Reflective rub-off oestrus indicator patch for digital image detection

摘要

An oestrus indicator patch comprises a fabric layer configured to be secured to an animal; a reflective layer secured to the fabric layer and a non-reflective coating adhered to and partially covering the reflective layer wherein the non-reflective coating arranged to be at least partially removed from the indicative patch during mounting activity. An oestrus detection system comprises: a digital image capture device positioned to capture one or more digital images of an animal on which an indicator patch has been secured wherein the indicator patch includes a reflective layer and a non-reflective coating adhered to and partially covering the reflective layer wherein the non-reflective coating arranged to be at least partially removed from the indicative patch during mounting activity; an image selector configured to select one or more digital images from the captured digital image (s) that includes an image of the indicator patch and an image measurer configured to measure the visual appearance of the indicator patch in the selected digital image against a visual appearance threshold.
