In the last decade, the interest on instrumentation for three-dimensional (3D) reconstruction has increased, in particular for the possibility of characterizing phenology and physical characteristics of agricultural products. The present work evaluates the suitability of a low-cost instrument for fast generation of three-dimensional digital models: focus of the present study is the evaluation of accuracy of 3D point clouds. The instrument relies on an IR-depth sensing camera and an RGB camera, both allowing rapid digital reconstruction of scanned objects. The evaluation has been carried on a bunch of grapes under different operating parameters (e.g. scanning speed, distances of the target from the instrument) reproduced in laboratory conditions.

Abstract
In the last decade, the interest on instrumentation for three-dimensional (3D) reconstruction has increased, in particular for the possibility of characterizing phenology and physical characteristics of agricultural products. The present work evaluates the suitability of a low-cost instrument for fast generation of three-dimensional digital models: focus of the present study is the evaluation of accuracy of 3D point clouds. The instrument relies on an IR-depth sensing camera and an RGB camera, both allowing rapid digital reconstruction of scanned objects. The evaluation has been carried on a bunch of grapes under different operating parameters (e.g. scanning speed, distances of the target from the instrument) reproduced in laboratory conditions.
