摘要
随着大型水利枢纽信息化建设的推进,水利枢纽的管理效率得到很大程度的提升。但由于水利枢纽工程附近环境的复杂、水域面积大、控制点稀疏等因素的影响,利用机载LiDAR采集数据时会遇到地面控制测量难度大、航摄困难、寻找同名点困难等技术难题。本文就遇到的技术难题提出相应的解决方案,保证采集的原始数据和经处理之后的制作成果的可靠性,进而保证水利枢纽信息化建设的顺利进行。
With the promotion of information construction of large hydro-project,the management efficiency of hydro-project has been greatly improved.However,due to the complex environment,wide water area,sparse control points and other factors of the water conservancy project,the acquisition of data by airborne LiDAR will encounter major technical difficulties such as difficulty in ground control measurement,difficulty in aerial photography and difficulty in finding the same name points.This paper proposes corresponding solutions to the technical problems encountered,so as to ensure the reliability of the original data and production results,so as to ensure the smooth progress of the information construction of hydro-project.
