Abstract:
(EN) A method of guiding a milking apparatus support towards at least one teat of a milk animal, characterized in that the method comprises the following steps: to move said support to a fixed start position within the stall, without any reference to any animal, to illuminate with a sheet of light from the support a region expected to contain at least one udder, to capture from said support images by viewing the region with a video camera, to analyze said captured images to identify possible teat candidates, to select one of said teat candidates as a target teat, to determine the position of said target teat, and to home in said support and any supported milking apparatus to said target teat.
