1. A system comprising:

  • a first imaging device configured to acquire infrared-based image data corresponding to only a central region of wheels of a vehicle moving through a field of view of the imaging device;

    a second imaging device configured to acquire infrared-based image data corresponding to a lower outer region of the wheels of the moving vehicle, wherein the lower outer region does not overlap with the central region, wherein the infrared-based image data acquired by the first and second imaging devices is at least partially based on infrared within the mid-wavelength infrared (MWIR) radiation spectrum; and

    a computer system for evaluating the wheels based on the infrared-based image data, wherein the evaluating includes, for each imaged wheel of the moving vehicle;

    generating temperature distribution data for the wheel based on the infrared-based image data acquired by the first and second imaging devices; and

    evaluating the wheel using the temperature distribution data.
