Thermal detection systems, methods, and devices

A thermal detection device comprising:

• an outer housing;
• a visual camera configured to generate a first signal related to a visual image of a scene;
• a first thermopile array including a first plurality of pixels;
• an array of temperature sensors positioned around the first thermopile array;
• a first control unit including a processor and a first memory, the first control unit connected to the first thermopile array and configured to generate a second signal related to a thermal image of the scene, the second signal associated with a temperature sensed by at least one of the first plurality of pixels in the first thermopile array;
• a second control unit including a processor and a second memory, the second control unit electrically connected to the visual camera and the first control unit, the second control unit configured to:
• receive the second signal from the first control unit,
• receive one or more output signals from the array of temperature sensors related to a temperature of the first thermopile array,
• generate a thermal map of the first plurality of pixels in the first thermopile array based on the one or more output signals from the array of temperature sensors, the thermal map related to how each pixel of the first thermopile array is affected by variations in temperature, and
• compensate the second signal based on the thermal map, and
• a display configured to display the visual image based on the first signal and the thermal image based on the compensated second signal.
