Introduction

The Fragmenter is a software component for the fragmentation analysis of 3D models of muck piles and riprap. It features the delineation of single particles on a 3D model by a combined 3D surface and image analysis, the sizing of particles based on the delineated surface patches, and the determination of the particle size distribution. The fragmentation analysis runs fully automatically and results are displayed in a particle size distribution plot and as individual delineated particles on the 3D model and on the corresponding ortho-photo.

This user manual addresses all topics related to the Fragmenter i.e. installation, user interface, features and operations. Let us know if we can support you, and give us your valuable feedback. Only this way it remains possible to keep the system both, flexible enough for broad usage and sufficiently specific for your applications. 

We wish you success with the Fragmenter.
