HERON LITE移动测量系统在房地一体中的应用

Application of HERON LITE mobile measurement system to the integrated premises and land

在开展房地一体项目时,传统的测量技术已不堪重负,即时定位与地图构建(SLAM)技术在移动测绘方面具有较好的应用,其不依托GNSS信号可以对室内和室外的地面水平环境进行地图构建和环境建模。文中利用HERON LITE便携式移动测量系统开展房地一体测量实验,介绍测图流程、数据内业处理与点云成图,并分析其点云精度,对比各种作业方式的效率。实验证明,该系统在保证精度的同时,可以提高房地一体测量效率。

When the integration of premises and land project is carried out,the traditional surveying technology is overwhelmed.The simultaneous localization and mapping(SLAM)technology has good applications in mobile surveying and mapping.It does not rely on GNSS signals,map construction and environment modeling can be achieved for indoor and outdoor ground horizontal environment.The paper uses the HERON LITE portable mobile measurement system to conduct an integrated measurement experiment on premises and land.The paper introduces in detail the mapping process,data internal processing and point cloud mapping,analyzes its point cloud accuracy,and then compares the efficiency of various work methods.Experiments have proved that the system can greatly improve the measurement efficiency while ensuring accuracy.
