PASSIVE REFERENCE OBJECT FOR THERMOGRAPHIC CAMERA

Abstract:

A system for determining the temperature of a subject includes a thermographic camera and a passive reference object fixedly positioned relative to the thermographic camera with at least a portion of the reference object in a line of sight of the camera. In operation, the system captures temperature information of a subject and the reference object using the thermographic camera. The reference object has known physical properties, such that the reference object can be used as a base line for the system to determine fluctuations in the temperature information. The fluctuations are then removed from the temperature information of the subject to increase an accuracy of the temperature reading of the subject.
