SYSTÈME ENDOSCOPIQUE AVEC DES MOYENS POUR VISUALISER UNE CIBLE TOURNANTE ET AVEC UNE UNITÉ POUR LA RECONSTRUCTION DE DONNÉES D'IMAGE ET UN PROCÉDÉ D'IMAGERIE ASSOCIÉ

摘要

An endoscope system 1 includes a borescope 11A configured to pick up images of a rotatable inspection target with a linear sensor 23a at predetermined time intervals ”TI to acquire a plurality of first inspection target images along a direction B0 perpendicular to a rotating direction of the inspection target, a borescope 11B configured to pick up images of the inspection target with a linear sensor 26a at the predetermined time intervals ”TI in synchronization with the acquisition timing of the first inspection target images to acquire a plurality of second inspection target images along the rotating direction of the inspection target, and a PC 12. The PC 12 reconstructs image data on each of the plurality of first inspection target images based on time-series image information formed of the second inspection target images arranged over time and a correction table CT containing a position of a pixel EP including a predetermined feature quantity in each of the second inspection target images and an amount of an angle of rotation of the inspection target.
