Abstract
The technology relates to controlling a vehicle based on a railroad light's activation status. In one example, one or more processors receive images of a railroad light. The one or more processors determine, based on the images of the railroad light, the illumination status of a pair of lights of the railroad light over a period of time as the vehicle approaches the railroad light. The one or more processors determine based on the illumination status of the pair of lights, a confidence level, wherein the confidence level indicates the likelihood the railroad light is active. The vehicle is controlled as it approaches the railroad light based on the confidence level.
Claims20
A computing device comprising:
- one or more processors, wherein the one or more processors are configured to:
- receive images of a pair of lights of a railroad light assembly;
- modify, based on one or more illumination patterns of the pair of lights of the railroad light assembly in the received images, a confidence level that indicates a likelihood that the railroad light assembly is active;
- and
- control a vehicle to autonomously take an action based on the modified confidence level.
A system comprising:
- one or more sensors configured to capture images of a pair of lights of a railroad light assembly;
- and
- a computing device including one or more processors, wherein the one or more processors are configured to:
- receive the images of the pair of lights of the railroad light assembly from the one or more sensors;
- modify, based on one or more illumination patterns of the pair of lights of the railroad light assembly in the received images, a confidence level that indicates a likelihood that the railroad light assembly is active;
- and
- control a vehicle to autonomously take an action based on the modified confidence level.
