What Is 3D Laser Scanning

A 3D Laser Scanner basically shoots a laser at the object and then captures the data in return. It does 300° by 360° scanning by rotating among it's two mutually perpendicular axes. When the scanner is setup, it literally records everything it can see and reach within the effective measuring range, e.g.,the surface of an aluminum frame, a plastered wall, the details of a door knob or switch. In simple words, WYSWYG. The scanner picks up millions and millions of points and the points are registered, so we can register the points to a survey grid. We can use the raw data, the x,y,z co-ordinates to build 3D geometric models or we can use the image captured model to do visualisations, walk-throughs and understand the actual overall picture of the site.

When we do the post-processing, we convert those x,y,z’s to true world co-ordinates. We can tell you where the point is in the real world and we can look at those point clouds in a 3D environment. We can review the model. We can spin it around. We can zoom into an area. Then we can use that information to build design models, BIM, building information models, that we can use for floor plan drawings, elevation drawings. We can cut sections thru the point cloud. We can generate traditional documents very quickly. We know the drawings are true representations of the actual space.
