Fig. 1. — Schema of the scanning unit (PlantEye^R). (A) How the 3D object (canopy; green) is reconstructed from the set of 2D images (50–80 images per second) of the reflection (red) of laser line (green) projected on canopy. (B) The distances (to the ground, D_G, to the barcode target, D_T, and to the plant, D_P) that are used in the computation. T_H represents the target height and is used as a reference height for calculations. Pot height is set for the scanners and represents the height below which the data from the 3D data clouds are not used in the calculations.
