Abstract
Viene descritto un sistema basato sull'abbinamento di una telecamera (10) ad una macchina di misura (5) in modo da fornire una completa libertà di posizionamento della telecamera all'interno del volume di misura della macchina, sostituendo la presa di punti manuale e la definizione delle traiettorie dei sistemi di misura tradizionali, utilizzanti palpatori, con una semplice inquadratura della porzione di superficie da misurare, dotata di linee a forte contrasto rispetto alla superficie stessa. Il sistema comprende un elaboratore di immagini (16) che controlla l'acquisizione di due differenti immagini della superficie, per localizzare le linee a forte contrasto. Un elaboratore stereo (17) provvede quindi a correlare fra loro i punti delle due immagini, a calcolare le coordinale tridimensionali di lati punti e le equazioni delle curve e delle superfici passanti per tali punti.Figura 2.
