Abstract: A system includes a color camera configured to detect visible light and ultraviolet (UV) light, a UV illuminator, and a processor configured to perform operations. The operations include causing the UV illuminator to emit UV light towards a portion of an environment and receiving, from the color camera, a color image that represents the portion illuminated by the emitted UV light and by visible light incident thereon. The operations also include determining a first extent to which UV light is attenuated in connection with pixels of the color camera that have a first color and a second extent to which UV light is attenuated in connection with pixels of the color camera that have a second color. The operations further include generating a UV image based on the color image, the first extent, and the second extent, and identifying a feature of the environment by processing the UV image.
