Representatives of Japan-based Pulstec Industrial Co. Ltd. held a 3D laser scanner demonstration at the CNMI Museum grounds yesterday morning, showing guests a very fast result of objects being scanned and measured.
ARCGEO Inc. Mariana Division facilitated the demonstration.
The 3D laser measurement technology, which has been adopted by Japanese automakers Toyota, Nissan and Honda, can measure the targeted object by a laser beam projection devise in a very short time. The scanner requires no contact with the object such as fragile artifacts, ruins and relics.
The 3D laser measurement system has many advantages, including the ability to produce floor plans, counter maps, elevation charts, cross-section diagrams, as well as the production of computer graphic images, replicas and virtual reality simulation.
“We hope to contribute to digital storage of cultural heritages of your country with our technology and products,” Pulstec Industrial chief technical manager Toshihisa Takai said.
The technology uses a laser projection without requiring a light source so the measurement is not affected by lighting conditions.
The presenters tried the 3D measurement system on a small marker beside the CNMI Museum yesterday and got the result within a few seconds.
ARCGEO Inc. Marianas division director Toshio Nishii said there are different sizes of the scanners for different purposes. The one they used for demonstration is the smallest model that can detect measurements of objects from one to three meters away.
The 3D scanners have the ability to measure different objects such as the amount of exhaust soil from a subway construction site, a mannequin or a human body, a sculpture, finger prints, a car, plants, ruins, a room, trees, house or buildings, sphere of stones or relics, walls, outdoors or indoors, and human bodies.
ARCGEO Inc. president Haruaki Tsushima in his message said the 3D laser measurement technology that they demonstrated yesterday is a technology that is applied to archaeological and historical sites for the first time in Japan by their company.
Tsushima said the instrument allowed them to measure a cave tomb on a cliff with higher accuracy in a short period of time than manual survey. The laser 3D scanner allowed them to detect the exact location of the sarcophagus as well as obtain a 3D measurement in the imperial mausoleum of King Eiso, a legendary king of the 13th century.
CNMI Museum executive director Robert Hunter said the 3D scanner will be useful in scanning and preserving artifacts.
“We can only give a very limited time for the researchers to get near fragile artifacts like the human skeletons, but if these artifacts can be scanned, the researchers won’t have to touch or even come near the artifacts but do their study on the scanned items,” Hunter said.
Job Market USA Corp. manager Kazunori Nakamura, who served as the translator during the demonstration, said any one who plans to construct buildings, do excavations or wants a fast and accurate measurement of objects or buildings can call them to avail of their services.
