Multi-source micro-change monitoring data compounding method and storage medium

The invention relates to a multi-source micro-change monitoring data compounding method and a storage medium. The method comprises the following steps: performing compound preprocessing on multi-frame radar data; carrying out point cloud conversion processing on the rectangular coordinate system to obtain three-dimensional spherical coordinate point cloud data under a non-standard spherical coordinate system; performing point cloud reconstruction processing on the spherical coordinate system to generate a two-dimensional reconstruction image; and matching the two-dimensional reconstructed image with the radar map to complete the composition of the radar image pixel and the rectangular coordinate three-dimensional point cloud. According to the embodiments of the invention, point cloud dimension reduction reconstruction can be carried out, and the matching degree with radar map features is high. 本公开涉及多源微变监测数据复合方法及存储介质，方法包括：将多帧雷达数据复合预处理；直角坐标系点云转换处理，得到非标准球坐标系下的三维球坐标点云数据；球坐标系点云重构处理，生成二维重构图；匹配二维重构图与雷达图，完成雷达图像素与直角坐标
