KICT develops scan to BIM for reverse engineering from 3D vision data

Newly developed cost-effective technology

2023-10-23

(Press-News.org) Korea Institute of Civil Engineering and Building Technology (KICT, President Kim Byung-suk) has developed building scan to BIM (Building Information Modeling)-based reverse engineering technology required for 3D geospatial information modeling domains such as digital twin information modeling.

Scan to BIM-based reverse engineering technology was studied to prevent errors and rework caused by manual work when modeling shapes or BIM from 3D scan data. Existing reverse engineering work is either done based on a lot of manual work or semi-automatically using expensive overseas software.

KICT Research Fellow Dr. Kang Tae-wook and the international joint research team (University of North Florida, Prof Jonghoon Kim., Purdue University, Prof Kyubyung Kang., IUPUI, Prof Dan Koo., The State University of New York, Prof Jongseong Brad Choi) developed Scan to BIM technology customized for each reverse engineering purpose based on accumulated 3D vision, deep learning, and data processing pipeline technologies.

This technology automatically segments objects from 3D point cloud data, extracts shape information, and creates BIM objects. Through this, information model creation time and rework required for digital twins can be dramatically reduced. In this regard, productivity analysis cases were presented through SCIE paper (Kang, 2023, Scan to BIM Mapping Process Description for Building Representation in 3D GIS, Applied Sciences). According to published data, this technology improves reverse engineering productivity by 23.7 times and improves the amount of modeling information by 110.21%. Additionally, this technology can be customized depending on the purpose.

This technology is used for 3D precision map construction, 3D vectorizing, abnormal pattern detection during construction site safety management, precise construction management, and 3D digitalization of spatial information using the location, size, and direction information of objects required from scanned image data, etc. It can be used as a base technology that can be used in vision-based robotics and autonomous driving support systems.

The developed technology is being tested on-site with a scan reverse engineering company (BNG Co., Ltd) collaborating with Trimble Building Point in Korea and overseas partner organizations. In addition, for the development of the industry, some technologies were open-sourced and shared on GitHub (github.com/mac999/scan_to_bim_pipeline).

Dr. Kang said, "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." "The recently developed Scan to BIM technology will greatly help AEC domestic industrial competitiveness," he added.

Crystals brought back by astronauts show that the Moon is 40 million years older than scientists thought

2023-10-23

More than 4 billion years ago, when the Solar System was still young and the Earth was still growing, a giant object the size of Mars crashed into the Earth. The biggest piece that broke off of the early Earth formed our Moon. But precisely when this happened has remained a mystery. In a new study in the journal Geochemical Perspectives Letters, researchers used crystals brought back from the Moon by Apollo astronauts in 1972 to help pinpoint the time of the Moon’s formation. Their discovery pushes back the age of the Moon by 40 million years, to at least 4.46 billion years old. “These ...

Probiotics delivered in biofilm state protect the intestines and brain in NEC model

2023-10-23

(COLUMBUS, Ohio) – Necrotizing enterocolitis (NEC) is a debilitating and deadly condition that affects infants who were born preterm. In NEC cases, intestinal tissues become inflamed, and in severe cases there is ischemia and death of the involved intestines. Treatment for NEC often involves surgery to remove the dying tissue. “Even after decades of research, little has changed in terms of prognosis for infants who develop NEC,” says Gail Besner, MD, pediatric surgeon and principal investigator in the Center for Perinatal Research at Nationwide Children’s. ...

Heated yoga may reduce depression symptoms, according to recent clinical trial

2023-10-23

BOSTON – In a randomized controlled clinical trial of adults with moderate-to-severe depression, those who participated in heated yoga sessions experienced significantly greater reductions in depressive symptoms compared with a control group. The results of the trial, which was led by investigators at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), and was published in the Journal of Clinical Psychiatry, indicate that heated yoga could be a viable treatment option for patients with depression. In the eight-week trial, 80 participants ...

Finding Argoland: how a lost continent resurfaced

2023-10-23

Geologists have long known that around 155 million years ago, a 5000 km long piece of continent broke off western Australia and drifted away. They can see that by the ‘void’ it left behind: a basin hidden deep below the ocean known as the Argo Abyssal Plain. The underwater feature also lends its name to the newly formed continent: Argoland. The structure of the seafloor shows that this continent must have drifted off to the northwest, and must have ended up where the islands of Southeast Asia are located today. ...

Does diabetes affect the survival of individuals with colorectal cancer?

2023-10-23

Complications of diabetes can have numerous negative health effects, from impaired vision and nerve damage to kidney dysfunction and heart disease. In an analysis of information on adults with colorectal cancer, patients who also had diabetes—particularly those with diabetic complications—faced a higher risk of dying early. The results are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. For the study, Kuo‐Liong Chien, MD, PhD, of National Taiwan University, and his colleagues ...

Better regulation of mental health ‘therapies’ urgently needed to protect the vulnerable

2023-10-23

A rise in psychological pseudoscience is putting people at risk, psychologists have warned, with social media and celebrity endorsements partly to blame. Mental health apps, mood-boosting supplements and energy therapies are among the therapies that could do ‘more harm than good’ according to psychologists Jonathan Stea and Stephen Hupp in their new book Investigating Clinical Psychology. “As discourse around wellness, mental health, therapy, and access to these resources increasingly enter the public domain, the potential of coming across persuasive pseudoscience has also increased,” Stea explains. “This is the age of health misinformation. It is everywhere. ...

Do people everywhere care less about their cats than their dogs?

2023-10-23

Do canines get more care? Some studies have suggested pet owners are less emotionally attached to and less willing to finance care for cats than dogs, possibly because of cats’ behavior: cats may be perceived as caring less about humans and needing less care in return. But these studies are often conducted on non-representative samples and don’t consider possible cultural differences in attitudes to pets. A team of scientists led by Dr Peter Sandøe of the University of Copenhagen decided to investigate further. “We and others have found that people are willing to spend much less on their cats than ...
