摘要
三维激光扫描技术使传统的工程测量从静态的单点测量发展到动态的跟踪测量与三维立体测量领域。从用户角度出发,简要介绍了地面固定式三维激光扫描仪的基本原理、主要特点、性能指标,阐述了获取高精度三维扫描数据成果的过程。不是利用详尽的公式和实验进行精度分析,而是着重分析从采集数据到点云数据处理过程中数据质量的误差来源,详细分析其中原因,并且在已有研究分类的基础上,重新进行归类,最后介绍了国内外产品。
Terrestrial laser scanning technology enables the traditional measurement from a single point of measurement of static to dy -namic tracking and three -dimensional measurement .From the user perspective , this paper describes the basic working principle of Terrestrial laser scanning, main features, performance index.Process of getting 3D laser scanner data the high -precision is intro-duced.It is not analysis on accuracy by using detailed formula and tests , but emphatically analysis source of errors of quality of data of Terrestrial Laser Scanners .And reclassifying is based on existing research of classification .Finally, this paper introduces domestic and foreign products .
