The present invention relates to a method and apparatus for guiding an apparatus support towards at least one teat of a milk animal comprising moving the support (32) to a position where an udder is expected to be viewed; illuminating (33) a region expected to contain at least one udder with a source of structural light from the support; and viewing captured images (34) from said support by viewing the region with an image capturing device. According to the invention, said illuminating light is alternately turned on (33) and off (35) for elimination of disturbing reflections from the captured images, said captured images (34, 36) being of two types, one type when illuminated having disturbing as well as true light reflections, and another type when light is turned off having disturbing reflections only, said captured images being analysed (37) by forming the difference between said two types of captured images resulting in a difference image, said difference image being analysed (38) to identify possible teat candidates, one of which being selected as a target teat, the position of said target teat is determined for homing (43) of said support and any supported apparatus to said target teat. |
