位置検出方法及び位置検出装置
Document Type and Number:
Japanese Patent JP7119970
Kind Code:
B2
Abstract:
Provided is a position detecting method for detecting a winding position of a reinforced fiber impregnated with resin when a plurality of hoop layers is formed in a cylindrical portion of a liner. The position detecting method includes: an imaging step of taking, by an imaging portion, a captured image of the reinforced fiber just after the reinforced fiber is wound around a hoop layer illuminated with oblique light by a lighting assembly, the imaging portion having an optical axis set at the same angle as an optical axis of the lighting assembly around a central axis of the liner; and a detecting step of detecting the winding position of the reinforced fiber based on the number of high intensity pixels or the number of low intensity pixels in each pixel column arranged in an axial direction of the liner in the binarized captured image.
