Determining the position of a sheet pile (1, 12) having faces (2) and edges (3) is achieved by at least one defined illumination zone (5, 5', 5'') produced on the sheet pile (1, 12) by diverging beams (4), and at least two boundaries (6, 6', 6'', 6''', 6'''', 6''''') of at least one illumination zone (5, 5', 5'') are detected and used to determine the position of the sheet pile (1, 12). A device is correspondingly configured with at least one illumination system (9, 9') and at least one receiver (7, 7'). A positioning system (10) is additionally fitted with a controller (11) in order to bring the sheet pile (1, 12) from the determined actual position (20) into its desired position (21).
