<p>The present invention relates to a method for detecting a node (5) and/or a bud (8) from a stalk (1) of a graminaceous plant comprising: obtaining a picture of at least a part of the stalk (1), showing the projection of a lateral view of the stalk (1), and analyzing the obtained picture, wherein the distance of a position of the outline of the projection of the lateral view from a straight line that is parallel to the longitudinal axis (X) of the stalk (1) as a function of the longitudinal position (L) of the stalk (1) is determined, the algebraic sign of the first derivation (f ) of this function (f) is calculated, and the longitudinal position (Ln) of the node (5) and/or the bud (8) is detected at such longitudinal position (Ln) where the first derivation (f ) changes its algebraic sign. Furthermore, the present invention relates to a corresponding system for detecting a node (5) and/or a bud (8).</p> |
