The invention provides an immovable cultural relic numerical simulation modeling method and system, and the method comprises the steps: obtaining the point cloud data of an immovable cultural relic; acquiring a surface contour line of the immovable cultural relic according to the point cloud data, and extracting coordinate points from the surface contour line to obtain a plurality of coordinate points; fitting the plurality of coordinate points to generate a plurality of surface domains; performing finite element model construction on the plurality of surface domains to obtain a finite element model; performing grid division on the finite element model to obtain a corresponding three-dimensional grid; and processing the three-dimensional grid to obtain a model simulation result. According to the method, on the basis of the point cloud data obtained in the early stage, fine adjustment is performed during modeling, fine modeling is achieved, the model is made to be close to an entity to the maximum extent, the simulation result is relatively accurate, the structure defect position can be revealed, and the performance state of the immovable cultural relic can be speculated.
Description
technical field [0001] The invention relates to the field of simulation technology, in particular to a numerical simulation modeling method and system for immovable cultural relics. Background technique [0002] The concept of protection of immovable cultural relics in my country is transitioning from rescue protection to preventive protection, and great progress has been made. As an important means of preventive protection of immovable cultural relics, many high technologies have been widely used in the daily maintenance of immovable cultural relics middle. Since the 20th century, with the development of mathematical methods and mechanical theories, computer technology has become more mature, and numerical simulation has become a possibility to solve various engineering problems such as complex media and complex boundaries. In addition, some heritage sites have a large amount of point cloud data such as 3D laser scanning, close-range photography, and total stations. How to ...
