System And Method For Estimating The Depth Of At Least One Pothole That Is At Least Partially Filled With Water, And Corresponding Driver Assistance System

Abstract: The present application relates to a system (5) for estimating the depth of at least one pothole (1, 1a), that is at least partially filled with water, using a driver assistance system (13) that is provided in a vehicle (11), the system (5) comprising the following: at least one optical camera sensor which is configured to detect the at least one pothole (1, 1a), that is at least partially filled with water, based on camera data that is generated by the optical camera sensor; at least one thermal camera sensor (8) which is configured to determine a road surface temperature, the road surface (2) comprising the surface of the at least one pothole (1, 1a) that is at least partially filled with water, the determination of the road surface temperature being based on the temperature determination of pixels in a thermal pixel image (9) that is generated by the at least one thermal camera sensor (8); a processor which is configured to determine, based on the road surface temperature detected by the at least one thermal camera sensor (8), the surface temperature of the at least one at least pothole (1, 1a) that is is at least partially filled with water and is detected by the at least one optical camera sensor, and which is also configured to estimate the depth of the at least one pothole (1, 1a), that is at least partially filled with water, based on the surface temperature of said pothole. The application also relates to: a method for estimating the depth of at least one pothole that is at least partially filled with water; and a driver assistance system implementing such a method.
