建筑物是城市景观中一个重要组成部分, 因此快速自动实现城市建筑物的三维可视化对于建立数码城市具有重大意义. 针对传统三维建模人工劳动强度大、自动化程度低和花费高等问题, 提出了一套自动化程度较高的基于线、面信息的城市建筑物框架轮廓快速三维重构方法. 通过普通数码相机获取影像数据大大降低了实际应用成本, 而且采用线面基元进行三维重构相比于经典的点云重构方法不仅提高了效率, 而且获得了清晰的三维边缘轮廓. 通过实验验证了方法的有效性和可行性

Building is an important component of urban landscape,therefore,how to rapidly realize 3D visualization of city buildings has a great significance for constructing cyber city.Aiming at some problems in traditional 3D modeling,such as intensive manual labor,low degree of automatization and high cost etc,this paper presents a high feasible and high automatic approach to auto-reconstruct 3D framework outline based on line and plane information.The approach gets image data by common digital camera,which reduces the cost of the practical application.Moreover,distinguishing and clear 3D edges also c...
