3D scanning allows for a tremendous amount of information to be ascertained in a short space of time. Typically a 3D terrestrial scanner will record around 1 million measurements per second, however with recent development this number is now increasing to 2 million.
This information can then be compiled into a point cloud from which measurements can be taken. The number of measurements is so great that this technique can be described as taking the site back to the office.
A clipping plane can be used to isolate part of the scan so as to interrogate the data. The benefits to this method of surveying is that very little is left unmeasured, therefore giving a more complete understanding of the object being surveyed.
Scanning can be particularly useful for monitoring subsidence, deformation or defects within the fabric of the building.
