Method and device for the removal of a part of a crop, such as a leaf (14). To this end, the crop is ap-proached from a low position with vision techniques and the stem (12) and the parts protruding therefrom are observed from beneath. Based upon the number of images observed, an arm is controlled and moved towards the relevant stalk (13). This movement is primarily parallel to the stalk and is performed from a low proximity position. When the stalk (13) is approached, said stalk (13) is positioned within an opening between two rotating parts (3). The stalk is grasped by means of rotation and the stalk is moved in respect of the arm so that the cutting point of the stalk is manipulated to-wards the arm. The stalk (13) is subsequently cut through and the leaf is disposed of.

L'invention porte sur un procédé et sur un dispositif pour le retrait d'une partie d'une plante de culture, telle qu'une feuille (14). A cette fin, la plante de culture est approchée à partir d'une position basse avec des techniques de vision, et la tige (12) et les parties faisant saillie à partir de celle-ci sont observées à partir du dessous. En fonction du nombre d'images observées, un bras est commandé et déplacé vers la queue (13) concernée. Ce mouvement est principalement parallèle à la queue et est effectué à partir d'une position de proximité basse. Lorsque la queue (13) est approchée, ladite queue (13) est positionnée à l'intérieur d'une ouverture entre deux parties rotatives (3). La queue est saisie par rotation, et est déplacée par rapport au bras de telle sorte que le point de coupe de la queue est manipulé vers le bras. La queue (13) est ensuite totalement coupée et la feuille est rejetée.
