Summary:The invention relates to the field of electric power automation, in particular to a three-dimensional grid-based automatic point cloud classification method in a substation scene. The method comprises the following steps: de-noising three-dimensional point cloud data polled by an unmanned aerial vehicle, performing downsampling to divide grids, and performing coarse classification on the grids by using spatial features of a power line and an electric power tower; correcting and complementing the power line by using the spatial line characteristics of the power line; correcting the category of an electric power tower and calculating the center of the electric power tower by utilizing the spatial relationship between the electric power tower and a power line, performing clustering segmentation by taking the center as a seed point, and then performing up-sampling to obtain accurate point cloud classification of the electric power tower and the power line. The classification method can establish an accurate spati
