数字城市中大楼的计算机三维重建技术

在现实生活中，常常需要将大楼景观实现计算机化，以虚拟现实的方式实现动态展示和交互式观察。其实现的技术很多，但效果差别很大。通过研究，本文获得了一种最佳的技术，动态展示和交互式观察的方便程度和灵活性最高。主要是通过贴图技术和多维材质技术、面剥离法和面缝合法，并配合图像处理技术，实现大楼的快速三维重建。利用该方法，我们实现了泉城路和山东建筑工程学院老校区的大型三维场景的重建工作。该技术可应用于三维立体城市规划、旅游、数字化地球等方面。

Computer realized three-dimensional reproducing technology of buildings in digital city

In real-life of today, the realization of dynamic show and mutual observation of buildings on computer by virtual reality is often necessary. Many methods could be chose to establish virtual reality but the effects are very different. In this paper, we introduced realizing technology with the best convenience and flexibility in dynamic show and mutual observation. The affixing picture, multidimensional material technique and surface detaching, stitching method were used combined with image-processing to reconstruct the three dimensional images of Quancheng Road and SUAI'(Shandong University of Architecture and Engineering) old campus. The method could be applied in many fields like three-dimensional city layout, tour and digital globe etc.
