Abstract

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.

Key words: steep reservoir, hydrologic and sediment monitoring, BPSL, point cloud data
