Application Research of 3D Scanner and(GNSS-RTK)in Complex Terrain Measurement

建设工程进行过程中施工现场地形复杂且呈现动态变化,施工过程中工程实体形度和施工操作对周围环境造成的影响都需要进行监控测量,建设工程施工测量是复杂地形测量的代表。本文讨论复杂地形监控测量过程中利用三维激光扫描测量的快速获取数据,获取到的据利用专业的处理软件处理后获得监控测量物体的立体成像结果,再利用全球导航卫星系统实时动态载波相位差分技术(GNSS-RTK)辅助测量监控点的空间坐标变化以及高程差。两者协同应用可以既快速又准确的进行复杂地形的监控测量。

During the construction process,the terrain of the construction site is complex and dynamic.During the construction process,the progress of the engineering entity image and the impact of the construction operation on the surrounding environment need to be monitored and measured.The construction engineering construction measurement is representative of complex terrain measurement.This paper discusses the fast acquisition data using 3D laser scanning measurement in the process of complex terrain monitoring and measurement.The acquired data is processed by professional processing software to obtain the stereoscopic imaging result of the monitored measurement object,and then the spatial coordinates of the monitoring point are measured byGlobal Navigation Satellite System Real-Time Dynamic Carrier Phase Difference Technology(GNSS-RTK).Change and elevation difference.The synergistic application of the two can quickly and accurately perform monitoring and measurement of complex terrain.
