摘要：The invention relates to a method for determining the orientation of an upperpart (1) of a stack (2) of piece goods, in particular of a stack of metal sheets. An image ofthe upper cover layer of the stack (2) of piece goods is acquired by an image acquisitiondevice (6), and a relative orientation of the upper cover layer is determined therefrom byan image evaluation module. One image (15, 16) each of a first (7) and a second (8)position of the stack (2) of piece goods is acquired, and an image analysis is performedfor each image (15, 16) by an image analysis and comparison module (13). A contour (17)is extracted and a first (18) and second (19) piece of position information are determined.A distance (21) is determined from the first (18) and second (19) pieces of positioninformation, wherein a part model (22) is created from the extracted contours (17) andthe distance (21) by the image analysis and comparison module (13). The part model iscompared with a stored reference model (23). If there is a deviation between the partmodel (22) and the reference model (23), a piece (9) of transformation information isdetermined.
