Studies on Free-viewpoint Image Generation of Large-scale Outdoor Environments Based on Omni-directional Dynamic Imaging

该项目的目标是利用全方位动态成像来虚拟化大型户外环境。首先构建了全向成像系统，然后结合基于模型和基于图像的方法，开发了基于捕获图像和GPS定位的相机外部参数估计、场景三维重建和自由视点图像生成等算法。最后，开发了增强虚拟的原型系统，并通过向公众开放的实验成功地进行了演示。

The objective of this project is to virtualize large-scale outdoor environments using omni-directional dynamic imaging. Firstly we have constructed omni-directional imaging systems, and then developed a number of algorithms of extrinsic camera parameter estimation from captured images and GPS positioning, 3D reconstruction of scene, and free-viewpoint image generation by integrating model-based and image-based approaches. Finally prototype systems of augmented virtuality have been developed and successfully demonstrated by experiments opened to the public.
