Flood three-dimensional dynamic evolution and rendering method and device and electronic equipment

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, th
