摘要:In the Spring of 2003, it was realised a survey of the baptistery of Cremona (Italy) combining photogrammetric and laser scanner techniques. All the survey is composed by 22 photogrammetric images taken with a Nikon D100 18/2.8 digital camera and 14 scans collected by Optech's ILRIS-3D Laser Scanner. The geo-referencing was carried out with some natural and artificial targets displaced in the structure of the baptistery. The artificial targets used for this survey, were purposely projected, in order to get the best radiometric response and univocal geometr ical definition; instead the natural target were surveyed in a traditional topographic way with a Total Station. The solid modelling of all the monument was made using a commercial software called PolyWorks; this software allows to align different scans with different reference systems and mapping some topographic information recording that on the 3D model. This method permits to get a good architectural repr esentation (accuracy about a centimetre, calculated with some control points) and map the images onto the numerical model; thus the metr ical quality of the survey r emains unchanged without loosing the semantic settlement
