基于三维激光扫描技术的金矿采空区调查对比分析研究

Comparative Analysis on Gold Goaf Survey Based on Three-dimensional Laser Scanning Technology

本文采用三维激光扫描技术,分别使用手持ZEB-HORIZON型便携三维激光扫描仪和站式天宝TX8三维激光扫描仪2种设备进行井下采空区测量,结合GeoSLAM Hub、RealWorks、Geomagic Studio等相关软件,进行了点云的去噪、抽稀、三维建模等一系列处理,快速有效地计算出采空区的体积、金属量等相关信息。通过手持ZEB-HORIZON型便携三维激光扫描仪和天宝TX8站式三维激光扫描仪数据对比和精度评定,发现手持ZEB-HORIZON型便携三维激光扫描仪更适合远距离、复杂环境的井下测量,经过多站测量后的数据采集更加高效,测量精度更加准确,能够为国土、公安等相关部门提供有力的数据支撑。

In this paper,by using three-dimensional laser scanning technology,using handheld ZEB-HORIZON portable 3D laser scanner and Trimble TX8 station-mounted 3D laser scanner separately,measurement of underground goaf have been carried out.Combining with GeoSLAM Hub,RealWorks,Geomagic Studio and other relevant softwares,a series of processing have been conducted,such as point cloud denoising,thinning and 3D modeling.It can quickly and effectively calculate the volume and metal content of the goaf.Through data comparison and accuracy evaluation between the handheld ZEB-HORIZON portable 3D laser scanner and the Temble TX8 station 3D laser scanner,it is found that the handheld ZEB-HORIZON portable 3D laser scanner is more suitable for remote and complex mine measurement.After multi-station measurement,the handheld ZEB-HORIZON portable 3D laser scanner data collection is more efficient and the measurement accuracy is more accurate.It can provide powerful data support for relevant departments,such as land and public security department.
