Abstract
A method of detecting and identifying road surface defects is provided. Motion and position information is received from a plurality of vehicles. A profile is retrieved for a particular vehicle from a database of vehicle profiles by using an identifier of the particular vehicle. One or more criteria are identified for detecting a particular type of road surface defect based on the retrieved profile of the particular vehicle. Upon determining that the received motion and position data satisfies the identified criteria, a detection of a road surface defect of the particular type and a location associated with the detected road surface defect based on the received position information is reported.
Claims20
A computer implemented method of determining road surface defects, comprising:
- receiving motion, position, and stability control system information from a plurality of vehicles by a data center;
- retrieving a profile for a hypothetical normal vehicle from a database of vehicle profiles by the data center;
- identifying one or more criteria for detecting a particular type of road surface defect from different types of road surface defects based on the retrieved profile of the hypothetical normal vehicle, by the data center;
- retrieving, by the data center, video information from a vehicle of the plurality of vehicles only upon determining that the motion and received position and stability control system information satisfies the identified criteria, thereby reducing an amount of video data received and stored by the data center;
- and
- upon determining by the data center that the motion and received position and stability control system information satisfies the identified criteria, reporting a detection of a road surface defect of the particular type as well as a video of the road surface defect based on the video data and a location associated with the detected road surface defect based on the received position information.
A computing device comprising:
- a processor at a data center;
- a network interface coupled to the processor;
- a storage device storing a set of instructions, wherein an execution of the set of instructions by the processor configures the computing device to perform acts comprising:
- collecting data from a set of sensors of a vehicle;
- retrieving a profile for a hypothetical normal vehicle;
- identifying one or more criteria for detecting a particular type of road surface defect from different types of road surface defects based on the retrieved profile of the hypothetical normal vehicle;
- the data center retrieving video information from a vehicle of the plurality of vehicles only upon determining that the motion and received position and stability control system information satisfies the identified criteria, thereby reducing an amount of video data received and stored by the data center;
- and
- upon determining by the data center that the collected sensor data satisfies identified criteria, reporting a detection of a road surface defect of the particular type as well as a video of the road surface defect based on the video data and a location associated with the detected road surface defect, based on the received position information.
