The invention relates to an apparatus (10) and method for handling moved piece goods (2), and a conveying, processing, and/or packaging plant including the apparatus (10). The apparatus (10) comprises at least one manipulator (5) for piece goods (2), at least one transport device (3) by which the moved piece goods (2) are transportable to a seizing range (4) of the at least one manipulator (5), and at least one movable optical detection device (40) assigned to the seizing range (4) and/or to a movement range of the at least one manipulator (5). The optical detection device (40) obtains space coordinates and/or position data and/or contour data of at least one piece good (2) that is being moved. The at least one manipulator (5) and/or further conveyor components of the apparatus (10) can be calibrated and/or controlled based on the detected space coordinates and/or position data and/or contour data.
