Revealing the skeleton from imperfect point clouds

Quantifying our surrounding environment in terms of sizes and orders has always been of interest, because it enables us to visualize, describe and interpret our environment. In the last decade terrestrial laser scanners became available as a tool to measure objects in our surrounding environment. Terrestrial laser scanning samples surfaces with...

Automated detection of branch dimensions in woody skeletons of leafless fruit tree canopies

Light driven physiological processes of tree canopies need to be modelled based on detailed 3Dcanopy structure – we explore the possibilities offered by terrestrial LIDAR to automatically represent woody skeletons of leafless trees as a basis for adequate models of canopy structure. The automatic evaluation method for LIDAR data of fruit trees...

SkelTre - Fast Skeletonisation for Imperfect Point Cloud Data of Botanic Trees

Terrestrial laser scanners capture 3D geometry as a point cloud. This paper reports on a new algorithm aiming at the skeletonisation of a laser scanner point cloud, representing a botanical tree without leafs. The resulting skeleton can subsequently be applied to obtain tree parameters like length and diameter of branches for botanic...

Applications for point cloud skeletonizations in forestry and agriculture

In recent years, both airborne and terrestrial laser scanning developed to a standard technique for acquiring information on terrestrial landscapes. Here forest inventory and orchard management is considered. Inventory and parameterization of individual trees in orchards and forests are of large interest in nowadays society because of the...
