Computer Vision and Reverse Engineering


The Computer Vision and Reverse Engineering laboratory is specialized in the Reverse Engineering pipeline for study, research and industrial applications: 3D devices calibration and characterization, 3D acquisition and processing, redrawing of CAD models based on 3D data. The 3D capturing equipment permits to acquire industrial components, structures, Cultural Heritage objects with a wide range of geometries, sizes and materials.

The laboratory has contributed to the production of reality-based 3D models for the following patrons:
