Abstract

The embodiment of the invention provides a BIM model and GIS model registration method, and the method comprises the steps: respectively extracting the feature points of a BIM model and a GIS model, carrying out the rough matching of the feature points of the BIM model and the feature points of the GIS model to obatin a point pair after rough matching; performing accurate matching on the point pairs after rough matching, and establishing a one-to-one correspondence point pair relationship between the feature points of the BIM model and the feature points of the GIS model; and based on the one-to-one correspondence point pair relationship, performing spatial registration on the BIM model and the GIS model, and solving registration attitude parameters. According to the embodiment of the invention, the BIM model and the GIS model are automatically and accurately matched, and the attitude registration parameters of the BIM model and the GIS model are solved, so that the BIM model is coordinated with the scene position and orientation of the original GIS model and does not conflict with the original GIS model after being arranged, the efficiency is ensured, the manual intervention intensity is reduced, and the automation degree is improved.

Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to a registration method for a BIM model and a GIS model. Background technique [0002] BIM (Building Information Modeling, Building Information Modeling) model is a building or building engineering information model that is composed of sufficient information to support new product development management and can be directly interpreted by computer applications, that is, life cycle management of the building environment supported by digital technology . The core of the BIM model is to establish a virtual three-dimensional model of construction engineering and use digital technology to provide a complete and consistent construction engineering information library for this model. The information base not only contains geometric information, professional attributes and state information describing building components, but also contains state information of no...
