Palermo off ers a repertoire of both artistic
and architectural solid perspective of great beauty and
in large quantity. This paper addresses the problem of
the 3D survey of these works and their related study
through the use of image-based modelling (IBM) techniques.
We propose, as case studies, the use of IBM
techniques inside the Cathedral of Palermo. Indeed, the
church houses a huge and rich sculptural repertoire, dating
back to 16th century, which constitutes a valid field
of IBM techniques application.
The aim of this study is to demonstrate the e ffectiveness
and potentiality of these techniques for geometric
analysis of sculptured works. Indeed, usually the survey
of these artworks is very diffi cult due the geometric complexity,
typical of sculptured elements. In this study,
we analysed cylindrical and planar geometries as well as
carrying out an application of perspective return.peer-reviewe
