<p>A system for acquiring images for identifying signs on postal packages (7), in which each package is moved by pinching between a wall of a housing comprising a longitudinal slot and a conveyor, comprises in a housing (3) a lighting module (25, 26) having two lighting units that are symmetric with respect to the slot so as to light a surface (8) delimited by the slot (5), a camera (22) for forming an image of said lit surface (8), a means of polarization (23, 24) being disposed between said lighting module (25, 26) and said surface (8) and a polarizing filter (27) being disposed between said camera (22) and said surface (8). The slot (5) is closed by a flush transparent rigid wall (6) against which each package is applied.</p> |
