Abstract

Un dispositivo de reconocimiento de semáforo incluye: una cámara (11) que captura una imagen alrededor de un vehículo; una unidad (17) de adquisición de información de mapa configurada para adquirir la información de mapa alrededor del vehículo; un detector (12) de la posición actual del vehículo configurado para detectar una posición actual en un mapa del vehículo; y un estimador (21) de la posición del semáforo configurado para estimar una posición en el mapa del semáforo con base en la posición actual y la información de mapa. El dispositivo de reconocimiento de semáforo adicionalmente incluye: una unidad (23) de establecimiento de la actitud de obtención de imágenes configurada para establecer una dirección de obtención de imágenes de la cámara con base en una posición en la imagen del semáforo y en una dirección de movimiento en el futuro en la imagen del semáforo; un controlador (24) de la actitud de la cámara configurado para cambiar la dirección de obtención de imágenes de la cámara a una dirección de obtención de imágenes establecida por una unidad de establecimiento de la dirección de obtención de imágenes; y una unidad (14) de reconocimiento de semáforo configurada para reconocer el semáforo a partir de una imagen capturada en la dirección de obtención de imágenes por la cámara. El dispositivo de reconocimiento de semáforo es capaz de detectar con precisión el estado de iluminación de un semáforo sin ser afectado por la actitud de una cámara.
