3D VISION

3D acquisition through active and passive systems and measurement systems integration

Description3D Vision Lab is part of the Measurement and Experimental Techniques area, in the Mechanical Engineering Department. The main research’s fields of the group are based on non-contact measurements. The 3D Vision lab develops innovative and experimental solutions built on two and three dimension vision systems, like stereoscopy, structured light and time of flight cameras. Applicarions range from industrial to medical, but also in sports, nautical and forensic fields. The laboratory has the capacity to create their own prototypes, that generally pass trought a metrological qualification before leading possibly to an industrial product.
