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 1):
A traffic light recognition device, comprising:\n an imaging unit mounted on a vehicle and configured to capture an image around the vehicle; a map information acquisition unit configured to acquire map information around the vehicle; a vehicle current position detector configured to detect a current position on a map of the vehicle; a traffic light position estimator configured to estimate a position on an image of a traffic light on a basis of the current position and the map information; an imaging direction setting unit configured to set 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; an imaging direction change unit configured to change the imaging direction of the imaging unit to an imaging direction set by the 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 imaging unit, wherein the imaging direction change unit sets a change point or region at which the imaging direction change unit changes the imaging direction of the imaging unit, 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 the imaging direction change unit changes the imaging direction when the vehicle reaches the change point or region.
