Rapid and Automatic Reconstruction of Large-scale Areas

近年来，人们对现实虚拟世界的需求越来越大，虚拟世界代表了大规模的现实世界区域，包括地形、建筑、树木、汽车等。已经报道了许多采用这种逼真的虚拟表示的成功应用，包括用于培训应急人员的高级灾害管理模拟、用于城市规划和发展的施工前就地可视化新结构，以及故事情节发生在真实地点而不是虚构地点的电脑游戏。举个例子来说，育碧的《刺客信条》包含了许多文化遗产（尽管有些保存得并不完美），如圣索菲亚大教堂、加拉塔、Kyrenia和利马索尔的城堡等。

In recent years there has been an increasing demand for realistic virtual worlds representing large-scale, real-world areas comprising of terrain, buildings, trees, cars, etc. Many successful applications employing such realistic virtual representations have already been reported including advanced disaster management simulations for the training of emergency response personnel, visualizing new structures in-situ prior to construction for urban planning and development, and computer games where the storyline takes place in an actual rather than fictional location. For example Ubisoft’s "Assassin’s Creed" contains numerous cultural heritage sites [albeit some of them not in perfect condition], such as the Hagia Sophia, the Galata tower, the castles in Kyrenia and Limassol, etc.
