Abstract

A method is disclosed for instructing a user (20) for post-harvest trimming a bud (22) of a plant, preferably a cannabis plant. The method comprises presenting a side of the harvested bud (22) to an imaging system (16). The method also comprise illuminating, with a light source (14) system, a harvested bud (22) with illumination light (5). The illumination light (5) causes response light (7) from the harvested bud (22). The method also comprises an imaging system (16) receiving the response light (7) for forming an image of the harvested bud (22). In this method, (i) illuminating the bud (22) comprises illuminating with at least partially polarized illumination light (5) and/or (ii) detecting the response light (7) comprises polarization filtering the response light (7). The method also comprises an image processing system (100) determining, based on the formed image, a part of the bud (22) that is to be trimmed off. Further, the method comprises a user interface (24) providing, based on the image processing system (100) determining that said part of the bud (22) is to be trimmed off, an instruction to a user (20) to trim off said part.
