天宝GX200地面三维激光扫描仪鉴别率检定

三维激光扫描技术是一种新兴的全自动、高精度测量技术。三维激光扫描仪能够在短时间内大面积、高密度地获取目标的空间点云数据,逼真细腻地描述目标表面。三维激光扫描仪作为一种测量仪器,本身也存在误差。目前,我国三维激光扫描仪检定技术较为薄弱且尚未制定系统的技术规范。本文结合国内外对三维激光扫描仪性能检定的理论方法,设计相应的实验方案,对所用Trimble GX200扫描仪的鉴别率进行检定。

Verification for Discrimination of Trimble GX200 Terrestrial 3D Laser Scanner

3D laser scanning technology is a new kind of Automatic surveying technology with high precision.A 3D laser scanner can capture the spatial data of point cloud in large dimension and high density within a short time, describing the surface vividly and exquisitely.However,error exists within this measuring apparatus,as an instrument itself.However, our country is lack of the three-dimensional laser scanner calibration technology, and has not yet established the technical specifications of the system.In this paper, based on the theory and method of the three-dimensional laser scanner performance verification, the corresponding experimental program is designed, and the discrimination of the GX200 Trimble scanner is verified.
