First Claim
1. An apparatus for measuring the physical characteristics of first and second animals positioned respectively within first and second target zones, each of the animals having first and second sides and a top portion, said apparatus comprising:
- (a) an animal positioning device for defining the first and second target zones and for positioning the animals therewithin, said animal positioning device comprising first and second positioning chutes, each said first and second positioning chute having first and second sides, a floor and an upper portion and each said first and second positioning chute having;
(b) a first camera array disposed on said first side thereof for obtaining a first range image of the animal positioned within said chute comprising an image of the first side of the animal;
(c) a second camera array disposed proximate to said upper portion thereof for obtaining a second range image of the animal positioned within said chute comprising an image of the top portion of the animal;
(d) a third camera array disposed proximate said second side thereof for obtaining a third range image of the animal positioned within said chute comprising an image of the second side of the animal; and
(e) data processing means operably associated with said first, second and third camera arrays for acquiring said first, second and third range images produced thereby to produce a plurality of acquired range images and for processing said plurality of acquired range images to produce a three-dimensional point cloud data set corresponding generally to the shape of at least a portion of the surface of the animals.

Abstract
A method and apparatus for measuring the physical characteristics of livestock animals such as cattle and hogs. The apparatus of the invention includes a plurality of strategically positioned cameras that are used to obtain data concerning volumetric, curvilinear (surface) and linear measurements of livestock animals such as cattle and hogs and the full carcasses thereof. In accordance with the method of the invention, the data is analyzed to provide information that substantially assists the commercial producer of livestock animals in producing a high-quality end-product for the consumer while adding profitability to the enterprise.

10. An apparatus for measuring the physical characteristics of first and second animals positioned respectively within first and second target zones, each of the animals having first and second sides and a top portion, said apparatus comprising:
-
(a) an animal positioning device for defining the first and second target zones and for positioning the animals therewithin, said animal positioning device comprising first and second positioning chutes, each said first and second positioning chute having first and second sides, a floor and an upper portion and each said first and second positioning chute having; (b) a first camera array disposed on said first side thereof for obtaining a first range image of the animal positioned within said chute comprising an image of the first side of the animal said first camera array comprising a range camera; (c) a second camera array disposed proximate to said upper portion thereof for obtaining a second range image of the animal positioned within said chute comprising an image of the top portion of the animal said second camera array comprising a range camera; (d) a third camera array disposed proximate said second side thereof for obtaining a third range image of the animal positioned within said chute comprising an image of the second side of the animal, said third camera array comprising a range camera; and (e) data processing means operably associated with said first, second and third camera arrays for acquiring said first, second and third range images produced thereby to produce a plurality of acquired range images and for processing said plurality of acquired range images to produce a three-dimensional point cloud data set corresponding generally to the shape of at least a portion of the surface of the animals and then to analyze said three-dimensional point cloud data set to produce a three-dimensional mesh surface image corresponding generally to the shape of at least a portion of the animals. - View Dependent Claims (11, 12, 13)

14. A method for measuring the physical characteristics of an animal having first and second sides and a back, said animal being positioned within a target zone having first and second sides, an upper portion and a bottom portion using an apparatus comprising means for defining the target zone, a first camera disposed on said first side of said target zone, a second camera disposed on said second side of target zone, a third camera disposed proximate said upper portion of said target zone and data processing means operably associated with said first, second and third cameras for processing data received from said cameras, said first, second and third cameras, said method comprising the steps of:
-
(a) positioning the animal within the target zone; (b) using the first camera, obtaining a range of image of at least a portion of the first side of the animal; (c) using the third camera, obtaining a range of image of at least a portion of the back of the animal; and (d) entering into the data processing means, said range images to produce a plurality of entered range images and for processing said plurality of acquired range images to produce a three-dimensional point cloud data set corresponding generally to the shape of at least a portion of the surface of the animal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method for measuring the physical characteristics of an animal having first and second sides disposed on either side of a median plane and a back portion, said animal being positioned within a target zone having first and second sides, a top and a bottom using an apparatus comprising an animal positioning device for defining the target zone, a first camera disposed on one of said first and second sides of said target zone, a second camera disposed proximate said top of target zone and data processing means operably associated with said first and second cameras for processing data received from said first and second cameras, said method comprising the steps of:
-
(a) positioning the animal within the target zone; (b) using the first camera, obtaining a range image of at least a portion of the first side of the animal; (c) using the second camera, obtaining an image showing the position of the median plane; (d) using the data processing means, acquiring said first range image to produce a first acquired range image, acquiring said image showing the position of the median plane to produce an acquired median plane image and processing said first acquired range image and said acquired median plane position image to form a reverse duplicate analog of said first acquired range image to represent an inferred range image of at least a portion of the second side of the animal; and (e) using the data processing means, the first acquired image and the inferred range image of at least a portion of the second side of the livestock animal to form a three-dimensional data set representing at least a portion of the surface of the animal. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48)
