Detecting patterns on object surface e.g. in warehouse, involves evaluating acquired images in computer so that 3D and 2D images can be detected with bright and dark field surface illumination respectively

摘要

The method involves alternately illuminating (4) the surface of the object (2) with bright field and dark field illumination, acquiring (1) at least one image with bright field illumination and/or with dark field illumination and evaluating the images in a computer (3) using neural network so that 3D and 2D images can be detected with the bright and dark field illumination respectively. AN Independent claim is also included for the following: an arrangement for detecting patterns on object surface.
