Construction site virtual construction restoration method based on BIM + GIS

Abstract

The invention provides a construction site virtual construction restoration method based on BIM + GIS, and the method comprises the steps of collecting the topographic data of a project site, and forming a database; processing the data in the database to generate a GIS model; extracting coordinates and elevation information of the three-dimensional oblique photography data and the three-dimensional forward photography data through a Global Mapper, so a forward photography map is synthesized; combining the construction site three-dimensional model and the forward photography model, and positioning coordinates, sizes and forms of objects needing to be protected on the construction site or needing to be restored after a project is completed to serve as model data backup; positioning coordinates, sizes and forms of objects needing to be protected on a construction site or needing to be restored after a project is completed, and providing data help for follow-up reinforcement, protection and restoration scheme making and work. By utilizing the characteristics of high precision, visualization, high efficiency and the like of the BIM + GIS technology, a construction total plane arrangement diagram is deeply designed, and a project construction site is assisted to realize green construction.

Description

technical field [0001] The invention relates to a virtual construction restoration method of a construction site based on BIM+GIS. Background technique [0002] Whether the layout of the construction site is scientific and reasonable directly affects the production efficiency. In the early stage of the project, it is necessary to plan and implement the space and layout of the construction site. It is often necessary to simulate the layout in combination with the topography and topography of the site, surrounding existing buildings, proposed buildings, construction process period, and the location and elevation of temporary facilities. Cloth, plan and then move. [0003] At present, BIM (Building Information Modeling) is not only a new tool for architectural design, but also a new tool for building construction, operation and maintenance. The core of it is the model as the carrier, using digital technology to display all kinds of physical data and actual information of arch...

AI Technical Summary

Problems solved by technology

[0006] Existing construction site layout technology only relies on construction experience and specifications for planning and design on CAD drawings. The effect cannot be reflected intuitively, and it is prone to waste land and dead ends, as well as the secondary handling caused by different construction stages (periods) and the demolition and reconstruction of processing plants and warehouse yards, resulting in waste of resources; The backup materials of the objects that need to be restored after protection or project completion are inaccurate, which makes the protection or restoration quite different from the original state, which is not conducive to monitoring
