Abstract

This paper presents an instrument for 3D metrology of smooth free form work pieces. In our scheme, the integration of structured laser light and coordinate measuring systems provides high levels of accuracy, sample rate and automation of the measurement process. In order to get 3D information, a computer vision system uses the 2D projection of a non-coherent structured laser light diode on the scene. The object under inspection is placed over an indexed rotary table in order to perform multiple acquisitions in the whole measurement volume. The measurement vision system and the rotary table are calibrated by means of integrating a coordinate measuring machine into the measurement system. Experimental results are developed in order to estimate the accuracy in the 3D reconstruction.
