SYSTEMS AND METHODS FOR DETERMINING THE STATUS OF A TURN LANE TRAFFIC LIGHT

摘要

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a traffic light detection system is provided for a vehicle. One or more processing devices associated with the system receive at least one image of an area forward of the vehicle via a data interface, with the area including at least one traffic lamp fixture having at least one traffic light. The processing device(s) determine, based on at least one indicator of vehicle position, whether the vehicle is in a turn lane. Also, the processing device(s) process the received image(s) to determine the status of the traffic light, including whether the traffic light includes an arrow. Further, the system may cause a system response based on the determination of the status of the traffic light, whether the traffic light includes an arrow, and whether the vehicle is in a turn lane.

主权项

1. A traffic light detection system for a vehicle, the system comprising:
at least one image capture device configured to acquire at least one image of an area forward of the vehicle, the area including a traffic lamp fixture having at least one traffic light; a data interface; and at least one processing device configured to:
receive the at least one acquired image via the data interface;determine, based on at least one indicator of vehicle position, whether the vehicle is in a turn lane;perform image processing on the at least one image to determine whether an arrow exists in the at least one image within pixels of the image representative of the traffic light;determine, based on the at least one image, a status of the traffic light; andcause a system response based on the determination of the status of the traffic light, whether the traffic light includes an arrow, and whether the vehicle is in a turn lane.
