项目摘要

4枚の帯金具の形状に対して、2枚ずつ6通りの組み合わせの形状比較を行うことにより、それぞれに類似性を数量化した。その全組み合わせの評価した結果、4枚の帯金具のうち二つの組み合わせがよく一致していることが判明した。前年度までの研究成果を基に、2枚ずつ帯金具をBMPデータで重ね合わせてみたところ、帯金具を構成する部分形状の位置関係の一致度を考慮する必要性が認められた。すなわち、部分形状同志は一致しているもののその位置関係に違いがみられた。そこで、当該年度は部分形状を考慮した帯金具の一致度について研究を進めた。その手法・手順について以下に述べる。①前年度に開発した手法により二つの帯金具形状の測定データ間の座標系を一致させる。②二つの帯金具形状に対して部分形状領域を指定し、文様の特徴部分である凹極小値を前後10点から抽出する。③それぞれの部分形状の凹部分を用いて照合処理を行う。④他方の帯金具形状に対する部分形状の位置と照合度合い(照合値)を求める。⑤照合位置の近さと照合度合いのあたいから二つの形状の一致具合を定量化する。今回照合方法について、測定誤差，画像データへ変換する際の量子化誤差，座標系一致誤差，および形状の違いなどから、極値間の距離に許容範囲を設け照合結果を算出した。すなわち、一方の帯金具の部分形状の極小値近傍に他方の部分形状の極小値が存在する場合に模様は一致しているとみなし，極小値の全体個数に対する一致する個数の割合で照合値をもとめる．今回の実験では許容範囲が１の場合の照合結果で、帯金具2種類の対の照合結果が0.5を超え、高い一致度を示した。

4 pieces of metal fitting shape matching, 2 pieces of metal fitting shape matching, 6 pieces The results of the evaluation of the whole set of accessories, the results of the evaluation of the combination of the two sets of accessories, the results of the evaluation of the two sets of accessories, the results of the evaluation of the two sets of accessories, the results of the evaluation of the two sets of accessories, the results of the evaluation of the evaluation of the three sets of accessories, the results of the evaluation of the evaluation of the three sets of accessories, the results of the evaluation of the evaluation of the three sets of accessories, the results of the evaluation of the evaluation of the three sets of accessories, the results of the evaluation of the four sets of accessories, the results of the evaluation of the three sets of accessories, the results of the evaluation of the three sets of accessories, the evaluation of the four sets of accessories, the results of the evaluation of the three sets of the evaluation of the four sets of accessories, the evaluation of Based on the research results of the previous year, it is necessary to consider the consistency of the position relationship of the two kinds of BMP fittings. In addition, some of the shapes of homosexuality are consistent with the position of the body. When the shape of the part of the year is considered, the consistency of the fittings is considered. The following is a description of the method and the procedure.① The coordinate system between the two fitting shapes is consistent with each other in the previous year's development method. 2. Specify the shape of the fitting part, and the concave minimum value of the characteristic part of the text before and after 10 points. 3. The shape of the concave part of the shape is used to match the shape of the line. 4. Find the position of the shape of the fitting in the other side and the matching value (matching value) (5) Quantify the coincidence of the shape and position of the photograph. This paper describes the calculation of the error of measurement, quantization error during image transformation, coordinate system consistency error, shape deviation, distance between poles, and allowable tolerance range. The minimum value of part of the shape of the fitting on one side is close to the minimum value of part of the shape of the fitting on the other side. The results of this experiment show that the allowable tolerance range is 1, and the results of this experiment show that the allowable tolerance range is 1, and the results of this experiment show that the allowable tolerance range is 1, and the results of this experiment show that the allowable tolerance range is 1.
