Abstract:
A traffic light recognition device includes: an imaging attitude setting unit configured to set an imaging direction of the camera on the basis of a position on the image of the traffic light and of a moving direction in the future on the image of the traffic light; a camera attitude controller configured to change the imaging direction of the camera to an imaging direction set by an imaging direction setting unit; and a traffic light recognition unit configured to recognize the traffic light from an image captured in the imaging direction by the camera. The traffic light recognition device is capable of accurately detecting the lighting state of a traffic light without being affected by the attitude of a camera.

Claim (Index 9):
A traffic light recognition method, comprising the steps of:\n capturing, by an imaging unit, an image around a vehicle; acquiring map information around the vehicle; detecting a current position on a map of the vehicle; estimating a position on an image of a traffic light on a basis of the current position and the map information; setting an imaging direction of the imaging unit on a basis of the position on the image of the traffic light and of a moving direction in the future on the image of the traffic light; changing the imaging direction of the imaging unit to a set imaging direction; recognizing the traffic light from an image captured in the imaging direction by the imaging unit; setting a change point or region at which the imaging direction of the imaging unit is changed, on a basis of the position on the image of the traffic light and of the moving direction in the future on the image of the traffic light; and changing the imaging direction of the imaging unit when the vehicle reaches the change point or region.
