Point cloud rasterizing method and device based on gridding multi-neighborhood interpolation

The invention provides a point cloud rasterizing method and device based on gridding multi-neighborhood interpolation, and relates to the technical field of point cloud data processing, and the method comprises the steps: carrying out the rasterizing of all point cloud data, and obtaining a grid image; performing gridding processing on the grid image to obtain a gridded grid image, and obtaining and storing the number of point clouds and the serial number of the point clouds of each grid in the gridded grid image; for each pixel of the grid image, acquiring a grid to which the pixel belongs; obtaining the elevation value of each pixel through interpolation processing by using the number of point clouds in the belonging grid and the surrounding grids and the elevation values; and taking the elevation value of each pixel as a pixel value to obtain a point cloud grid image. According to the invention, the processing speed and precision of point cloud rasterization are improved. 本申请提供了一种基于网格化多邻域插值的点云栅格化方法及装置，涉及点云
