车载激光扫描技术在三维地籍测量项目中的精度分析
|
摘要
利用车载激光扫描系统对实验区域进行三维地籍测量,针对基于MLS(车载激光扫描系统)数据的三维地籍建模进行了精度分析。实验结果表明,MLS数据能够精确提取建筑物的外部结构以及特征点三维信息,且相对于传统的测量模式具有高效便捷的优点,精度指标能够满足城市加速发展引起的地物地貌变化更新的要求,在三维地籍测量中具有很好的适用性。
In this paper, we used the mobile Laser-scanner(MLS) to do 3 D cadastre surveying of the experimental area, and analyzed the accuracy of 3 D cadastre modeling based on MLS data. The result shows that MLS data can extract the external structure of the building and the position of feature points precisely. What's more, the method with MLS data is more efficient than the traditional way, which can meet needs of fast development which caused the landscape changing. The method with MLS data has a good adaptability.
