Resumen de A Reverse Engineering Methodology to Capture Complex Shapes
Sandro Barone, Armando Viviano Razionale
This paper presents a research activity concerning the development of a non-contact scanning system based on combining structured light with stereo vision. A methodology is proposed to establish reliable dense correspondences among a pair of cameras on the basis of vertical and horizontal coded fringe patterns. The methodology can efficiently be used to measure free-form shapes, which typically do not present peculiarities usable by classical correlation procedures.The proposed technique is the core of a complete 3D shape measurement framework, which also includes a multi-scan procedure to reconstruct complex surfaces. In this work, the system has been successfully used to measure styling surfaces of sport cars. Inparticular, the methodology has been applied to acquire and model the shapes of a scaled vehicle prototype, typically, used for aerodynamic tests in wind tunnel
