Abstract
The results of the activity carried out to verify the measurement performance of an optical three-dimensional sensor based on the projection of structured light are presented in this paper. The followed approach is the substitution approach, in which repeated measurements are carried on a calibrated object. These measurements have been accomplished by using a Coordinate Measuring Machine. The work carried out allows us to appreciate the performance of the optical system as well as to outline the critical aspects. These are mainly related to the quality of the master used for the calibration of the sensor, and to the efficiency of the alignment algorithm, whenever multi-view acquisition is required.Pubblicazioni consigliate
