Abstract

Abstract: This paper takes seven reservoirs in Henan province as research objects to obtain the image-free LiDAR cloud data and orthophotomy data in the reservoir region. A total of 47 sorties are flown with a total area of 950 km², the reservoir protection line of 2442 km and the management line of 1886 km.This paper discusses the selection of equipment, setting of flight parameters, equipment checking, filtering of point cloud data, point cloud refinishing, accuracy checking and other links.The results show that the method has the advantages of high accuracy and low cost compared with traditional methods.The method provides a new way to obtain data for delimitation and fine management of reservoir region boundaries.

Key words: LiDAR, reservoir, DEM, point cloud, high-precision
