1. A driver-assist system for a vehicle, the system comprising:
- a first image capture device configured to acquire a first plurality of images of an area forward of the vehicle, wherein the first image capture device has a first angular field of view;
a second image capture device configured to acquire a second plurality of images of an area forward of the vehicle, wherein the second image capture device has a second angular field of view greater than the first angular field of view, the second angular field of view having at least a portion overlapping with the first angular field of view;
a third image capture device configured to acquire a third plurality of images of an area forward of the vehicle, wherein the third image capture device has a third angular field of view greater than the second angular field of view, the third angular field of view having at least a portion overlapping with the first angular field of view and with the second angular field of view;
a data interface; and
at least one processing device configured to;
receive, via the data interface, the first, second, and third plurality of images;
analyze two or more images of the first, second, and third plurality of images to detect a feature associated with an environment of the vehicle and track a position of the detected feature relative to the vehicle; and
transmit a control signal generated in response to the detected and tracked feature to at least one of a plurality of vehicle control systems to cause the vehicle to take at least one navigational response based on image information derived from any two of the first, second, and third plurality of images.

Abstract
Systems and methods use cameras to provide autonomous navigation features. In one implementation, a driver-assist system is provided for a vehicle. The system may include one or more image capture devices configured to acquire images of an area forward of the vehicle. The system may also include at least one processing device configured to receive, via one or more data interfaces, the images. The at least one processing device may be further configured to analyze the images acquired by the one or more image capture devices and cause at least one navigational response in the vehicle based on monocular and/or stereo image analysis of the images.
