地面三维激光扫描仪角度测量检校方法研究

Research on Angle Measurement and Calibration Method of Ground 3D Laser Scanner

使用地面三维激光扫描仪时,由于速度太快、使用寿命长等原因,其精确度会降低,故需检查地面三维激光扫描仪是否精确。在分析地面三维激光扫描技术原理及误差来源的基础上,针对Leica C10高精度地面三维激光扫描仪测角误差过程设计了检校实验,以Leica TS30高精度全站仪测量数据为参照,得到该仪器的水平角和竖直角测量误差。

When the ground 3D laser scanner is used,its accuracy is reduced due to too fast speed,long service life and other reasons,and it is necessary to check whether the ground 3D laser scanner is correct.Based on the analysis of the principle and error source of 3D laser scanning technology,a calibration experiment is designed for the angle measurement error process of Leica C10 high-precision 3D laser scanner.The horizontal angle and vertical angle measurement errors of the instrument are obtained by referring to the measurement data of Leica TS30 high-precision total station.
