Title: PORTABLE APPARATUS AND METHOD FOR CLASSIFYING TEATS WITH RESPECT TO SIZE MEASURES
Abstract:
A portable apparatus (130) classifies teats (T1) with respect to size measures. A camera (131) records image data representing a scene (125) containing a teat (T1 ) of a dairy animal. The scene (125) also contains first and second markers (121,122) projected onto the teat (T1 ) by a respective collimated light source (111;112) located at a well-defined distance (DL) from one another. A processing unit (135) in the portable apparatus (130) calculates at least one size measure (X, Y) of the teat (T1) based on the recorded image data. This, in turn, forms a basis for determining a size-related classification of the teat (T1), which for example is associated with a recommended teatcup liner (TCLR) for the diary animal.
