The Korea Institute of Civil Engineering and Building Technology (KICT) has created a scan to BIM-based reverse engineering technology
The scan to BIM technology can be used for 3D geospatial information modelling, such as digital twin modelling.
The invention eliminates errors and manual rework when transforming 3D scan data into BIM or shape models, traditionally done manually or with expensive overseas software.
Dr Kang Tae-wook and an international research team developed a customised solution using 3D vision, deep learning, and data processing technologies. The team included researchers from the University of North Florida, Purdue University, and the State University of New York.
The discovery was made during a research project titled, ‘3D vision & AI based Indoor object Scan to BIM pipeline for building facility management’.
How does the scan to BIM technology work?
This technology automatically segments objects from 3D point cloud data, extracts shape information, and generates BIM objects, significantly reducing modelling time and rework for digital twins.
According to the KICT researchers, the technology can lead to a 23.7 times improvement in productivity and a 110.21% increase in modelling information. The technology can be tailored to specific needs.
The technology has applications in 3D map creation, vectorisation, construction site safety, precise construction management, and spatial data digitisation, making it versatile for vision-based robotics and autonomous driving support systems.
The technology will undergo testing
Collaborations with companies like BNG Co., Ltd and Trimble Building Point are underway for on-site testing, and some technologies have been open-sourced on GitHub to boost industry development.
“Currently, scan to BIM reverse engineering automation technology is difficult to specialize for each purpose in construction, and the cost for the AEC (Architecture, Engineering, and Construction) industry to utilize the technology is also high,” said Dr Kang.
“The recently developed Scan to BIM technology will greatly help AEC domestic industrial competitiveness,” he concluded.
