Title:
SYSTEM FOR EVALUATING DETERIORATION OF STEEL SURFACE USING SELF STRUCTURIZING CHARACTER MAP
Document Type and Number:
Japanese Patent JP3648728
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a deterioration evaluation system using a method for evaluating deterioration of a steel surface by processing a photographed image of the steel surface, that corresponds to a different light amount or light source at the time of photographing, thereby improving accuracy of the deterioration evaluation.
SOLUTION: The deterioration of the steel surface is evaluated through a pre-processing process of converting image data so as to correspond to a UCS color indication system, an image classification process of classifying a subject image based on an environment and a condition at the time of photographing the image by using a self structurizing character map and a corrected opposed propagation network, a color region classification process of classifying the image into a group of regions of similar colors using a clustering method, and a deterioration determination process of determining a level of deterioration by fuzzy-matching the clustering result and a deterioration reference value.
