Abstract

El dispositivo de detección de objetos tridimensionales cuenta con: una unidad (32, 33, 34) de detección de objetos tridimensionales para generar la información de la forma de onda de la diferencia al contar el número de pixeles que indican una diferencia en un valor de umbral predeterminado o superior en una imagen de diferencia en la cual, las imágenes de vista a ojo de pájaro en diferentes momentos han sido alineadas, y detectar un objetos tridimensionales con base en la información de la forma de onda de la diferencia; una unidad (35) de establecimiento del área de referencia de la imagen para establecer, como el área de referencia de la imagen, un área que es diferente del área de detección y en la cual, se predice la extracción de la información del contorno de un objeto; una unidad (35) de detección de la información del contorno para extraer la información del contorno del objeto; una unidad (35) de cálculo de la nitidez de referencia, para calcular la nitidez de referencia con base en la información del contorno detectada en el área de referencia de la imagen; y una unidad (35) de cálculo de la nitidez del objeto, para calcular la nitidez del objeto con base en la información del contorno detectada en el área de detección. La unidad (32, 33, 34) de detección de objetos tridimensionales calcula una nitidez final con base en la nitidez de referencia y la nitidez del objeto, y establece el valor de umbral de la diferencia con base en la nitidez final calculada.
