3D laser scanning and LiDAR are two terms often used interchangeably. 3D laser scanning creates a 3D model of an object or environment using a laser beam. Light Detection And Ranging (LiDAR), on the other hand, is a remote sensing technology that uses lasers to measure the distance to an object.
While both technologies can be used to create 3D models, they are different processes. A LiDAR 3D scanner is a 3D scanning device based on LiDAR technology that can digitise the three-dimensional coordinates of a physical object and display them digitally as point clouds on a computer.
