(Building Information Modeling) BIM based plan graph and first view-angle split-screen synchronous display method and system

Abstract

The invention provides a BIM based plan graph and first view-angle split-screen synchronous display method and system. The method comprises loading and displaying a BIM stereo model; matching a navigation norm with a model bearing; generating a corresponding plane graph and placing a virtual camera; generating a corresponding first-person view-angle graph according to the camera position and view-angle information; displaying the view-angle bearing through the navigation norm visually, and providing a compass function; adjusting the view angle of the first-person view-angle graph according to user instructions, an adjusting the projection view angle direction of the virtual camera in the plane graph according to current view-angle data; and using the plane graph and the virtual camera projection as one portion and the first-person view-angle graph as the other portion to be displayed synchronously in a same screen. By means of the method and the system, a plane drawing and the first-person view-angle stereo graph are combined, the model bearing and the compass are combined, and accordingly, detail members can be observed and searched visually, the site actual engineering member and model member matching problem can be determined visually, construction management is facilitated, the requirement for the personnel technology is reduced, and even general workers can observe, record and search for the detail members according to images displayed on the same screen.

Description

technical field [0001] The invention relates to BIM application technology and IT fields, and is used in intelligent engineering management, in particular to a technology and method for displaying BIM models on a mobile client. Background technique [0002] BIM is Building Information Modeling (Building Information Modeling), as a complete information carrier of construction projects, it is an innovative method of architectural design, construction and management. Its main feature is that it can continuously and instantly provide high-quality, consistent and reliable project design scale, progress and cost information. Architects, structural engineers and the whole process management of engineering projects realize seamless connection and share data and information through the BIM collaborative platform. Use BIM technology to improve refined management and reduce resource consumption and energy consumption. BIM has become an important technical means for the whole process ...

Problems solved by technology

However, there are some obvious defects in Revit: 1. The requirements for hardware equipment and technical personnel are very high, resulting in high cost of facilities and personnel; 2. The model in Revit cannot be well combined with the on-site construction management. ;3. It is limited to PC client only, and cannot be viewed on mobile terminals (tablets, mobile phones, etc.)

However, there are still some defects: 1. More monitoring for progress and safety, unable to effectively manage problems on the construction site; It is equipped with a computer and requires a lot of equipment to support the entire system, which is expensive

However, it has some defects: 1. It can only transmit data and 2D pictures instead of an intuitive 3D three-dimensional model, and cannot manage and operate the project site conveniently and intuitively; 2. For personnel in different professional positions, specific data needs to be selected for interactive, relatively inefficient
