Basin terrain 3D printing method and device, electronic equipment and storage medium

Abstract

The invention discloses a watershed terrain 3D printing method and device, electronic equipment and a storage medium. The method comprises the steps that river channel section observation data and surrounding mountain terrain data of a target watershed are obtained; river valley points of the river channel are calculated respectively, and smoothing processing is carried out on each river valley point based on the quartic Hermite spline with parameters to obtain a river valley line; interpolating the riverbed topography along the direction parallel to the valley line, and respectively calculating the position and the water depth value of an interpolation point to obtain riverbed topography data; fusing the mountain topographic data and the riverbed topographic data, and performing standard grid resampling on the riverbed topographic data to generate mountain and riverbed integrated topographic data; 3D printing is carried out according to the mountain land and riverbed integrated terrain data, and a watershed terrain 3D model is obtained. According to the method, riverbed terrain sampling is carried out in the direction parallel to the river valley line, riverbed distribution closer to reality is obtained, mountainous region and riverbed integrated modeling is achieved under the standard grid, and river basin terrain distribution can be expressed more finely.

Description

technical field [0001] The invention belongs to the technical field of digital watersheds, and in particular relates to a method and device for 3D printing of watershed topography, 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. Torrential rain and flood disasters are one of the common major natural disasters in my country. Among them, the floods of large rivers such as the Yangtze River and the Yellow River have brought great harm to people's lives and property safety due to their wide range of influence, fast change speed, and large population along the river basins. threaten. 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, man...
