Construction progress visualization method based on BIM model and monitoring image comparison

Abstract

The invention discloses a construction progress visualization method based on BIM model and monitoring image comparison, and belongs to the technical field of calculation, reckoning or counting. The method comprises the following steps of building a BIM model with precision and granularity meeting construction progress management requirements, and giving recognizable unique codes to the BIM model; hooking construction plan data to the built BIM model; acquiring image data shot by construction monitoring equipment, and identifying a structure under construction and a constructed structure of a construction area; automatically analyzing an identification result and the plan progress, and reflecting the progress state and the progress deviation through different colors of the BIM model. Under the background that more and more engineering projects apply the BIM model and the monitoring equipment, the application path of the BIM model and the monitoring equipment in construction is expanded, and an informatization scheme with excellent intuition and good integrity is provided for construction progress management.

Description

technical field [0001] The present invention relates to BIM (Building Information Modeling, Building Information Modeling) technology and image recognition technology, in particular to a construction progress visualization method based on the comparison between BIM models and monitoring images, which belongs to the technical field of calculation, calculation or counting. Background technique [0002] Engineering construction projects are characterized by large size, complexity, long period, and many related units. The paper "Research on Influencing Factors of Construction Project Delay Based on Principal Component Analysis" (Peng Yushi, Chongqing University, 2014.) demonstrates that progress, cost, and quality are The three leading goals of a construction project, and emphasize the important position of the progress goal, and a careful and reasonable progress plan is a detailed operation guide for the realization of the progress goal. Therefore, for an actual engineering pro...

[0003] However, as stated in the article "Safety Risk Identification System for the Full Life Cycle of Integrated Pipe Gallery" (Qiang Wanming, Shang Dongfan, Lu Ming, Journal of Civil Engineering and Management, 2019, 36(05): 40-44.) The traditional schedule management method is usually formulated based on the WBS (Work Breakdown Structure) method, that is, the project elements are grouped according to the deliverables. The limitations of this traditional project schedule management method are: (1 ) The granularity of project division is rough, the schedule plan is not intuitive enough, and it is difficult for project managers to grasp the details of the plan, which may easily lead to unreasonable resource allocation; (2) For a large-scale project with complex professional composition, delays in the construction process are not easy to be discovered and resolved in time Adjustment may cause the progress to be delayed again and again; (3) The relationship between progress management and cost and resource management is not close enough, and the construction period and cost are often not optimized

The introduction of BIM technology into construction progress management is an important means to achieve this goal. The specific implementation method has been explored partly. The application number is CN2015109151730. The invention name is "construction progress management method based on visualization technology" and the application number For CN2016107881004 patent titled "Railway Subgrade Construction Progress Management System and Management Method Based on 3DGIS and Engineering 3D Model", the construction progress management system was developed by using the information management capability of BIM model, but the connection between BIM model and data completely depends on Manually, there is a huge workload defect in engineering projects with large volume and complex structure

The Chinese patent with the application number CN2017100172641 and the invention title "A BIM-IFC Technology-Based Building Construction Progress Management Platform and Method" proposes to compare the measured data with the planned data by using laser equipment, but additional equipment is required to convert the planned data After converting to the IFC standard format file and comparing it with the measured progress data, the advantages of BIM visualization attributes are not fully utilized, and the comparison results between the planned data and the measured data cannot be visually displayed in the BIM model
