【摘要】 当前“数字地球”的研究要求对地球空间进行三维描述，本文将逆向工程技术引入三维地理信息系统中，运用 STL模型将建模、显示和加工有机结合起来，实现了对地球表面三维测量数据的快速模型重建，并采用基于生长机制的分层制造技术对模型进行快速重建，为真实地面模型的制作提供了有效的解决途径。更多还原

【Abstract】 Digital earth research requests three－ dimension description to the space of earth in geometry information system. In this paper reverse engineering technique is introduced to 3D GIS, model of the earth is reconstructed from measured earth surface points based on combination of measurement, modeling and manufacturing through STL standard. An actual earth model is made in laminated object manufacturing system based on growth mechanism. Method introduced above provides full solution to generate actual physiognomy model from 3D measured data.更多还原
