Point cloud compression method and system based on multidimensional dynamic variable resolution

The invention relates to the technical field of point cloud data compression, in particular to a point cloud compression method and system based on multidimensional dynamic variable resolution. The method comprises the following steps: acquiring radar point cloud data, and setting an effective area of a target point cloud; analyzing the data volume and the distribution state of the radar point cloud data in the effective area; determining a method for compressing the radar point cloud data according to the data volume and the distribution state of the radar point cloud data; the invention relates to a method for dynamically compressing and storing point cloud data by using a multi-dimensional data space technology. Through the method, the overall volume of the point cloud data can be effectively reduced, and higher point cloud resolution and clearer geometric information can be dynamically stored for the hot spot area. Therefore, on the premise that the overall amount of the point cloud data is kept small, ef
