Abstract

Un dispositivo de inspección es un dispositivo que inspecciona la apariencia de un objetivo, que incluye: un dispositivo de imágenes configurado para generar imágenes del objetivo desde una primera dirección; una unidad de iluminación configurada para aplicar luz al objetivo en un primer patrón de iluminación en el cual la luz se aplica al objetivo desde una primera posición y en un segundo patrón de iluminación en el cual la luz se aplica al objetivo desde una segunda posición diferente a la primera posición; y un controlador configurado para adquirir una primera imagen de inspección al provocar que el dispositivo de imágenes genere una imagen del objetivo al cual se aplica la luz en el primer patrón de iluminación, el controlador estando configurado para adquirir una segunda imagen de inspección al provocar que el dispositivo de imágenes genere una imagen del objetivo al cual se aplica la luz en el segundo patrón de iluminación, el controlador estando configurado para inspeccionar una apariencia del objetivo con base en la primera imagen de inspección, la segunda imagen de inspección, y una imagen de referencia proporcionada de antemano. La primera posición y la segunda posición se superponen entre sí cuando se ven desde la primera dirección.
