Laser scanning is a technology that uses laser beams to capture precise measurements of objects and environments. It works by emitting laser pulses and measuring the time it takes for the light to bounce back. This data is then used to create detailed 3D models of the scanned area or object. The resulting 3D models can be used in various fields, including architecture, engineering, and heritage preservation. Laser scanning provides high accuracy and efficiency, making it a valuable tool for documenting existing conditions, planning renovations, or analyzing structures.
