LiDAR测量技术在高陂水利枢纽工程中的应用

Application of LiDAR Measurement Technology to Gaopi Water Control Project

水利枢纽工程通常具有范围大、地形复杂等特点,应用机载激光雷达(LiDAR)测量技术能快速获取大面积目标空间信息,提高测量效率。机载激光测量(LiDAR)技术是直接采集并获取数码影像数据和激光点云数据,在此基础上经过后期加工和处理,得到DSM、DEM、DOM等数据产品的测量技术,在一些相关专业软件的辅助下,还可以其制作其他数据产品,如三维电子沙盘,生成测区三维景观,可以大大提高水利设计的直观度。

Dam project area has features such as a large measurement range and complicated terrain. Then the application of airborne laser radar measurement technology(LiDAR) can quickly obtain target spatial information in a large area and improve measurement efficiency. This technology is a direct digital image capture and can obtain data and laser point cloud data. On the basis of this post-processing DSM, DEM, DOM and other data products can be gained. With some specialized software-related aid, other different data products such as three-dimensional electronic sand table can be made, a three-dimensional landscape survey area generated, which can greatly improve the visual design in water conservancy.
