Application of the Triangulated Irregular Network (TIN) Method in the Creation of Models of Historical Buildings

Abstract

Renovation or modernization of a historical building involves creating its model. An accurate 3D representation of a building can be used e.g. to analyse the possibilities of renovating or recovering its damaged elements. This paper discusses examples of how helpful 3D laser scanning can be in creating models of historical buildings. This technology is of particular importance when it comes to representing decorative architectural details. To create a 3D image of a building using reverse engineering one must first gather on-site data by means of terrestrial laser scanning in the form of a point cloud. This paper describes the process of creating a model of a historical building by means of the TIN method using Leica’s Cyclone programme. The on-site measurements were taken using a ScanStation C10 scanner, also by Leica.
