Systems and methods for detecting traffic lights

A method for navigating a host vehicle, the method comprising:

• receiving at least a first captured image acquired by a first camera associated with the host vehicle, the first captured image being representative of an environment of the host vehicle;
• receiving at least a second captured image acquired by a second camera associated with the host vehicle, the second captured image being representative of the environment of the host vehicle, wherein a field of view of the first camera at least partially overlaps with a field of view of the second camera, wherein the first captured image includes a representation of a traffic light in the environment of the host vehicle, wherein the second captured image also includes a representation of the traffic light, and wherein the second camera is configured to operate in at least:
• a primary mode in which at least one operational parameter of the second camera is tuned for detecting at least one feature of the traffic light, the at least one operational parameter being tuned based on at least one characteristic of the traffic light detected in the first captured image or the second captured image, and
• a secondary mode different from the primary mode, wherein the second camera is configured to selectively switch from the secondary mode to the primary mode based on a determination that the host vehicle is approaching the traffic light;
• analyzing the second captured image captured using the primary mode to detect the at least one feature of the traffic light;
• and
• causing at least one navigational action by the host vehicle based on the detected at least one feature of the traffic light.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, are configured to cause at least one processor to perform a method for navigating a host vehicle, the method comprising:

• receiving at least a first captured image acquired by a first camera associated with the host vehicle, the first captured image being representative of an environment of the host vehicle;
• receiving at least a second captured image acquired by a second camera associated with the host vehicle, the second captured image being representative of the environment of the host vehicle, wherein a field of view of the first camera at least partially overlaps with a field of view of the second camera, wherein the first captured image includes a representation of a traffic light in the environment of the host vehicle, wherein the second captured image also includes a representation of the traffic light, and wherein the second camera is configured to operate in at least:
• a primary mode in which at least one operational parameter of the second camera is tuned for detecting at least one feature of the traffic light, the at least one operational parameter being tuned based on at least one characteristic of the traffic light detected in the first captured image or the second captured image, and
• a secondary mode different from the primary mode, wherein the second camera is configured to selectively switch from the secondary mode to the primary mode based on a determination that the host vehicle is approaching the traffic light;
• analyzing the second captured image captured using the primary mode to detect the at least one feature of the traffic light;
• and
• causing at least one navigational action by the host vehicle based on analysis of the representation of the traffic light in the at least a first captured image and based on analysis of the representation of the traffic light in the at least a second captured image.
