A 3D Laser Scanner operates by emitting a laser beam, which interacts with objects, bouncing back to the scanner’s sensor. The scanner’s onboard computer then performs calculations to pinpoint the exact location in space from which the return originated. For each return, it generates X, Y, and Z coordinates relative to the scanner’s centre. Remarkably, some advanced scanners can accomplish this process at speeds of up to 1,000,000 times per second. The outcome of this rapid scanning procedure is the creation of a Point Cloud, a digital representation consisting of countless precise 3D coordinates in space.
