Title:
ANALYSIS METHOD FOR IMAGES OF FIBER-CONTAINING PRODUCTS AND PROGRAM AND ANALYSIS DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/149425
Kind Code:
A1
Abstract:
The present invention estimates a fiber structure from an image of a product that includes fibers. This method for analyzing images of products that include fibers includes: a step (STEP 1) in which a three-dimensional image (310) of a product including fibers is obtained; a step (STEP 2) in which the fibers in the three-dimensional image (310) are converted into a particle aggregate; and steps (STEPS 3, 4) in which the fiber structure is estimated on the basis of the positional relationship of each particle included in the particle aggregate (320).
