A scan can be used to generate F-numbers but provides a more comprehensive analysis in the form of a heat map.
A heat map can be superimposed onto the point cloud. Note that even the people were scanned.
Individual scans locations are spaced to provide complete coverage of the floor surface.
This Faro laser scan reveals a near identical floor profile (and F-numbers) as a total station or a Dipstick.
Scanning wet, when surface quality can be addressed, could be an important use of 3D laser scan data.
