Trees, bushes, and other plants are ubiquitous in urban environments, and realistic models of trees can add a great deal of realism to a digital urban scene. In recent years mobile laser scanning become an efficient technology for fast acquisition of large urban scenes. Such systems generate clouds of points that are often sparse, incomplete, and noisy representation of the real scenes. In this talk I present an approach that robustly reconstructs the existing trees in a scene. This is done by a series of optimizations that construct skeletal structure and foliage for a tree based on its points.

A significant benefit of our approach is its ability to reconstruct multiple overlapping trees simultaneously without segmentation. We demonstrate the effectiveness and robustness of our approach on many raw scans of different tree varieties.

This talk is composed of two sub titles (projects): 1) Automatic Reconstruction of Tree Skeletal Structures from Point Clouds 2) Texture-Lobes for Tree Modelling
