In the last decade, three-dimensional reconstruction of plants has gained a noticeable importance, in particular for the possibility of collecting data correlated to biomass, leaves area, etc. Different sensing technologies are available for 3D imaging, as for instance laser scanning, or stereoscopic reconstruction: however, practical application is still limited by high costs, or high speed data processing demand. For the present work depth sensing cameras technology is implemented. Measurements were repeated on 17 different dates, between April and June, on a jujube (Ziziphus jujube) plant, collecting 3D scans through a Kinect I sensor. 3D images were analysed in order to estimate the three-dimensional volume (Vk) of the canopy and the leaf area, and the results were compared with biomass related data arising from hand measurements (volume and leaf area index, LAI).
