Today’s blog post, “How Laser Scanning can be used in Construction Today,” is written by Ken Robbins, of Robbins3D.
What is Laser Scanning?
Simply put, the scanner emits a laser beam at just under 1 million times per second. The beam bounces back from the surface of the subject area to create a point in space with an X, Y and Z coordinate value. Millions of points are collected to form what is commonly referred to as a “point cloud”. The points collected are so dense that they create what appears to be a 3 dimensional picture of the area. A picture so detailed, it could be mistaken for a photograph. Multiple scanning locations can be oriented together, merging the multiple point clouds into one project point cloud. The individual clouds or the single project cloud can then be utilized to create 2 dimensional and 3 dimensional models.
