3D Laser scanning is a process to capture any solid surface into point form. The purpose of 3D laser scanning is, to make measurement, to Create plot plan, to create 3D Model etc.
3D Laser Scanner Capture data of its surround, up to scanner's laser beam range.
Whatever is visible though our eyes, it captures everything but in 3D point form. While scanning, Scanner left intend the surface which is not visible through scanner, to capture these areas we have to take multiple scans so that full details can be captured.
