The invention relates to the technical field of civil engineering and municipal engineering, and discloses an automatic construction method for a space convergence structure based on an interpolation algorithm, which mainly comprises the following steps of: automatically extracting elevation control points and elevation information in a design drawing through a programming platform, and performing data matching on point locations on the surface of the convergence structure; improving elevation control point precision based on a spatial interpolation algorithm, creating a point position set, fitting a curved surface shape of a spatial convergence structure surface through the point set, then extending and thickening the curved surface downwards, constructing a spatial convergence structure model body, outputting a model to a design platform, and mounting attribute information. The method is operated on a programming platform, computer programming statements are utilized, encryption and data matching of elevation control points are achieved, and a space convergence structure entity is automatically generated. According to the method, the design precision of the space convergence structure can be well improved, meanwhile, the attribute management information is mounted in the space convergence structure model, the engineering information management efficiency is effectively improved, and the construction quality is controlled.
Description
technical field [0001] The invention relates to the technical field of civil engineering and municipal engineering, in particular to a method based on BIM technology, which uses an interpolation algorithm to encrypt the elevation control points of the spatial intersection structure, and realizes the automatic construction of the spatial intersection structure. Background technique [0002] Building Information Modeling (Building Information Modeling) is based on the relevant information data of the construction project as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation.
