摘要： Various techniques are provided for improved detection of scene changes using a thermal imager. In one example, a method includes capturing a plurality of thermal images of a scene using a thermal imager. The method also includes detecting motion associated with the thermal imager during the capturing. The method also includes determining a temporal delay in response to the detected motion. The method also includes selecting first and second ones of the thermal images captured at corresponding first and second times separated by the temporal delay. The method also includes processing the first and second thermal images to generate a comparison thermal image identifying changes in the scene between the first and second times. Additional methods and systems are also provided.

摘要： Various techniques are disclosed to provide for improved human body temperature detection using thermal images of an inner canthus. In one example, a method includes capturing a thermal image of a human being using a thermal imager. The method also includes determining an uncompensated temperature measurement associated with an inner canthus of a face of the human being using corresponding pixels of the thermal image. The method also includes determining a correction term as a function of a distance between the thermal imager and the human being. The method also includes applying the correction term to the uncompensated temperature measurement to provide a corrected temperature measurement associated with the inner canthus to compensate for attenuation associated with the distance. Additional methods and systems are also provided.

摘要： Techniques are provided for variable sensitivity in infrared imaging. In one example, an infrared imaging system includes an infrared imager and a logic device. The infrared imager is configured to capture a first infrared image of a scene using a sensitivity setting. The logic device is configured to determine a temperature associated with the scene based on a second infrared image of the scene. The logic device is further configured to determine the sensitivity setting based on an ambient temperature associated with the infrared imager and the temperature associated with the scene. Related devices and methods are also provided.
