Abstract
Provided are a steel-shape measurement device and a steel-shape correction device. The steel-shape measurement device measures a distance to a detection spot group on a to-be-scanned surface of a steel product with a laser rangefinderA that measures the distance through scanning of a steel product S with a laser beam emitted from one laser light sourceand redirected with a galvanometer mirrorand measures a shape of the steel product from obtained measured-distance data. The steel-shape measurement device includes an object having a 45°-0° diffuse reflectance of equal to or lower than 10% as a laser-beam absorberat least one portion within an irradiation range irradiated with a regular-reflected laser beam from a to-be-scanned surface of the steel product.
