Abstract
To reliably and efficiently make foreign matters adhered onto a green tire formed by a strip winding method. It comprises a raw data acquiring step Sa in which raw three-dimensional data Dabout an examination surfaceare created through rotation of a green tire T and through irradiation with sensor lightL in an X direction by a two-dimensional displacement sensor; an averaging processing step Sb in which processed three-dimensional data Dare obtained by averaging processing the raw three-dimensional data D; and an imaging step Sc in which the distance data z in the processed three-dimensional data Dare each binarized, and an image is created from the binarized processed three-dimensional data D. The widths Wx and Wy of a range K of the averaging process are set to be greater than a spiral pitch P of a rubber strip G and less than a width Gw of the rubber strip G.
