Abstract

Se proporciona un dispositivo (1) de detección de objetos tridimensionales con una cámara (10) y una computadora (20). La computadora (20) somete una imagen capturada por la cámara (10) a un proceso de conversión del punto de vista para crear una imagen de vista aérea, se calcula la diferencia de brillo entre los dos pixeles cercanos a cada posición de una pluralidad de posiciones a lo largo de una línea vertical virtual extendida en la dirección vertical en el espacio real, y se detecta un objeto tridimensional en la base de la continuidad de la diferencia de brillo calculada en cada posición.
