Computational Photography for Capturing Virtual Environments

用于导航、训练和计算机动画的基于图像的虚拟环境很有吸引力，但生成高质量和物理上合理的大型环境仍然超出了今天的技术。许多研究挑战仍然存在，包括在捕获期间光照变化的情况下使基于大图像的环境保持一致，并在不同的光照下显示它们。另一个主要挑战是赋予基于图像的环境一些交互物理行为，例如，对交互力的响应。基于图像的虚拟环境必须变得更加丰富，以提供这些新的功能，这些功能将使计算机动画行业、移动导航和安全、资产监控和基于模拟的培训等领域的新应用成为可能。

Image-based virtual environments for navigation, training and computer animation are attractive, but generating high-quality and physically plausible large environments is still beyond today's technology. Many research challenges remain, including making large image-based environments consistent despite changes in illumination during capture and displaying them afterwards under different illumination. Another major challenge is to give image-based environments some interactive physical behaviour, e.g., a response to interactive forces. Image-based virtual environments must become richer to provide these new capabilities which will enable novel applications in the computer animation industry, in mobile navigation and in security, in monitoring of assets and in simulation-based training.
