A new photogrammetric system for the management of cultural heritage has been conceived at the Politecnico di Torino and developed in cooperation with "Nikon Italia" and "Menci Software". The system is based on a photogrammetric station, named Stereospace, and on an "image database" named Stereophotomap. Stereophotomap could be considered as the 3D evolution of the traditional ortho-photomap. It is made of a set of aerial and/or terrestrial photogrammetric blocks and allows surveying and recording of monuments and sites, without any preliminary restitution.
Stereospace allows the user to explore the Stereophotomap and "navigate" all over the stereo-models. The user can move freely from aerial to terrestrial 3D views in a unique geo-referenced environment, and can easily measure co-ordinates of points, distances and areas.
In order to describe the system in practice the authors show how to navigate inside the Basilica of Assisi, investigate the paints and have a complete documentation of the fašade.
: image acquisition in digital form and orientation of the models are the required preliminary operations. Stereophotomap and Stereospace offer new opportunities in documentation, measuring, conservation and cultural heritage management in general.
Surveying techniques play a fundamental role in the study and knowledge of cultural goods for their cataloguing and restoration.
Traditional survey and representation methods have always had the problem of subjective interpretation of the objects.
Interpretation of the form, metrically approximate graphic representation and attention to only same physical characteristics in function of particular needs and applications has often led to partial documentation. These surveys could be used for studies and research that are different from those they were originally planned for.
A new photogrammetric system for the management of cultural heritage has been conceived at the Politecnico di Torino and developed jointly with Nikon Instruments S.p.A and Menci Software S.r.l.. The system is based on a photogrammetric station, named Stereospace, and on an "image database" named Stereophotomap.
Stereophotomap and Stereospace allow one to read the space and the objects without any subjective interpretation. They give a complete knowledge of space and complex shapes. The users can move around the objects, study the context and measure each part using traditional photogrammetric procedures and new digital image processing techniques.
An example of Stereophotomap of the Basilica of Assisi has been carried out that is consultable with Stereospace.
