基于图像的虚拟现实技术在驾驶模拟器中的应用

The Application of Image-Based Virtual Reality in Drive Simulator

近年来基于图像的虚拟现实技术发展迅速,它很好弥补了基于图形的三维虚拟场景构建方式中的不足。基于图像的虚拟现实技术主要包括基于图像的建模和漫游技术,本文将基于图像的漫游技术应用于汽车驾驶模拟器的视景系统,实现了一定区域内逼真的场景漫游。本文首先利用图像拼接技术实现单视点宽角度漫游,再通过图像插值和视图变形技术实现连续的多视点漫游。

Image-Based Virtual Reality is developing rapidly because it solved the problems of Graph-Based 3D Rending Technology. Image-Based Virtual Reality includes Image-Based Modeling and Image-Based Navigation. In this paper, Image-Based Navigation was applied in the view system of Drive Simulator to realize living navigation in specified region. This paper applied Image Mosaics to realize wide-angle navigation in a view point and applied Image Interpolation and View Morphing to realize multipoint navigation.
