Patent ID: 8498836

Claim:
A method for detecting thermographic anomalies, comprising: using a sensor, obtaining a base-line profile of base-line thermographic data corresponding to a subject area, wherein the base-line profile is obtained as a reference for the subject area, and wherein the base-line profile comprises a first set of pixel values; storing the base-line profile; using the sensor, obtaining an operational profile of operational thermographic data corresponding to the subject area, wherein the operational profile comprises a second set of pixel values; automatically aligning the base-line profile and the operational profile; calculating a difference profile based, at least in part, on a difference between the second set of pixel values of the operational profile and a corresponding first set of pixel values of the stored base-line profile; receiving a plurality of thermographic zones and at least one condition for each of the plurality of thermographic zones, wherein each thermographic zone defines a portion of the subject area; and providing an indication based, at least in part, on the calculated difference profile for each of the plurality of thermographic zones, wherein the indication includes whether the at least one condition for each of the plurality of thermographic zones is met, and further wherein meeting the at least one condition for a given thermographic zone indicates a thermographic anomaly.
