  The cultivation of orchard meadows provides an ecological benefit for
biodiversity, which is significantly higher than in intensively cultivated
orchards. The goal of this research is to create a tree model to automatically
determine possible pruning points for stand-alone trees within meadows. The
algorithm which is presented here is capable of building a skeleton model based
on a pre-segmented photogrammetric 3D point cloud. Good results were achieved
in assigning the points to their leading branches and building a virtual tree
model, reaching an overall accuracy of 95.19 %. This model provided the
necessary information about the geometry of the tree for automated pruning.
