摘要
水库、山地、矿区等复杂环境的地形测绘已实现由传统测绘向机载LiDAR、倾斜摄影、遥感技术等新型测量方式转变,能在短时间、大范围内高效地完成目标区域内的测绘任务,机载LiDAR系统能快速获取高精度的3D点云与匹配的影像数据,生成高精度的DOM、DEM、DLG与3D模型。本文通过机载LiDAR系统在水库地形测绘中的应用实例,介绍和总结了生产技术流程,验证了地形图产品精度,提供了在水库中应用的范例,为高效地测量复杂地形提供标准化流程。
The topographic surveying and mapping of complex environments such as reservoirs,mountains,and mining areas has realized the transformation from traditional surveying and mapping to new surveying methods such as airborne LiDAR,tilt photography,and remote sensing technology.It can efficiently complete the surveying and mapping tasks in the target area in a short time and on a large scale.The airborne LiDAR system can quickly obtain high-precision 3D point clouds and matching image data,and generate high-precision DOM,DEM,DLG and 3D models.Through the application examples of airborne LiDAR system in reservoir topographic surveying and mapping,the article introduces and summarizes the production technology process,verifies the accuracy of topographic map products,provides examples of application in reservoirs,and provides a standardized process for efficient and complex topographic surveying.
