Interactive presentation method and system of GIS and BIM augmented reality in tubelane and subway construction

Abstract

The present invention discloses an interactive presentation method and system of GIS and BIM augmented reality in tubelane and subway construction. The method comprises: a GIS combines an elevation digital model with a BIM to generate a three-dimensional model, and establishes a terrain three-dimensional model on the elevation digital model, and establishes a tubelane-subway three-dimensional model on the BIM and stores the model into a database server; an imaging apparatus acquires a feature range on media, an AR client calls a terrain three-dimensional model and a tubelane-subway three-dimensional model with corresponding numbers according to the feature range to generate an overall three-dimensional model, and outputs the overall three-dimensional model into the corresponding feature range in a display device for overlapped display; and a sometosensory device acquires a corresponding gesture action of an operator, the AR client calls a terrain three-dimensional model and a tubelane-subway three-dimensional model with corresponding numbers according to the gesture action and outputs the terrain three-dimensional model and the tubelane-subway three-dimensional model into the corresponding feature range in the display device for overlapped display. The method and system disclosed by the present invention realize automatic identification and query of AR, and greatly improve working efficiency and quality.

Description

technical field [0001] The invention relates to the application fields of pipe gallery design and subway construction, in particular to an interactive demonstration method and system for GIS and BIM augmented reality in urban pipe gallery design and subway construction. Background technique [0002] Existing underground building construction includes urban pipe gallery design, subway construction and other projects, and the urban pipe gallery is designed to lay various pipes such as gas, electricity, telecommunications, water supply, rainwater, sewage and even garbage in one underground space Setup scheme for municipal plumbing in . Subway construction refers to the urban rail transit system running underground. According to the construction method, it can be divided into open-cut method, under-cut method and cover-excavation method; according to the sequence of construction, it can be divided into forward-cut method and reverse-cut method. [0003] However, the original pl...

Problems solved by technology

[0005] The purpose of the present invention is to provide a GIS and BIM augmented reality interactive demonstration method and system in the design of urban utility corridors and subway construction, so as to overcome the traditional underground construction that uses a large number of paper-based media designs and poor visibility. Failure to communicate in a timely manner will cause problems such as drawing quality and construction conflicts, which will bring great inconvenience to construction and subsequent operation and maintenance.
