Method and apparatus for determining the identity of an animal of a herd of animals

Abstract

A rotary milking platform () comprises a plurality of stalls () and an RFID animal identifying system () for identifying animals entering the stalls () of the platform (). A microprocessor () reads signals from an image capturing device () and computes a feature vector from the captured image of each animal. A plurality of reference feature vectors comprising respective matrices of metrics already derived from images of the respective animals captured by the image capturing device () are stored and cross-referenced with the identity of the respective animals. The microprocessor () compares computed feature vectors of each animal with the stored reference feature vectors until a best match has been determined with one of the reference feature vectors. The identity of the animal of that matching reference feature vector is then determined as the identity of the animal of that computed feature vector. The determined identity of the animal in the relevant stall () is compared with the identity of the animal determined for that stall () by the RFID system (). On a favourable comparison the identity of the animal determined from the captured image of that animal is confirmed as the identity of the animal. In the event of a conflict between the two identities being determined, a conflict alert signal is produced.
