Abstract

La presente invención se provee con: un medio (32, 33) de detección de objeto tridimensional que genera información de la forma de onda de diferencia con base en el número de pixeles que tienen una diferencia igual a o mayor que un primer valor de umbral en una imagen de diferencia en la cual se alinean las imágenes de vista aérea tomadas en diferentes tiempos, y detecta un objeto tridimensional con base en la información de la forma de onda de diferencia cuando la información de la forma de onda de diferencia dentro de un marco de detección predeterminado es igual a o mayor que un segundo valor de umbral; un medio (35) de detección de fuente de iluminación que detecta una fuente de iluminación; un medio (34) de determinación de certeza que determina la certeza con la cual una fuente de iluminación es el faro delantero de otro vehículo que viaja en el carril siguiente al adyacente; y un medio (35) de control que, si la certeza es igual a o mayor que un valor predeterminado, establece el primer valor de umbral o el segundo valor de umbral tal que un objeto tridimensional sea más difícil de detectar en un área delantera más hacia adelante que una línea que conecta la fuente de iluminación y un medio (10) de formación de imágenes en el marco de detección, y, si la certeza es menor que el valor predeterminado, establece el primer valor de umbral o el segundo valor de umbral tal que un objeto tridimensional sea progresivamente más difícil de detectar hacia el extremo frontal o el extremo trasero desde el centro del marco de detección.
