• The primary data model of the current point cloud is still the organization of discrete points. Point clouds and patterns areindependent of each other. Firstly, this paper establishes the data structure of multi-layer integrated ancient buildingsbased on the point cloud model. The purpose is to adapt to ancient buildings' laser point cloud processing technology.Then this paper uses Lagrangian mathematics to model the point cloud pattern. Finally, the paper verifies that thecartographic model of ancient buildings established by the Lagrangian formula is smooth and accurate. The model canexpress detailed information about ancient buildings
