CAREER: Photorealistic 3-D Modeling of Large-Scale Scenes: Integration of 3-D Range and 2-D Intensity Sensing in a Complete System

该项目的目标是在最少的人为交互和提高计算效率的情况下，自动重建高精度的大规模3D场景的逼真描述。激光距离传感技术的最新发展使获得大规模场景的精确3D扫描成为可能。密集和复杂的3D范围数据集以及高分辨率彩色图像（地面和空中）将被利用。将在距离分割（以处理几何复杂性）、距离与2D图像的自动配准、3D建模、航空摄影融合和可视化等领域进行研究。这项研究将直接影响城市规划、城市设计、防灾、电子新闻、建筑、考古、历史保护和娱乐等领域的应用。将会发展的新颖解决办法将对PI的教育议程及其外联活动产生直接影响。计算机科学、地理、电影和媒体系之间的交叉发展是另一个重点。最后，与博物馆等机构以及专注于3D网站建模和网站建设的公司合作是将本研究从学术环境中推广出去的必要步骤。

The goal of this project is the automated reconstruction of highly accurate photorealistic descriptions of large-scale 3D scenes with a minimum of human interaction and increased computational efficiency. Recent developments in laser-range sensing technology make possible the acquisition of accurate 3D scans of large-scale scenes. Dense and complex 3D range data-sets along with high resolution color imagery (ground and aerial-based) will be utilized. Research will be carried in the areas of range segmentation (in order to handle the geometric complexity), automatic registration between range and 2D images, 3D modeling, fusion of aerial photography, and visualization. The proposed research is going to directly affect applications in the areas of urban planning, urban design, disaster prevention, electronic journalism, architecture, archeology, historical preservation, and entertainment. The novel solutions that will be developed will have a direct effect on the educational agenda of the PI and on his outreach activities. The cross-fertilization between Computer Science, Geography, and Film and Media departments is another priority. Finally, collaboration with institutions such as museums, and with companies concentrated on 3D site modeling and site construction is an essential step for forwarding this research out of the academic environment.
