Misurare e rappresentare il “verde”: dal rilievo digitale alle piattaforme di training virtuale/Measuring and representing “green” elements: from digital surveying to virtual training platforms.

The paper deals with the topic of surveying greenery, the complexity of its acquisition and repre-sentation, as well as the current challenges related to the construction of detailed digital duplicates of the individual plant, geometrically reliable and usable within immersive platforms. Artificial Intelli-gence algorithms come to the aid of simplifying the process of 3D reconstruction of greenery, but without being able to restore the integrity of the distinctive features of the species, making the critical interpretation of the drawer still necessary. The text describes the experiments conducted within the multidisciplinary research project Demetra, for the evaluation of the reliability of semi-automatic algorithms in the production of reality-based geometric models of a hazel tree plant and the sub-sequent development a training platform in a virtual environment for agricultural operators, with a focus on tree pruning. The research intends to test an operational method for 3D representation of plant elements in the digital context, using data integrated from different tools and according to a parametric logic of Digital Twins, such that it can be used for future developments in agriculture and in virtual training of professionals in the field
