Methods and systems for detecting weather conditions including wet surfaces using vehicle onboard sensors
First Claim
1. A method comprising:
- receiving laser data collected for an environment of a vehicle, wherein the laser data includes a plurality of laser data points;
receiving radar data collected for the environment of the vehicle, wherein the radar data is indicative of a presence of one or more tracked objects in the environment of the vehicle;
determining, by a computing device, laser data points of the plurality of laser data points that are associated with the one or more tracked objects in the environment indicated by the radar data;
determining, by the computing device, laser data points of the plurality of laser data points that are unassociated with the one or more tracked objects in the environment indicated by radar data; and
identifying by the computing device an indication that a surface on which the vehicle travels is wet based at least on the determining that the laser data points that are unassociated with the one or more tracked objects in the environment indicated by the radar data.

Abstract
Example methods and systems for detecting weather conditions including wet surfaces using vehicle onboard sensors are provided. An example method includes receiving laser data collected for an environment of a vehicle. The method also includes determining laser data points that are associated with one or more objects in the environment, and based on laser data points being unassociated with the one or more objects in the environment, identifying an indication that a surface on which the vehicle travels is wet. The method may further include receiving radar data collected for the environment of the vehicle that is indicative of a presence of the one or more objects in the environment of the vehicle, and identifying the indication that the surface on which the vehicle travels is wet further based on laser data points being unassociated with the one or more objects in the environment indicated by the radar data.

15. A non-transitory computer readable storage medium having stored therein instructions, that when executed by a computing device, cause the computing device to perform functions comprising:
-
receiving laser data collected for an environment of a vehicle, wherein the laser data includes a plurality of laser data points; receiving radar data collected for the environment of the vehicle, wherein the radar data is indicative of a presence of one or more tracked objects in the environment of the vehicle; determining laser data points of the plurality of laser data points that are associated with the one or more tracked objects in the environment indicated by the radar data; determining laser data points of the plurality of laser data points that are unassociated with the one or more tracked objects in the environment indicated by the radar data; and identifying an indication that a surface on which the vehicle travels is wet based at least on the determining that the laser data points that are unassociated with the one or more tracked objects in the environment indicated by the radar data; based on the indication that the surface on which the vehicle travels is wet, determining a driving decision for the vehicle; and providing instructions to the vehicle of the determined driving decision. - View Dependent Claims (16)

17. A system, comprising:
-
at least one processor; and data storage comprising instructions executable by the at least one processor to cause the system to perform functions comprising; receiving laser data collected for an environment of a vehicle, wherein the laser data includes a plurality of laser data points; receiving radar data collected for the environment of the vehicle, wherein the radar data is indicative of a presence of one or more tracked objects in the environment of the vehicle; determining laser data points of the plurality of laser data points that are associated with the one or more tracked objects in the environment indicated by the radar data; determining laser data points of the plurality of laser data points that are unassociated with the one or more tracked objects in the environment indicated by the radar data; and identifying by the computing device an indication that a surface on which the vehicle travels is wet based at least on the determining that the laser data points that are unassociated with the one or more tracked objects in the environment indicated by the radar data; based on the indication that the surface on which the vehicle travels is wet, determining a driving decision for the vehicle; and providing instructions to the vehicle of the determined driving decision. - View Dependent Claims (18)
