Traits that can be extracted from a 3D point cloud of a young barley plant. From the XYZ point cloud (a) non-complex parameters like plant height (b), plant width (c), the convex hull (d) and the projected leaf area (e) can be extracted. Furthermore the leaf area density (f) can be derived. The number of leaves (g) and the respective leaf length (h) can be measured after identifying the individual plant organs. For each point the inclination and its height can be calculated resulting in a inclination (i) or height map (j)
