城市空间三维数据采集系统关键技术

Research of the Key Techniques for the City Spatial 3D Data-Collection System

城市空间三维数据的快速获取是信息化城市建设的基础。主要论述了城市空间数据采集的关键技术,通过激光测距、GPS定位以及IMU定向三大技术的系统集成,实现城市空间三维数据的快速获取。最后,通过实验论证了采集系统应用的可行性与实用性。

The rapid acquirement of the city spatial 3D-data is the fundament of the city information infra-construction.This paper mainly dwells on the key techniques of the city spatial data collection system and the three technology systems（LIDAR,GPS and IMU） are integrated to realize the rapid data-collection of the city spatial 3D-information.At last,the feasibility and practicality of the whole system is testified by the factual experiences.
