Method and device for displaying a dairy cow to be selected as probably lame from a stock

摘要

A device for recognizing a cow (13) to be selected as probably lame from a dairy cow stock has, in a defined spatial relation to an automatic milking parlor or similar lattice box (12), one of a cow (13) by means of a target trigger (16) in the lattice box (12) triggerable camera (11) on which a difference former (18) for this recording (15.1) and for an occasional reference recording (15.0) of the grid box (12) without cow (13) is connected downstream, and a curvature analyzer (23 ) for the course of the in the resulting image (19) scanned back line (21) of the cow (13). At least one program-controlled image processing (17) can serve to color the background (25) of the images (15.0, 15.1) and / or to colorize a strip (20) bounded by the back line (21) in the difference image (19).
