Title:
CIRCUMFERENTIAL MAIN GROOVE DETECTION METHOD AND CIRCUMFERENTIAL MAIN GROOVE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/202632
Kind Code:
A1
Abstract:
A circumferential main groove detection method for detecting a position of a circumferential main groove of a tire from 3D data of a tread surface of the tire using a computer includes: a cross section data extraction step of extracting cross section data of the tread surface in a direction inclined with respect to a tire circumferential direction at a plurality of sections in the tire circumferential direction; a region dividing step of dividing the cross section data into a plurality of regions in the direction; an evaluation step of evaluating ridges and grooves within each region in a relative manner; and a circumferential main groove identifying step of adding together evaluation results of the divided regions for an identical position in the tire circumferential direction and identifying a position of a circumferential main groove of the tire.
