Integrating Real Tree Skeleton Reconstruction Based on Partial Computational Virtual Measurement (CVM) with Actual Forest Scenario Rendering: A Solid Step Forward for the Realization of the Digital Twins of Trees and Forests

Digital twins of forests (trees) are computational virtual recreations in which the entity distributions and physical processes real-world duplicated. It is expected that conventional forest science management can be undertaken a digital twin if recreation (tree) has accurate comprehensive enough information. However, due to various differences between current tree model real tree, these envisioned stay theoretical concept. In this study, we developed processing strategy partially integrated measurement (CVM) process into modeling workflow. Owing feature CVM, partial skeleton reconstruction procedures were considered have higher mechanical objectivity compared mathematical methods. The reason was novel method called diameter tape (VDT), could provide certain percentage elements using CVM. Technically, VDT able virtually measure diameters spatial distribution cross-sectional area trees, including basal area, from point clouds. simulated scenario tapes, observing clouds trees. Diameter stem branches obtained by two consecutive processes, one sample site another space. At same time, better or similar accuracy methods, i.e., Hough transform-based data sets. root-mean-square deviation (RMSE) retrieval at breast height (DBH) 1.02 cm, while DBH three methods varied 1.29 cm 1.73 cm. Based on results, actual rendering our plots further implemented. Beyond visual consistency, believe work might small solid step technological evolution models (trees).
