1. A method comprising:
- receiving laser data collected from scans of an environment of a vehicle, wherein the laser data includes a plurality of laser data points;
determining, by a computing device, laser data points of the plurality of laser data points that are associated with one or more tracked objects in the environment;
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;
comparing the laser data points that are unassociated with the one or more tracked objects in the environment with stored laser data points representative of a pattern due to fog; and
based on the comparison, identifying by the computing device an indication that a weather condition of the environment of the vehicle includes fog.

Abstract
Methods and systems for detecting weather conditions including fog using vehicle onboard sensors are provided. An example method includes receiving laser data collected from scans of an environment of a vehicle, and associating, by a computing device, laser data points of with one or more objects in the environment. The method also includes comparing laser data points that are unassociated with the one or more objects in the environment with stored laser data points representative of a pattern due to fog, and based on the comparison, identifying by the computing device an indication that a weather condition of the environment of the vehicle includes fog.

13. A method comprising:
-
receiving laser data collected from scans of 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 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 objects in the environment indicated by the radar data; and based on laser data points being unassociated with the one or more objects in the environment indicated by the radar data, identifying by the computing device an indication that a weather condition of the environment of the vehicle includes fog. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system, comprising:
-
at least one processor; and non-transitory data storage comprising instructions executable by the at least one processor to cause the system to perform functions comprising; receiving laser data collected from scans of an environment of a vehicle, wherein the laser data includes a plurality of laser data points; associating laser data points of the plurality of laser data points with one or more objects in the environment; comparing laser data points that are unassociated with the one or more objects in the environment with stored laser data points representative of a pattern due to fog; based on the comparison, identifying by the computing device an indication that a weather condition of the environment of the vehicle includes fog; receiving radar data collected for the environment of the vehicle, wherein the radar data is indicative of a presence of one or more objects in the environment of the vehicle; determining an object in the environment indicated by the radar data that is unassociated with the laser data points; determining a distance between the object in the environment indicated by the radar data unassociated with laser data points and a given object of the one or more objects in the environment indicated by the radar data and associated with laser data points; and determining an estimation of a density of the fog based on the distance. - View Dependent Claims (20)
