Apparatuses, systems, and methods for thermal imaging

A thermal imaging system comprising:

• an infrared (IR) imager configured to acquire IR image data of the field of view of the remote video sensor;
• a temperature control chamber enclosing the IR imager and configured to thermally isolate the IR imager;
• one or more temperature sensors thermally coupled to the IR imager;
• and
• video analysis circuitry operably coupled to the IR imager, wherein the video analysis circuitry is configured to:
• receive operating temperature data from the one or more temperature sensors;
• and
• compare the operating temperature data with one or more operating thresholds;
• and
• in an instance in which the operating temperature fails to satisfy the one or more operating thresholds, modify the operating temperature of the IR imager.

A thermal imaging system comprising:

• an infrared (IR) imager configured to acquire IR image data of a field of view of the IR imager;
• a first field reference positioned within the field of view of the IR imager, wherein the first field reference is calibrated to a first temperature;
• a second field reference positioned within the field of view of the IR imager, wherein the second field reference is calibrated to a second temperature;
• video analysis circuitry operably coupled to the IR imager, wherein the video analysis circuitry is configured to:
• receive first temperature data of the first field reference;
• receive second temperature data of the second field reference;
• receive IR image data from the IR imager;
• and
• calibrate the IR imager based upon the first temperature data, the second temperature data, and the IR image data.

A thermal imaging system comprising:

• a remote video sensor comprising:
• a visible imager configured to acquire visible image (VIS) data of a field of view of the remote video sensor;
• and
• an infrared (IR) imager configured to acquire IR image data of the field of view of the remote video sensor;
• and
• video analysis circuitry operably coupled to the remote video sensor, wherein the video analysis circuitry is configured to:
• receive VIS data from the visible imager;
• receive IR image data from the IR imager;
• analyze the VIS data to determine one or more target indicators of the VIS data associated with one or more faces within the field of view of the remote video sensor;
• map the one or more target indicators on the IR image data to generate a target modified IR image;
• analyze the target modified IR image to determine a facial temperature associated with each of the one or more faces within the field of view;
• and
• generate a target and temperature modified IR image that includes the one or more target indicators and the facial temperatures.
