Abstract

Un dispositivo de inspección de superficie de acuerdo con la presente invención incluye: dos o más fuentes de luz lineales oblicuas que emiten haces de luz de iluminación oblicua sobre una región objetivo de inspección de material de acero; uno o más sensores lineales que reciben cada uno de los haces de luz reflejada de los haces de luz de iluminación oblicua de las fuentes de luz lineales oblicuas respectivas, los haces de luz reflejada siendo de la región objetivo de inspección para cada fuente de luz lineal oblicua, y capturar imágenes; y una unidad de detección que detecta un defecto de superficie lineal en la región objetivo de inspección usando imágenes capturadas por uno o más sensores lineales. Las proyecciones ortográficas de al menos dos haces de luz de iluminación oblicua fuera de los haces de luz de iluminación oblicua desde las dos o más fuentes de luz lineales oblicuas sobre una superficie del material de acero son ortogonales entre sí en la región objetivo de inspección.
