Vehicular radiometric calibration systems and methods

A method comprising:

• capturing, by an array of infrared sensors mounted on a first vehicle, a first thermal image of a scene during navigation of the first vehicle and/or while the first vehicle is stationary, wherein the first thermal image comprises a plurality of pixel values, and wherein each infrared sensor of the array is associated with a respective one of the plurality of pixel values;
• transmitting a request to a reference structure for temperature data associated with a portion of the scene, wherein the temperature data is associated with a blackbody object provided by the reference structure, and wherein the blackbody object comprises at least one of a housing of a traffic signal junction box, a housing of a traffic camera, an object on the first vehicle, an object on a second vehicle, or a sunshield in front of a subset of the infrared sensors of the array;
• determining the temperature data associated with the portion of the scene, wherein the portion is associated with a subset of the plurality of pixel values;
• wherein the determining the temperature data comprises receiving the temperature data from the reference structure in response to the request;
• and
• generating a first correction value based on the first thermal image and the temperature data, wherein the first correction value is based at least on the temperature data and pixel values of the first thermal image associated with the reference structure.
