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是有吸引力的，但是生成高质量和物理上合理的大环境仍然超出了今天的技术。许多研究挑战仍然存在，包括使大型基于图像的环境保持一致，尽管在捕获期间照明发生变化，并在不同照明下显示它们。另一个主要挑战是赋予基于图像的环境一些交互式物理行为，例如，对相互作用力的反应。基于图像的虚拟环境必须变得更丰富，以提供这些新的功能，这将使新的应用程序在计算机动画行业，在移动的导航和安全，在资产监控和基于模拟的培训。

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.
