Using a 3D laser scanner to obtain point cloud data of existing buildings. High-altitude equipment can be measured with high precision in a short time without the use of scaffolding.
The construction industry is facing a serious labor shortage due to population decline and an aging society. On the other hand, there is also an increasing demand for renovation work in existing buildings from the perspectives of energy conservation, power saving, and earthquake resistance. By utilizing 3D laser scanners and point clouds for essential site surveys and current drawing creation during renovation work, it becomes possible to address the labor shortage issue, as well as shorten construction periods and reduce costs. **Advantages of Using 3D Laser Scanners** - High-precision 3D measurements can be obtained in a short time. - Measurements can be taken at heights without the use of scaffolding. - There is no risk of damage to the object being measured since measurements are taken remotely. *Note: 3D measurement refers to scanning an object to obtain point cloud data.* By importing the point cloud data obtained from 3D measurements, buildings and facilities can be recreated in 3D on a computer. Additionally, the following tasks become possible: **Utilization of Point Cloud Data** - Dimension measurement - Cross-section display - Composition of point clouds and 3D models (3D CAD) - Modeling and creation of construction drawings from point clouds (BIM compatible) **Deliverables** - Point clouds and 360° panoramic photos - 3D CAD data modeled from point clouds

Company information
At Technobrain, we use 3D laser scanners for current condition surveys of 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.
