Patent No. EP4018362 (titled "A Method And Apparatus For Determining The Identity Of An Animal Of A Herd Of Animals") was filed by Dairymaster on Aug 21, 2020. The application was issued on Nov 13, 2024.
Method for accurately identifying animals in a herd using a camera system instead of RFID tags. The method involves storing reference images of each animal cross-referenced with their identities. When a new image of an animal is captured, it is compared to the reference images until a match is found. The identified animal's image is then stored as a confirmed reference. This iterative comparison improves accuracy over time as more images are added. It also allows identifying animals without RFID tags.
