Research on multi-source water conservancy 3D modeling method for reservoir watershed
Aiming at the complex operation and high cost of underwater terrain modeling by using Lidar,sonar and other sensors in 3D visualization modeling in large-scale rivers,the multi-source 3D model fusion method is adopted to build a real terrain model for Yuetang Reservoir watershed on the basis of realistic terrain model built by basic surveying and mapping results.Firstly,the 3D modeling technology of oblique photography is used for the real scene modeling of key water conservancy projects,and the component level modeling of important control units is carried out by professional modeling software.Then,the 3D real scene model of Xupu River is formed by combining the existing channel section data with river surface vector data.Finally,the multi-source reality model is fine-tuned and mutually verified by human-computer interaction,and the multi-source 3D model of Yuetang Reservoir watershed is accurately integrated and constructed.The research results provide visual model basis and decision support for the forecast operation and flood risk analysis of channel reservoir.
