The performances of 2D digital imaging systems depend on several factors related with both optical and electronic processing. These concepts originated standards, conceived for photographic equipment and bi-dimensional scanning systems, for calculating different system parameters such as resolution, noise or dynamic range. On the other hand no standard test protocols currently exist for evaluating the performances of 3D imaging systems such as laser scanners or pattern projection range cameras. This paper is focused on investigating an experimental process that allows to evaluate some critical parameters of a 3D equipment, extending concepts defined by the ISO standards to the 3D domain. In particular it is focused on experimental estimation of resolution along the three axes, for seven different 3D range cameras, based on both laser scanning and pattern projection. The general aim of this contribution is to suggest an easy characterization process for generating a reliable comparison between 3D scanner performances.

Abstract
The performances of 2D digital imaging systems depend on several factors related with both optical and electronic processing. These concepts originated standards, conceived for photographic equipment and bi-dimensional scanning systems, for calculating different system parameters such as resolution, noise or dynamic range. On the other hand no standard test protocols currently exist for evaluating the performances of 3D imaging systems such as laser scanners or pattern projection range cameras. This paper is focused on investigating an experimental process that allows to evaluate some critical parameters of a 3D equipment, extending concepts defined by the ISO standards to the 3D domain. In particular it is focused on experimental estimation of resolution along the three axes, for seven different 3D range cameras, based on both laser scanning and pattern projection. The general aim of this contribution is to suggest an easy characterization process for generating a reliable comparison between 3D scanner performances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
