Reverse Engineering is a rapidly evolving discipline. Nowadays shape acquisition systems
have reached enough capabilities to reproduce complex free form objects. This paper presents a
comparison between two different acquisition systems to evaluate their performances and their easy to use
capabilities and to evaluate quality and accuracy of the 3D reconstructed models. To achieve this task, a
complex free form object, a steam turbine blade, was acquired. After shape acquisition and data
elaboration of this particular object an evaluation of the two systems characteristics and of the 3D CAD
reconstructed models were done and results are illustrated here
