3D Laser Scanning
3D Laser scanning, also called High Definition Surveying (HDS), is a method of high-accuracy digital reality capture that uses laser beams to quickly capture complete detail of an entire building, facility, or site—much like a camera taking a 360-degree photos, but with an accurate position for every pixel. This detailed 3D representation 'as-built' of the building project is often called a ‘pointcloud'.
Why use the High Definition Surveying (HDS) method?
To avoid Outdated, inaccurate, or unavailable as-built plans and drawings that are often in hard copy 2D blueprint format. These drawings do not reflect current state of the built environment or asset condition and often times are required to make multiple site visits just to reverify measurements. Thus, due to incomplete data, there will be project delays, unforeseen problems and increased costs.
A pointcloud is a set of data points in some coordinate system. In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and often are intended to represent the external surface of an object. Point clouds are created by 3D scanners.
