Methods and Systems for Detecting Weather Conditions Including Fog Using Vehicle Onboard Sensors
First Claim
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;
associating, by a computing device, 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; 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.
