1. A system comprising:
an optical filter configured to attenuate visible light and pass near-infrared light;
an image sensor configured to detect light reflected by a surface after the reflected light passes through the optical filter and generate image data comprising a detected near-infrared portion of the light reflected by the surface, wherein the image data comprises a plurality of pixels; and
processing circuitry configured to:
receive the image data from the image sensor; and
determine near-infrared glare information based on the received image data by:
determining, for the plurality of pixels, respective intensity values; and
identifying multiple pixels of the plurality of pixels having an intensity value that exceeds a predetermined threshold intensity value.
