The Laboratory has been working on 3D Vision systems and techniques since 1990, resulting in a vast list of publications and start-ups on the subject. The main topics include inspection, measurments, 3D reconstruction and modelling, with a smart use of rapid prototyping techniques to recreate objects and reverse engineering techniques.

One of the activities carried out at the lab over the years has been to use 3D range cameras to perform the reverse engineering of free form shapes, in view of establishing a method for the achievement of topological informations of the shapes in the form of meshes. The transversal nature of the process has led to apply it to a large field of applications, such as cultural heritage, industry and medicine.
