Reconstructing 3D Tree Models from Instrumented Photographs

Abstract  In this article, we propose a hybrid approach to solving the inverse problem of reconstructing a foliaged tree. Our method involves first constructing the skeleton(trunk and the major branches) of the tree, and then applying an L-system starting from this skeleton. L-systems are one of the better-known procedural models in the graphics community, especially after their popularization by Lindenmayer and Prusinkiewicz. The “Related Work” sidebar provides some background on L-systems.
