三维激光扫描在地形测量中的应用

Application of 3D Laser Scanning in Topographic Survey

三维激光扫描技术是近代广泛应用于建设工程的一种集光、机、电及信息技术于一体的综合测量技术,得益于其现场海量点云的快速采集和分析能力,为地质检测提供了一种全新的、可实施手段。三维激光扫描技术作为近年来测绘领域的热点技术,因其快速、精确、无接触的特点,应用越来越广。然而该技术具体的运用还存在时间较短的问题,我国当代将三维激光扫描技术运用在地质工程勘探方面起步较晚,还有许多问题以及难点需要去解决。

Three-dimensional laser scanning technology is a comprehensive measurement technology that integrates optical,mechanical,electrical and information technology widely used in construction projects in modern times.It benefits from its rapid collection and analysis capabilities of massive point clouds on site,and is a geological inspection provides a new and implementable means.As a hot spot technology in the field of surveying and mapping in recent years,3D laser scanning technology has become more and more widely used due to its fast,accurate,and non-contact characteristics.However,the specific application of this technology still has a short period of time.The application of 3D laser scanning technology in geological engineering exploration in China is a late start,and there are still many problems and difficulties that need to be resolved.
