Aerial Survey and Scanning Point Cloud Data Acquisition & Modeling Technology for Hydropower Engineering

Through a systematic research on the application of methods for acquiring point cloud data concerning aerial surveying and laser scanning of modern water conservancy projects, a kind of advanced aerial photogrammetry and laser point cloud scanning and acquiring technology is proposed and tools are developed for processing of point cloud data of modern water conservancy projects and reverse modeling technology. Combined with a specific hydropower project, detailed application is carried out step by step from the aspects of station distribution and acquisition of point cloud data, splicing and redundancy removal processing of data and establishment of 3D models and reverse 3D modeling is implemented, realizing the basic modeling for informationization of modern hydropower projects and developing a new method and thinking for surveying work of hydropower projects.
