It is possible to measure from a distance without the risk of damage to the object due to contact, allowing for high-precision measurements in a short time.
【Example】 Location: Fukuoka Castle Ruins Area: Approximately 700 square meters Number of Measurements: 35 locations Measurement Time: Approximately 3 hours and 30 minutes Measurement Data Confirmation: Approximately 1 hour (Total: Approximately 4 hours and 30 minutes) 【Measurement Conditions】 ■ Measurements can be conducted outdoors and indoors ■ Due to equipment specifications, the ideal temperature during measurements is between 5°C and 40°C ■ Measurements can be taken at night or in dark places, but obtaining color information is difficult ■ Outdoor measurements may be impossible depending on weather conditions due to laser reflection and refraction from rain or fog ■ Glossy surfaces that reflect lasers or black objects that absorb lasers will reduce point cloud acquisition rates ※ Mirrors and glass typically cannot obtain point clouds ■ Moving objects during measurement will be processed as noise during data processing ※ For accuracy in point cloud acquisition, it is preferable to measure during times when there are no people present ■ Generally, measurements are taken from below, so point clouds of the top surfaces of objects cannot be obtained. If point cloud acquisition is necessary, measurements should be taken from a height 【Examples of Point Cloud Data Utilization】 ■ Dimension measurement ■ Cross-section display ■ Height display ■ Intensity display ■ 3D modeling ■ VR, etc.

Company information
At Technobrain, we use 3D laser scanners to conduct current condition surveys for renovation work and modeling from point clouds. Leveraging the technology of "3D laser scanning measurement" developed on-site, we are also engaged in the digital preservation of cultural properties. "4K + 3D shooting" is a technology that creates high-quality 3D spaces that can be viewed anytime and anywhere by capturing the entire surrounding area. It allows for free movement within a realistic space composed of 4K photographs, and VR experiences are also possible. This technology can be utilized in a wide range of fields, including current condition surveys of construction sites, promotion of cultural properties, accommodation facilities, commercial facilities, and real estate property introductions. Additionally, we create BIM-compatible construction drawings and develop VR, AR, and MR content from CAD data.
