Abstract

La presente invención clasifica, con alta precisión, una pluralidad de tipos de defectos superficiales en los cuales se produce fácilmente una variación, sin depender de información tal como el área o forma de los defectos superficiales. La luz de reflexión desde un sitio a ser la imagen capturada en una placa de acero 2 es la imagen capturada simultáneamente mediante una unidad de captura de imagen de luz de reflexión regular 4 y una unidad de captura de imagen de luz de reflexión difusa 5. Una unidad de procesamiento de señales de imagen 6, a partir de una señal de imagen de reflexión regular se obtiene T1 a través de la captura de imagen realizada por la unidad de captura de imágenes de luz de reflexión regular 4, un sitio que tiene una luminancia por debajo de un umbral prescrito como sitio de defecto superficial. Se lleva a cabo un procesamiento de umbral sobre una señal de imagen de reflexión difusa T2 obtenida a través de la captura de imagen realizada por la unidad de captura de imágenes de luz de reflexión difusa 5 en relación con un sitio correspondiente al sitio de defecto superficial extraído, mediante lo cual se clasifica el tipo de defecto en el sitio del+ defecto superficial extraído.
