A method for recognizing the orientation of a fruit having a central axis of symmetry passing through fruit concave parts, which are stalk cavity (cp) and calycin (c) of the fruit, the other parts of the fruit being convex, the fruit travelling on a fruit multiple lanes tape, formed by mesh elements and fruit holding flights having a number of recesses, each recess being provided with a central opening showing the fruit contained in the recess, characterized in that the method comprises: - a stopping step of a sample fruit (Fo) in a position selected between a position above a measuring instrument and a position below the latter; - an initial measurement step in which the measuring instrument measures its distance from the sample fruit (Fo) when targeting a concave part of the sample fruit (Fo), and the measuring instrument measures its distance from the same sample fruit (Fo) when targeting a convex part of the sample fruit (Fo); - an individual measurement step of each fruit to be treated travelling on the fruit multiple lanes tape by the same measuring instrument positioned in the same manner as in the initial measurement step; - a comparison step in which the distance measured in the individual measurement step of each fruit to be treated is compared with the distances measured in the initial measurement step of the sample fruit (Fo), in order to assess whether the distance measured in the individual measurement step is that one of a concave part of the fruit or that one of a convex part of the fruit; and - a check step that determines that the fruit is correctly oriented with its central axis of symmetry being in vertical position, if the distance measured in the individual measurement step is that one of a concave part of the fruit, or that the fruit is not correctly oriented if the distance measured in the individual measurement step is that one of a convex part of the fruit. - a stopping step of a sample fruit (Fo) in a position selected between a position above a measuring instrument and a position below the latter; - an initial measurement step in which the measuring instrument measures its distance from the sample fruit (Fo) when targeting a concave part of the sample fruit (Fo), and the measuring instrument measures its distance from the same sample fruit (Fo) when targeting a convex part of the sample fruit (Fo); - an individual measurement step of each fruit to be treated travelling on the fruit multiple lanes tape by the same measuring instrument positioned in the same manner as in the initial measurement step; - a comparison step in which the distance measured in the individual measurement step of each fruit to be treated is compared with the distances measured in the initial measurement step of the sample fruit (Fo), in order to assess whether the distance measured in the individual measurement step is that one of a concave part of the fruit or that one of a convex part of the fruit; and - a check step that determines that the fruit is correctly oriented with its central axis of symmetry being in vertical position, if the distance measured in the individual measurement step is that one of a concave part of the fruit, or that the fruit is not correctly oriented if the distance measured in the individual measurement step is that one of a convex part of the fruit.
