Abstract

A system for pothole detection comprises an input interface configured to receive sensor data and a pothole detector configured to determine a pothole based at least in part on the sensor data using a model, wherein the model is used to classify sensor data; and store pothole data associated with the pothole, wherein the pothole data comprises a pothole video.

Claims

1. A system for pothole detection, comprising:

an input interface configured to;

receive sensor data;

a pothole detector configured to;

determine a pothole based at least in part on the sensor data using a model, wherein the model is used to classify sensor data; and

store pothole data associated with the pothole, wherein the pothole data comprises a pothole video.

2. The system of claim 1, wherein the pothole video comprises a short video.

3. The system of claim 1, wherein pothole data additionally comprises one of:

location data, vehicle type data, vehicle speed data, pothole classification, pothole severity, pothole visibility, pothole difficulty to avoid, pothole event occurrence rate.

4. The system of claim 1, wherein the pothole detector is further configured to provide pothole data.

5. The system of claim 1, wherein a pothole definition depends on a vehicle weight or vehicle type.

6. The system of claim 1, wherein a pothole definition depends on a vehicle speed.

7. The system of claim 1, further comprising a vehicle data server.

8. The system of claim 7, wherein the vehicle data server is configured to receive pothole data from the vehicle event recorder.

9. The system of claim 7, wherein the vehicle data server is configured to transmit pothole data to pothole authorities.

10. The system of claim 7, wherein the vehicle data server is further configured to provide the pothole video for playing.

11. The system of claim 10, wherein providing the pothole video comprises selecting the pothole video.

12. The system of claim 10, wherein selecting the pothole video comprises selecting the pothole video with a dramatic video associated pothole collision severity for a pothole location.

13. The system of claim 10, wherein selecting the pothole video comprises selecting the pothole video with a dramatic video associated pothole collision severity for a given vehicle type.

14. The system of claim 7, wherein the vehicle data server is further configured to delete pothole data.

15. The system of claim 14, wherein the vehicle data server is configured to delete pothole data in the event a pothole frequency is equal to zero.

16. The system of claim 14, wherein the vehicle data server is configured to delete pothole data in the event a manual indication of a pothole removal is received.

17. The system of claim 7, wherein the vehicle data server is further configured to build a pothole map.

18. The system of claim 1, wherein determining the pothole uses model trained on previously stored pothole data and confirmation of pothole data.

19. A method for pothole detection, comprising:

receiving sensor data;

determining, using a pothole detector, a pothole based at least in part on the sensor data using a model, wherein the model is used to classify sensor data; and

storing pothole data associated with the pothole, wherein pothole data comprises a pothole video.

20. A computer program product for pothole detection, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving sensor data;

determining, using a pothole detector, a pothole based at least in part on the sensor data using a model, wherein the model is used to classify sensor data; and

storing pothole data associated with the pothole, wherein the pothole data comprises a pothole video.
