Abstract
(EN)
Provided are a round steel material marking detection device and detection method, and a method for manufacturing a steel material, with which the risk of a marking being missed is significantly reduced by detecting markings automatically. A round steel material marking detection device (1) detects a marking (M) that has been applied at the position of a surface flaw on a round steel material (S). The marking detection device (1) is provided with: an image capturing device (3) which captures images of a prescribed position (P) in the circumferential direction on the surface of the round steel material (S), which is rotating in a circumferential direction, with a prescribed period and with a resolution smaller than the dimension of the marking (M) being a measurement target; an image processing unit (8) which processes an image obtained by joining, in the circumferential direction, the images of the prescribed position (P) captured by the image capturing device (3); and a marking extraction unit (9) which extracts the marking (M) from the image that has been subjected to image processing by the image processing unit (8).

L'invention concerne un dispositif de détection et un procédé de détection de marquage de matériau en acier rond, et un procédé de fabrication d'un matériau en acier, avec lesquels le risque de rater un marquage est considérablement réduit par la détection automatique des marquages. Un dispositif de détection de marquage de matériau en acier rond (1) détecte un marquage (M) qui a été appliqué à la position d'un défaut de surface sur un matériau en acier rond (S). Le dispositif de détection de marquage (1) comporte : un dispositif de capture d'image (3) qui capture des images d'une position prescrite (P) dans la direction circonférentielle sur la surface du matériau en acier rond (S), qui tourne dans une direction circonférentielle, avec une période prescrite et avec une résolution inférieure à la dimension du marquage (M) qui est une cible de mesure ; une unité de traitement d'image (8) qui traite une image obtenue en assemblant, dans la direction circonférentielle, les images de la position prescrite (P) capturées par le dispositif de capture d'image (3) ; et une unité d'extraction de marquage (9) qui extrait le marquage (M) de l'image qui a été soumise à un traitement d'image par l'unité de traitement d'image (8).
