Definitions
- the present application relates to a system for estimating the depth of at least one at least partially water-filled pothole by a driver assistance system provided in a vehicle. Furthermore, the application relates to a method for estimating the depth of at least one at least in part
- potholes are caused by the pavement being subjected to severe stress from severe weather and the sustained pressure of oncoming traffic. Potholes are caused by the expansion and contraction of water that has seeped into the ground beneath the asphalt and pavement.
- US 9626763 B1 discloses a system for detecting potholes, comprising: an input interface to configured to: receive sensor data of a vehicle; a vehicle event recording processor configured to: determine a pothole based at least in part on the sensor data; storing pothole data associated with the pothole, the pothole data including pothole video; and providing the pothole data, wherein a pothole rating of the pothole is determined and stored based at least in part on the pothole data, the pothole rating including a drive avoidance rating, a visibility rating, or any combination thereof.
- a road surface condition detecting device mounted on a vehicle comprising: laser beam scanning means for scanning with a laser beam a road surface in a transverse direction; image pick-up means for picking up a scanning locus of the laser beam in an oblique direction to generate cross-sectional data of the road surface; light receiving means for receiving a laser beam reflected from the road surface in an oblique direction to generate crack data of the road surface; road distance detecting means for measuring distances to the road surface from three positions on a line in the longitudinal direction of the vehicle to generate longitudinal profile data of the road surface; running distance detection means for measuring a running distance of the vehicle; and recording means for recording data generated by the image pickup means, the light receiving means and the distance detecting means, respectively, together with the running distance data generated by the running distance detecting means.
- the dependent claims list further advantageous measures which can be combined with one another as desired to achieve further advantages.
- a system for estimating the depth of at least one at least partially water-filled pothole by a driver assistance system provided in a vehicle comprising the following: at least one optical camera sensor configured to at least detect an at least partially water filled pothole based on camera data generated by the optical camera sensor, at least one thermal camera sensor configured to determine a road surface temperature, the road surface covering the surface of the at least one at least partially water filled pothole, wherein the determination of the road surface temperature is based on the temperature determination of the pixels in a thermal pixel image generated by the at least one thermal camera sensor, a processor configured to determine the surface temperature of the at least one at least in part mi t water-filled pothole detected by the at least one optical camera sensor based on the road surface temperature detected by the at least one thermal camera sensor, and is further configured to determine the depth of the at least one at least partially water-filled pothole based on its surface temperature.
- a pothole can also be a crack in the road.
- a water filled pothole may also include water and another fluid.
- the pothole filled with water is completely filled with water. It has been found that open road cracks/potholes are visible from a considerable distance and thus can be detected by systems/methods as mentioned above in the prior art. However, it has also been found that these methods are not reliable in all environmental conditions, particularly when these potholes are filled with water due to rain, snow or some other reason. Furthermore, until now it has been very difficult to obtain the depth information of these potholes. Therefore, if the vehicle encounters such a (deep) pothole filled with water, a serious accident or driving discomfort may result. In addition, the vehicle can be severely damaged, particularly from deep potholes, resulting in increased maintenance and other operational expenses.
- the invention is based on the further finding that the surface temperature is lower for deep water-filled potholes compared to narrower water-filled potholes.
- the invention thus enables the depth of at least one pothole that is at least partially filled with water to be determined by combining a thermal camera sensor and an optical camera sensor, so that a pothole with a large depth can be avoided. This allows for a safe and comfortable ride for the driver. In addition, damage otherwise caused by deep potholes can be avoided.
- the invention enables the depth of a pothole to be estimated by detecting a temperature reached by combining sensor signals obtained from the optical camera sensor and the thermal camera sensor.
- such cameras are already installed in a vehicle.
- By determining the temperature for each pixel in the thermal pixel image it is possible to determine the depth of water-filled potholes in any environment, even in fog, rain or at night. Especially in fog, when the front scene is usually not even visible, or in severe weather conditions, a depth estimate for potholes filled with water can be given.
- the thermal camera is a high speed infrared imaging camera that allows the generation of high speed thermal imaging with good resolution at a fast frame rate.

- the camera preferably consists of or uses a CNN (Convolutional Neural Network) for fast and accurate real-time segmentation.
- CNN Convolutional Neural Network
- Alternative other image processing algorithms such as other artificial neural networks or pattern recognition can be used.

In another embodiment, the at least one optical camera sensor and the at least one thermal camera sensor are located at the top of the windshield. This allows a large field of view to be achieved. As a result, road images far away from the vehicle can be created. This allows deep potholes to be detected at a great distance.

- the blackbody emission concept can be used to determine the surface temperature, so that a precise determination of the temperature reached on a pothole surface is possible. Integrating Planck's law over all frequencies gives the total energy per unit time per unit area radiated by a blackbody maintained at a temperature T. This is known as the Stefan-Boltzmann law.
- the Stefan-Boltzmann law describes the energy radiated by a blackbody as a function of its temperature. More specifically, the Stefan-Boltzmann law states that the total energy radiated per area A of a blackbody over all wavelengths per unit time (also known as the emissivity of a blackbody) is directly proportional to the fourth power P of the thermodynamic temperature T of the blackbody: where s is the Stefan-Boltzmann constant.
- the blackbody must absorb or internally generate that amount of power P for the given area A.
- the processor is configured to estimate the depth of the at least one at least partially water filled pothole using a trained machine learning approach.
- the depth can thus be estimated by a trained deep learning approach, for example.
- the training data can be easily derived from real images of water-filled potholes and a (manually or automatically) measured depth of the corresponding potholes filled with water. Using this approach, potholes of various shapes and depths, etc. can be readily determined.
- the processor is configured to determine the depth of the at least one at least partially water filled pothole by comparing the surface temperature of the water filled potholes to a temperature of the surrounding surface and/or by comparing the surface temperatures of the water filled potholes to each other appreciate. This allows a quick estimate to be achieved.
- the system further includes at least one speed camera configured to measure the beam reflected from the road surface, wherein the processor is further configured to determine the depth of the at least one pothole at least partially filled with water estimate the reflected beam and the surface temperature of the at least one pothole at least partially filled with water.
