Fig 1. Image acquisition and analysis by the Scannalyzer 3D, plant-to-sensor imaging system.

(a) and (b) are raw images of a side-view and top-view (pea cv. Alma); (c) and (d) processed images showing the identification of the corresponding side-view and top-view objects (bright green plant). Estimated shoot biomass is the pixel sum of highlighted green objects in processed images (c, d). The height of the pink rectangle in (c) is the plant height. The perimeter enveloped by the pink line in (d) is the top-view convex hull.
