Title:
DATA PROCESSING METHOD AND DATA PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/083442
Kind Code:
A1
Abstract:
A sample point extraction unit (323) extracts natural defect candidate portions by using sample points comprising height data for one line obtained by scanning once around the measurement surface of a tire surface. Natural defect candidate portions include natural defect portions and intentional irregularity portions, such as characters and patterns. A differentiation unit (325) stores, in advance, conditions characteristic of the shape of intentional irregularity portions formed on the measurement surface, and from among the natural defect candidate portions, excludes natural defect candidate portions that satisfy those conditions from the natural defect candidate portions. Due to this configuration, intentional irregularity portions are differentiated from natural defect portions.
