A vehicle includes at least one infrared source emitting light at first and second wavelengths corresponding to a water-absorption wavelength and an ice-absorption wavelength respectively. The vehicle further includes a plenoptic camera system configured to detect a backscatter intensity of the first and second wavelengths and generate a depth map that indicates water or ice on a road in response to the backscatter intensity associated with one of the wavelengths being less than a threshold intensity.
