 This paper proposes a novel method for creating precise tree models from point clouds obtained through terrestrial laser scanning. The method uses a local approach to segment the point cloud into smaller sets corresponding to connected surface patches on the tree. These sets are then used to reconstruct the details of the tree and, step by step, the entire tree. The resulting model provides accurate measurements of the tree's branching structure and size properties, such as volume and branch size distribution. The method was tested on both real trees and 3D models, demonstrating its accuracy and reliability. This article was authored by Matthias Disney, Marcus Hallipanen, Miko Vasturanta, and others.
