Point cloud data is formed based on 3D positional information acquired using LiDAR. The acquired data can be used to calculate object distances, phase differences, volume, and other information through 3D coordinates.

Advances in 3D laser scanning technology have overcome the limitations of conventional surveying and maintenance, enabling not only BIM standardization at existing construction sites but also construction management, process management, and maintenance utilizing 3D data.

Real-world, semi-permanent data serves as the foundation for structural maintenance, reverse engineering and modeling of aging structures, preservation and investigation of accident and disaster sites, and data comparison and analysis. This data serves as a key foundation for various engineering and safety management fields.
