Flatness controls
Flatness control, which involves the quantification of deviations between an existing surface and a notional model, is a field where laser scanning is indispensable.
The conventional technique, described as the "2 metre rule" is not always appropriate to the flatness control of large plane surfaces, such as sports halls, concrete foundation slabs or façade walls.
The processing of clouds of points generated by 3D laser scanning will allow the comprehensive comparison of actual conditions with notional plans, revealing variations with an unparalleled degree of accuracy and ease of reading (colour maps of deviations, profiles, etc.).
The end product is a genuine decision-making resource for checks, analyses and inspections.
