Systems and methods for detecting traffic lights
First Claim
1. A traffic light detection system for a vehicle, the system comprising:
- at least one image capture device configured to acquire a plurality of images of a traffic light, wherein the traffic light is located in a region above the vehicle and outside of a sightline of a typical driver location in the vehicle;
a data interface; and
at least one processing device configured to;
receive the plurality of images via the data interface;
determine a status of the traffic light based on analysis of at least a first image from among the plurality of images;
determine a change in status of the traffic light based on at least a second image from among the plurality of images; and
cause a system response based on the determination of the change in status.

Abstract
Systems and methods use cameras to provide autonomous navigation features. In one implementation, a system includes at least one image capture device configured to acquire a plurality of images of a traffic light located in a region above the vehicle, outside of a sightline of a typical driver location in the vehicle. The system further includes a data interface, and at least one processing device. The at least one processing device may be configured to receive the plurality of images via the data interface, determine a status of the traffic light based on analysis of at least a first image from among the plurality of images, determine a change in status of the traffic light based on at least a second image from among the plurality of images, and cause a system response based on the determination of the change in status.

20. A method for navigating a vehicle, the method comprising:
-
acquiring, via at least one image capture device, a plurality of images of a traffic light, wherein the traffic light is located in a region above the vehicle and outside of a sightline of a typical driver location in vehicle; determining a status of the traffic light based on analysis of at least a first image from among the plurality of images; determining a change in status of the traffic light based on at least a second image from among the plurality of images; and causing a system response based on the determination of the change in status.
