Advanced crossing construction method based on combination of virtual model and real models

Abstract

The invention discloses an advanced cross construction method based on combination of virtual and real models, which comprises the following steps: a, acquiring ground feature information of a cross construction area around a main structure by adopting oblique photography of an unmanned aerial vehicle, and synthesizing a ground feature environment real scene model of the cross construction area; b, drawing a main structure BIM model according to a design drawing by adopting BIM drawing software; c, unifying coordinate systems and scales of the real scene model and the BIM model, and splicing the real scene model and the BIM model; d, performing collision detection on the spliced real scene model and the BIM model, and adjusting the BIM model according to a collision detection structure; and e, performing main structure construction according to the adjusted BIM model. By combining the BIM model and the live-action model, a unified and accurate visual medium is provided for each construction unit in cross construction for coordination and cooperation, and the method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to an advanced simulation cross-construction method combining BIM technology with a real-scene model, in particular to a method for realizing advanced simulation for cross-construction areas of multiple construction units by using a BIM model and a real-scene model. Background technique [0002] With the promotion and popularization of BIM technology, more and more construction units adopt BIM technology. Among them, collision detection is a main application scenario of BIM technology. Clash checking is a major part of eliminating changes and rework using BIM technology. The intersection of entities in engineering is defined as collision, and the distance between entities is less than the set tolerance, which affects construction or cannot meet specific requirements. It is also defined as collision. The early collision inspection brought great benefits to the project c...

Problems solved by technology

This will cause unnecessary rework or rectification, and it will be difficult to confirm the responsible unit for rework or rectification, which will lead to a situation of mutual blame and stalemate

Not only will it lead to construction stagnation and delays in the construction period, it will bring economic and reputational losses to the construction unit, and it will also cause Party A to suffer huge economic losses
