In this paper the main results from the industrial comparison "VideoAUDIT" are presented and discussed. The comparison, designed and coordinated by the Laboratory of Industrial and Geometrical Metrology of the University of Padova, involved 21 optical CMMs from various companies in Europe (Italy, Switzerland, Spain and Denmark). The comparison was run between August 2007 and January 2009. The participants were given the opportunity to verify the metrological performances of their CMMs with suited artefacts and procedures. Based on the comparison results, the actual quality of industrial optical measurements was evaluated.
