摘要： A traffic light detection device uses an image pickup unit mounted on a vehicle to extract, from an image taken of surroundings of the vehicle, synchronized pixels (DA1 to DA3), whose brightness changes in synchronization with an alternating current period of electric power supplied to a traffic light, and detects the traffic light from the synchronized pixels. The traffic light detection device is provided with: a positional variation calculation unit that calculates positional variation amounts (G1 to G3, g1 to g3) of continuously extracted positions of the synchronized pixels; and a signal lamp determination unit that determines, as a signal lamp candidate, the synchronized pixels whose positional variation amount is equal to or smaller than a threshold value.

摘要： A traffic light recognition device includes: a camera (11) that captures an image around a vehicle; a map information acquisition unit (17) configured to acquire map information around the vehicle; a vehicle current position detector (12) configured to detect a current position on a map of the vehicle; and a traffic light position estimator (21) configured to estimate a position on the map of the traffic light on the basis of the current position and the map information. The traffic light recognition device further includes: an imaging attitude setting unit (23) 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 (24) 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 (14) 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.

摘要： A traffic signal detection device includes a narrow-angle camera 11, a wide-angle camera 12 having an angle of view wider than the narrow-angle camera 11, and a traffic signal detector 4 configured to detect a traffic signal from at least any of a narrow-angle image captured by the narrow-angle camera 11 and a wide-angle image captured by the wide-angle camera 12. The traffic signal detector 4 selects, as a detection result, any of a traffic signal detected from the narrow-angle image and a traffic signal detected from the wide-angle image, on the basis of a deceleration start region in which a vehicle 5 should start deceleration, the deceleration start region calculated from a position of a traffic signal with respect to the vehicle 5 and a speed of the vehicle 5 in order to stop the vehicle 5 at a stop position with respect to the traffic signal.
