ABSTRACT

The x y z coordinates relate the points, measured on real world objects, to the origin of the scanner, or more often to a project coordinate system used to tie several scans together. The ability of a laser scanner to capture large amounts of data quickly and with a fine resolution means that the real world can be accurately modelled. [Bornaz et al 2004]

The results of this research show that the terrestrial laser scanning technique gives an accurate and a reasonable method for measuring the bowing of marble panels and the delamination of brick building facades, which could be also used for measuring the bowing and defects of the concrete elements of building facades.
