TIRE ANALYSIS SYSTEM AND ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tire analysis system enabling highly accurate analysis, and an analysis method.SOLUTION: An analysis method includes: a step ST2 of photographing an image at the time when a plurality of grating patterns engraved on a tire are respectively at predetermined positions; a step ST7 of calculating a space coordinate of the grating pattern by performing shape analysis with a photographed image; a step of detecting variation of the arrangement of the grating pattern on the basis of the space coordinate; and a step ST8 of correcting the arrangement of the grating pattern on the basis of the variation.
