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

Abstract

The invention discloses a watershed terrain 3D printing method and device, electronic equipment, and a storage medium. The method includes: obtaining the observation data of the river section of the target watershed and the surrounding mountain terrain data; calculating the valley points of the river respectively, based on four Second-rate Hermite The spline curve smoothes each valley point to obtain the valley line; interpolates the riverbed terrain along the direction parallel to the valley line, calculates the position and water depth of the interpolation points respectively, and obtains the riverbed terrain data; integrates the mountainous terrain data and the riverbed terrain data , standard grid resampling of riverbed topographic data to generate mountain riverbed integrated topographic data; 3D printing is carried out according to mountainous riverbed integrated topographic data to obtain a 3D model of watershed topography. The invention samples the topography of the riverbed in a direction parallel to the valley line to obtain a riverbed distribution that is closer to the real one, realizes the integrated modeling of the mountainous riverbed under the standard grid, and can express the topography distribution of the watershed 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...
