Abstract
A method and system may determine a location of a vehicle, collect an image using a camera associated with the vehicle, analyze the image in conjunction with the location of the vehicle and/or previously collected information on the location of traffic signals or other objects (e.g., traffic signs), and using this analysis locate an image of a traffic signal within the collected image. The position (e.g., a geographic position) of the signal may be determined, and stored for later use. The identification of the signal may be used to provide an output such as the status of the signal, such as green light.
