Abstract

Abstract The invention provides a method and apparatus for remote sensing of livestock, using a thermographic image sensing system, in order to determine one or more of the number, weight, location, temperature, carcass pH, etc., of animals in a surveillance area. A thermographic image comprising pixels of the area is sent to a digitizing board in a microcomputer, where the image is converted into a number array. The numbers are then interpreted by software to provide the desired information in a decipherable form.

Claim 2
Independent Claim 89 words
An apparatus for remote sensing of weight information about an animal in an area and making said information available in a decipherable form to an observer, comprising: means without human operation for remotely obtaining a thermographic image of the area, which image can be used directly or indirectly to provide a weight of an animal in the area; means for converting maid image into computer readable form; means for interpreting said form to provide said information; and means for displaying said information in a decipherable form to said observer.

Claim 9
Dependent Claim 53 words
An apparatus as defined in claim 3, wherein said means for interpreting said form to provide said information includes processing means for segmenting a group of pixels associated with said animal from pixels associated with background thereby providing an animal profile of said animal, and applying a unique identifier to said animal profile.
Claim 10
Dependent Claim 46 words
An apparatus as defined in claim 8 wherein said processing means also includes means for segmenting a single group of pixels associated with a plurality of animals in said area and determining an approximation of a number of animals associated with said single group of pixels.
Claim 11
Dependent Claim 45 words
An apparatus as defined in claim 9 wherein said processing means includes means for counting said unique identifier and said approximation of a number of animals associated with said single group of pixels, to determine an estimate of a number of animals in the area.
Claim 12
Dependent Claim 32 words
An apparatus as defined in claim 8 wherein said processing means includes means for counting a total number of pixels in said animal profile to determine an approximate weight of said animal.
Claim 13
Dependent Claim 41 words
An apparatus as defined in claim 8 wherein said processing means includes means for determining a centre of said animal from locations of all pixels in said animal profile and then determining an approximate position of said animal in the area.
Claim 14
Dependent Claim 34 words
An apparatus as defined in claim 8 wherein said processing means includes means for determining an approximate absolute or relative temperature of said animal based on average brightness of pixels in said animal profile.
