摘要
为了提高地面三维激光扫描系统作业效率及成果质量,以RIEGL VZ-400地面三维激光扫描系统为研究对象,介绍了扫描系统的主要组成和工作原理,推导了系统的数学模型;分析了扫描系统内外业一体化作业流程,提出了提高系统测量精度、作业效率和成果质量建议;对天安门广场华表古建筑进行了三维扫描测量实验,给出了数据采集、数据处理和模型重建的基本方法和结果;实验结果真实细致的反映了华表的三维形貌和纹理特征。
In order to improve the operational efficiency of 3D terrestrial laser scanning system and the results quality, the major component and the principle of the RIEGL VZ-400 3D terrestrial laser scanning system are presented and the sys tern mathematic model is derived. Then, the Integrated Operational procedures of the system are analyzed. Besides, im-proving system measurement accuracy, operational efficiency and the results quality recommendations are also presented. Finally, the Ornamental Columns in Tiananmen Square are measured and reconstructed. The basic methods and the re sults of data acquiring, data processing and 3D model reconstruction are provided. The experimental results show that real and detailed three-dimensional morphology and texture features of the Ornamental Columns are reflected.
