Watershed water surface mixed drawing method and system, electronic equipment and storage medium

Abstract

The invention discloses a watershed water surface mixed drawing method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining original section observation data of a target watershed and performing multi-level data index storage; performing spatial interpolation on the target drainage basin according to the original section observation data, constructing a water surface grid, obtaining the terrain elevation of the target drainage basin, and constructing a water surface model of the target drainage basin; according to the drawing shapes of the multiple water surface drawing models, dotted models, linear models and planar models are sequenced, and according to the model sequencing sequence, obtaining a mixed drawing model through sequential drawing; superposing the mixed drawing model to a target drainage basin water surface model to obtain a drainage basin water surface visualization model; performing spatial interpolation on the target drainage basin according to the spatial change, performing time interpolation according to the time change, performing dynamic frame interpolation drawing, and achieving drainage basin water surface one-map mixed rendering. According to the invention, through sorting and hybrid rendering of various models, visual overlapping and shielding can be reduced, and the rendering effect and the rendering efficiency are improved.

Description

technical field [0001] The present invention belongs to. The invention belongs to the field of computer visualization, and in particular relates to a mixed drawing method and system of water surface in a river basin, electronic equipment, and a storage medium. Background technique [0002] In recent years, global climate change has been disordered, resulting in frequent occurrence of extreme natural disasters. Rainstorm and flood disasters are one of the common major natural disasters in my country. Among them, floods in the Yangtze River and Yellow River basins have brought great threats to people's lives and property safety due to their wide range of influence, rapid change speed, and large population along the river basins. . With the development of information technology, the concept of "digital watershed" came into being. "Digital River Basin" combines the latest geographic information system, virtual reality, cloud computing and other technologies to collect, process...
