Geometric Tolerance Verification - Innovative Evaluation of Facade Surface Flatness Using TLS (Terrestrial Laser Scanning)

Article Preview

Abstract:

This article assesses the application of TLS when evaluating the façade surface flatness on finished facade. Current methods of geometrical tolerance verification are reviewed and the results are compared data obtained from point clouds (using TLS).The process of currently used methods consist of manual verification of flatness by spirit level in accordance with national standards, which specifies exact places to be assessed and the number of measurements. With TLS technology we assess the surface quality and flatness more precisely, faster and moreover, investigate 100% of area. This may lead to better evaluation of the relative position of investigated areas, points and constructions. However, a further investigation, which would define the methodology for evaluation the geometric tolerance from point clouds is needed.
