a Software pipeline for combining Odos 3D images with profilometer data to refine the leaf position map and obtain information to precisely position the leaf probe. b Leaf segmentation and probing location candidates. Image is a top view of the 3D point clouds obtained with the laser profilometer. Red points are rejected by 3D region growing segmentation. Any other color represents a different leaf segment. A feasible probing location is shown with a white sphere and the surface normal is shown as a grey line
