Abstract

Este dispositivo de detección de objeto tridimensional se caracteriza por estar dotado con: una unidad (10) de captura de imagen para la captura de un área predeterminada hacia atrás de un vehículo principal; una unidad (31) de conversión de imágenes para convertir el punto de vista de una imagen capturada para crear una imagen a vista de ojo de pájaro; una unidad (32,33) de detección de objetos tridimensionales la generación de información de diferencia de forma de onda contando un número de píxeles que indican una diferencia que tienen un predeterminado primer valor umbral o mayor en una diferencia de imagen, de las imágenes a vista de ojo de pájaro alineadas para formar una distribución de frecuencias, y la detección de un objeto en tres dimensiones presentes en un carril adyacente sobre la base de la información de una forma de onda cuando la diferencia de información de forma de onda está en un segundo valor umbral predeterminado o mayor; y unos medios (34) de detección de fuente de luz para detectar una fuente de luz presente hacia atrás del vehículo principal, la unidad (34) de detección de objetos en tres dimensiones estableciendo el primer valor umbral o el segundo valor umbral más alto de manera que el objeto tridimensional es difícil de detectar en una área hacia adelante más hacia delante que una línea que conecta la fuente de luz y la unidad (10) imagen que captura cuando se ha detectado la fuente de luz.
