Abstract

Se proporciona un método de inspección para una superficie de un cuerpo cerámico capaz de determinar cualquier grieta de manera más fiable que la realizada convencionalmente. El método incluye una etapa de captura de imágenes en la que se lleva a cabo una captura de imágenes de una región iluminada de una superficie de inspección que está siendo iluminada con al menos una de primera y segunda luces de iluminación emitidas a una superficie de inspección desde direcciones mutuamente diferentes emparedando un medio de captura de imágenes, una etapa de generación de imágenes de determinación para generar una imagen de determinación con base en un resultado de captura de imágenes, y una etapa de determinación en la que se lleva a cabo una determinación con base en la imagen de determinación. Cuando se genera una primera imagen de determinación con base en un primer resultado de captura de imágenes obtenido bajo iluminación al menos con la primera luz de iluminación, y una segunda imagen de determinación se genera con base en un segundo resultado de captura de imágenes bajo iluminación al menos con la segunda luz de iluminación, la primera y segunda imágenes de determinación se generan de manera que la determinación de la presencia o ausencia de cualquier grieta se pueda llevar a cabo con base en una diferencia entre modos de formación de regiones de sombra en la primera y segunda imágenes de determinación cuando la primera y segunda imágenes de determinación se comparan entre sí.
