摘要: 针对陡岸水库岸坡度大、地形狭窄复杂、植被覆盖度高、水文泥沙监测精度要求高,且传统人工走测难度大、效率低、风险高的问题,本文提出了移动背包三维激光扫描系统观测方法,并以白鹤滩水电站库区典型河段为例,开展了移动背包三维激光扫描系统的应用试验研究。定性定量成果表明,移动背包三维激光扫描系统测量平面中误差为0.024 m,高程中误差为0.044 m,相对面积较差为0.24%,精度符合技术要求,较人工走测工作效率提高3.75倍,十分适用于陡岸水库监测。

Abstract: Aiming at the problems of steep bank and reservoir bank slope, narrow and complex terrain, high vegetation coverage, high monitoring accuracy of hydrology and sediment, and the difficulty, low efficiency and high risk of traditional manual measurement, this paper proposes a 3D laser scanning system observation method with mobile backpack.Taking the typical reaches of Baihetan hydropower station as an example, the application test of the mobile backpack 3D laser scanning system is carried out.The results show that the moving backpack 3D laser scanning system has a median error of 0.024 m, a median error of 0.044 m, and a relative area difference of 0.24%. The accuracy meets the technical requirements, and the work efficiency is 3.75 times higher than that of manual walking, and it is more suitable for the monitoring of the steep bank reservoir.
