Splet·In PCL, several situations that need to be processed by point cloud filtering are summarized. These situations are: (1) The irregular density of point cloud data needs to be smoothed. (2) Outliers need to be removed due to problems such as occlusion. (3) A large amount of data needs to be "down-sampled" (Downsample).
