1. A method of grading a characteristic of an animal, the method comprising:
- a) determining the presence of an animal in an animal detection area;
b) capturing an image from a back of the animal by means of image capture means located above the animal detection area, the image being captured in dependence upon the determination of the presence of an animal;
c) analyzing, via a computing device the image to determine a plurality of angles identified at points over the back of the animal; and
d) calculating, via the computing device a graded score from a combination of the angles;
wherein analyzing the image to determine the plurality of angles identified at points over the back of the animal includes identifying a plurality of anatomical points over the back of the animal at the outer edges of an outline of the image of the back of the animal.

Abstract
A method of and apparatus for grading a characteristic of an animal is described. The animal is guided to a detection area whereupon an image of the back of the animal is captured. Analysis of the image identifies anatomical points and determines angles at these points. The angles are then used to calculate a grading for a characteristic of the animal. An embodiment is presented for automating the determination of body score condition in dairy cows using seven angles determined at three anatomical points from an image over the back of the cow.

15. Apparatus for grading a characteristic of an animal, the apparatus comprising:
- triggering means operative to determine the presence of an animal in an animal detection area;
image capture means located above the animal detection area that is operative to capture an image from a back of the animal, the image capture means being operative in dependence on operation of the triggering means;
signal processing means operative to analyze the image and determine a plurality of angles identified at points over the back of the animal and to calculate a graded score from a combination of the angles;
wherein signal processing means operative to analyze the image and determine a plurality of angles identified at points over the back of the animal includes identifying a plurality of anatomical points over the back of the animal at the outer edges of an outline of the image of the back of the animal. - View Dependent Claims (16)
