and the characteristics of generated images, and demonstrate a complete working system using both indoor and outdoor scenes.
