System and method for detecting thermal anomalies
First Claim
1. A system for detecting a thermal anomaly in a desired location on an animal, comprising:
- a first imager for capturing a visual image of the animal that includes a feature;
a second imager for capturing a thermal image of the animal; and
a processor coupled to the first and second imagers that determines from the visual image a region encompassing the feature in the thermal image, that identifies based on the determined region, a second region, in the thermal image, and that analyzes the second region for the thermal anomaly,wherein the second region does not include the feature.

Abstract
A system and method for detecting a thermal anomaly in humans and/or livestock. In one embodiment, the system includes an image capturing component that captures a visual image of incident light in a screening area, the image capturing component further operable to determine a first coordinate in the captured image, such as the location of a person'"'"'s eyes. The system further includes a radiation capturing component operable to capture a thermal image of incident radiation in the screening area, the radiation capturing component further operable to determine an analysis area in the captured thermal image based upon the first coordinate in the captured light image. Finally, the system includes a processing component for determining thermal characteristics about the analysis area. As a result, if the thermal characteristics correspond to an alarm event, then an alarm may be triggered and the person or animal may be isolated for further health screening.

7. A method for detecting a thermal anomaly on an animal, the method comprising:
-
passing the animal through a screening area; capturing, by one or more imagers, a visual image and a thermal image of the animal, as the animal passes through the screening area; identifying a region of interest in the visual image; determining, based on the region of interest in the visual image, a corresponding region of interest in the thermal image; identifying, based on the determined region of interest, a second region of interest in the thermal image; analyzing the second region of interest for the thermal anomaly; and outputting the analysis, wherein the analyzing of the second region of interest does not include analysis of the determined region of interest. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A thermal anomaly detection system for detecting whether a temperature of an animal exceeds a threshold level, comprising:
-
a combination visual and thermal imager configured to capture a visual image of the animal that includes a feature and a thermal image of the animal; and a processor coupled to the imager that determines from the visual image a region encompassing the feature in the thermal image and configured to identify, based on the feature in the visual image, a second region in the thermal image and to analyze the second region which is less than the entire thermal image for a thermal anomaly, wherein the analyzed second region does not include the feature associated with the visual image. - View Dependent Claims (15, 16, 17, 18, 19)
