Embodiment 1

[0042] Please refer to figure 1 , which shows a flood three-dimensional dynamic evolution and rendering method according to an embodiment of the present invention, including the following steps:

[0043] Step S1: Obtain geographic images affected by floods at several time points, the geographic images comprising size information of geographic ranges affected by floods and terrain information associated with the geographic ranges;

[0044] Among them, the geographical image is generally a vector map, and the geographic images affected by floods can be obtained from the runoff area information on the website of the hydrometeorological station. During the rainfall process, the area where runoff is generated on the watershed is called the runoff area, and its area is called the runoff area; the runoff area of ​​the watershed changes with the rainfall process. Specifically, the watershed flow can be quantified through the deployed hydrometeorological station network observe.

Abstract

The invention discloses a flood three-dimensional dynamic evolution and rendering method, a flood three-dimensional dynamic evolution and rendering device and electronic equipment. The flood three-dimensional dynamic evolution and rendering method comprises the following steps: acquiring geographic images influenced by flood at a plurality of time points; obtaining grid data of each time point according to the geographic image of each time point influenced by the flood; according to the grid data of all the time points, utilizing a Cesium three-dimensional visualization tool to generate a dynamic grid image changing along with time; and rendering pixels in the grid image one by one through a Canva drawing tool to obtain a rendered image. According to the method, three-dimensional dynamic evolution and rendering of flood routing are carried out by utilizing a Cesium three-dimensional visualization tool and combining a Canvas drawing technology newly added to HTML5, the flood routing process can be visually, three-dimensionally and vividly expressed, and the display effect can be optimized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of flood evolution visualization, in particular to a flood three-dimensional dynamic evolution and rendering method, device and electronic equipment. Background technique [0002] Numerical simulation and visualization research on flood evolution can visualize and comprehensively understand the occurrence and development process and status of floods, as well as the submerged range and impact degree, etc., and effectively provide relevant decision-making basis for flood disaster emergency management and disaster prevention and control. Compared with the three-dimensional three-dimensional scene, the plane expression of the numerical simulation results cannot show the flood evolution scene more vividly and intuitively than the three-dimensional three-dimensional scene. The difficulty of numerical simulation of 3D visualization lies in the processing of huge data volumes of terrain and images. Many studies only...
