3D laser scanning, or LiDAR (Light Detection and Ranging), is a technology that uses laser beams to rapidly capture highly accurate three-dimensional data of objects, structures, or landscapes. It measures distances by calculating the time it takes for laser pulses to bounce back from surfaces. This data is used in various applications, including architectural and engineering design, land surveying, environmental monitoring, and archaeology. 3D laser scanning enables precise and detailed 3D modeling, enhancing efficiency and accuracy in a wide range of industries.
