Abstract

Nowadays three-dimensional modelling of objects represents one of the most important topic and challenges for survey methods and technologies. Currently DSM generation of 3D objects is generally performed using laser scanning systems whose advantages, like monoscopic determination of point coordinates together with their remarkable speed, make them the preferred instruments in several applications. Nevertheless it is also possible to obtain high quality three-dimensional models using photogrammetric techniques whose difficulties are generally related to the limits of commercial software specialization, developed either for typical close-range applications or aerial photogrammetry. In the first case this software makes use of manual or semiautomatic collimation techniques on two or more images, also very convergent, but there is not the capability for automatic DSM generation. In the second case the packages are specific for 2.5D surface survey since they are generally developed for aerial photogrammetry applications. In this paper the possibility to extract 3D detailed and precise models of the hull of a sailing boat using an integration of different digital photogrammetry software is presented.
