System and Method for Inspecting Road Surfaces

摘要

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.

1. A method of inspecting a road comprising:
illuminating the road with at least one infrared source emitting light at first and second wavelengths corresponding to a water-absorption wavelength and an ice-absorption wavelength respectively; monitoring the road with a plenoptic camera system, wherein the at least one infrared source and the camera are mounted to a vehicle; detecting a backscatter intensity of the first and second wavelengths with the camera system to create a depth map of the road that includes data indicating water or ice on the road in response to the backscatter intensity associated with one of the first and second wavelengths being less than a threshold intensity; and outputting the depth map from the camera system to a controller.
