Abstract: A system comprising at least one hardware processor for updating a cloud-based road anomaly database is disclosed, wherein the system receives information from a vehicle regarding an object detected by one or more sensors of the vehicle, the information may include a location and/or a size of the detected object; compares the location and/or the size of the first detected object against data stored in a road feature database regarding the first detected object; determines, based on comparing the location and/or the size, an accuracy score associated with the first detected object and the second detected object; and updates the cloud-based road anomaly database with the received information for the second detected object based on the associated accuracy score being higher than at least one of a threshold accuracy score or an accuracy score associated with corresponding object information stored in the cloud-based road anomaly database.

Abstract: In some examples, a system may receive, from at least one camera of a vehicle, at least one image including a road. The system may further receive vehicle location information including an indication of a location of the vehicle. In addition, the system may receive at least one of historical information from a historical database, or road anomaly information, where the road anomaly information is determined from at least one of a road anomaly database or real-time road anomaly detection. Based on the at least one image, the indication of the location of the vehicle, and the at least one of the historical information or the road anomaly information, the system may generate at least one of a disparity map or a disparity image.

Abstract: A system for dynamic image compression in autonomous vehicles with multiple cameras. The cameras of a vehicle may be prioritized based on various features, and different image compression techniques may be assigned to different cameras in the vehicle, based on the priorities of the cameras, to reduce overall processing load of the vehicle.

Abstract: In some examples, a service computing device receives, from a vehicle computing device onboard a vehicle, a communication including sensor data obtained from at least one sensor onboard the vehicle. Based on the communication, the service computing device determines a transmission delay corresponding to a difference between a time when the vehicle sent the communication and a time when the communication was received. Based on the communication, the service computing device determines a trajectory of the vehicle on a travel route. Based on the sensor data, transmission delay, wind direction and magnitude, surrounding objects, and trajectory, the service computing device determines vehicle control information for the vehicle. The service computing device sends, to the vehicle, based at least on the vehicle control information, at least one instruction causing the vehicle to perform at least one control operation for traversing one or more locations associated with the trajectory of the vehicle.
