This invention discloses a method for synthesizing severe weather lidar point clouds by combining real priors with geometrically guided intensity generation. First, a weather simulation module is used to convert clear weather data into pseudo-severe weather data with physical constraints from the statistical regularities of real datasets, constructing a high-quality training set. Then, using a structure-intensity decomposition diffusion model, a high-fidelity geometric structure is generated first through an asymmetric conditional diffusion process, and then matching reflection intensity information is generated based on the structure. This method effectively overcomes the modeling difficulties caused by geometry-intensity coupling in existing technologies, and achieves high-fidelity severe weather point cloud synthesis in the absence of large-scale real data.
