地面三维激光扫描仪扫描精度检定

三维激光扫描技术主要用于获取被测物体表面三维坐标信息,具有速度快、数据量大、精度高、可自动连续测量等优势,广泛应用于测绘工程、文物监测与保护、城市规划等技术领域。然而,我国对于三维激光扫描仪检定技术研究较为欠缺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Trimble GX200扫描仪的扫描精度进行检定。

Scanning Accuracy Verification of Terrestrial 3D Laser Scanner

Application of 3D laser scanning technology in three-dimensional coordinate information of the measured accesshas the advantages of fast speed,large amount of data,high precision, automatic, continuous measurementand other advantages,is widely used in the technical field ofartifacts detection and protection,city planning,etc.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 scanning precision of the GX200 Trimble scanner is verified.
