[0006] 2. Subsequent impact: it may affect the subsequent secondary structure, installation engineering, steel structure, curtain wall structure and decoration engineering, etc., resulting in a series of unpredictable impacts
[0007] At the same time, when using the existing measurement methods to control the structural deviation, it takes a lot of labor because of the need for actual measurement and measurement, and because of the three-dimensional properties of the component itself, for the spatial coordinates of a single component, it is necessary to pass through multiple angles. It is difficult to realize the measurement, and it is difficult to express, so it is difficult to refine the error control of the component

Abstract

The invention discloses a steel structure non-contact actual measurement method and system based on a three-dimensional scanning technology, and the method comprises the steps: timely discovering theaccumulated deviation in a construction process through the three-dimensional scanning technology, carrying out the output through a BIM model, and carrying out the installation adjustment in time, soas to minimize an error. According to the method, the method comprises the steps of establishing a construction drawing BIM model to reflect design structure size information on a construction drawing; scanning the field construction area in real time by using a 3D scanner to obtain field actual size data; comparing the BIM model with the 3D scanner data; and judging the structural size deviationthrough three colors of green (qualified), yellow (warning) and red (unqualified).

Description

technical field [0001] The present invention relates to the technology of engineering measurement control based on BIM technology, specifically relates to the application of engineering measurement and actual measurement based on BIM technology combined with three-dimensional scanning technology, and is mainly applied to the method and system of main structure deviation control. Background technique [0002] BIM technology is the abbreviation of Building Information Modeling (Building Information Modeling), and its purpose is to help realize the integration of building information, so that all staff can work together, effectively improve work efficiency, save resources, and achieve sustainable development. In many application scenarios, BIM is an important carrier for feedback information and ultimately guiding on-site construction. [0003] Three-dimensional scanning technology refers to the technology of scanning the spatial shape, structure and color of objects to obtain ...
