Abstract
This invention discloses a method, device, and medium for visualizing ground-based radar monitoring data. The method includes the following steps: Step S100: Back-projecting a two-dimensional polar coordinate deformation image of the radar onto a three-dimensional space based on a voxel grid; Step S200: Generating two-dimensional planar coordinate deformation data based on the deformation of the voxels; Step S300: Interpolating the filtered two-dimensional planar coordinate deformation data using a kernel density estimation algorithm to obtain a kernel density estimate; Step S400: Setting a deformation threshold and assigning colors to the voxel grid based on the deformation threshold and the kernel density estimate. The advantages are that this invention uses an improved kernel density estimation algorithm to estimate the deformation risk level (density value) of each two-dimensional planar grid, visualizes the radar deformation data on the voxel grid, and assigns layered colors to the voxels based on the density values. The voxels are easy to count and analyze, and the area of each warning level can be quickly calculated.
