Problems solved by technology

[0002] The application of BIM technology in the construction field of the construction industry has gradually become mature and clear, mainly reflected in the detailed design and collision inspection. However, due to certain errors between the physical construction and the BIM model, it is impossible to associate the site with the BIM model in real time. The established models are all idealized, and the entire site cannot be fully controlled. There are the following disadvantages:
[0007] Traditional construction surveys

Abstract

The invention discloses a field construction management system combining 3D laser scanning technology and BIM technology, includes establishing and optimizing BIM model and managing construction quality on site. the process includes the following steps: (1) data collection: using a 3D laser scanner to scan on site, collecting the real and complete original data of target structure project, and obtaining the point cloud data with accurate spatial information; B, data processing: splicing, denoising, classifying and coloring the collected three-dimensional laser point cloud data by using the point cloud data preprocessing software; C, establishing a scanning model: importing that preprocess point cloud data into the Revit software to generate a scanning BIM model; D, 3D laser scanning and BIM technology synchronous site construction management: the scanned BIM model being accurately compared with the design CAD model and the BIM model, the difference between the construction site and thedesign being found, and the design model being optimized; simplifying the workload of quality management personnel.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an on-site construction management system combining 3D laser scanning technology and BIM technology. Background technique [0002] The application of BIM technology in the construction field of the construction industry has gradually become mature and clear, mainly reflected in the detailed design and collision inspection. However, due to certain errors between the physical construction and the BIM model, it is impossible to associate the site with the BIM model in real time. The established models are all idealized, and the entire site cannot be fully controlled. There are the following disadvantages: [0003] Traditional modeling has a large workload, low modeling efficiency, multi-discipline crossover, and poor integration of sub-specialty modeling. Therefore, the comprehensive ability of modelers is required to be high. [0004] Traditional BIM applications are mainly us...
