Resolution analysis represents a 2D imaging topic for the use of particular targets for equipment characterization. These
concepts can be extended in 3D imaging through the use of specific tridimensional target object. The core of this paper is
focused on experimental characterization of seven different 3D laser scanner through the extraction of resolution,
accuracy and uncertainly parameters from 3D target object. The process of every single range map defined by the same
resolution leads to different results as z-resolution, optical resolution, linear and angular accuracy. The aim of this
research is to suggest a characterization process mainly based on resolution and accuracy parameters that allow a reliable
comparison between 3D scanner performances.
