<p>A system for estimating the size and/or shape and/or position of an object such as a sheep mounted on a restraining means comprising a pair of video cameras and adjacent light sources, a multiplicity of elements of highly directional retro-reflective material attached to predetermined portions of said restraining means, a video digitizer board for digitizing the image received by each of said video cameras, an associated computer for storing the digitized image, said computer being programmed to search the stored digitized image to locate the bright spots created by said retro-reflective markers, following which the digitized image is search to locate changes in intensity in the image indicating the location of the edges of the sheep.</p> |
