摘要
数字摄影测量学与现代信息科学的结合产生了数字三维地形技术,使人们能够借助计算机技术在三度空间完成对地形形态数字化的真实描述。获取数字三维地形成果主要涉及数据源、采集模式和生产流程个方面。可视化与虚拟现实技术使数字三维地形成果具有真实的效果3和强烈的临场感。查询、分析、仿真等功能的实现使数字三维地形技术有广泛的应用价值。
The technology of 3D digital topography, being developed with combination of digital photogrammetry and modern information science, helps people to describe truly in digital the topography in the 3D space with the aid of the computer technology. To gain the 3D digital topographic results mainly involves three aspects such as the data source, the processing mode and the production procedure. Visualization and the technology of virtue reality make the digital 3D topography results have effects as if it was physical and strong on-the spot sense. With the realization of functions such as retrival, analysis and simulation, the digital 3D topography technology has extensive prospects of application.
