 note = {港湾施設で使用される鋼矢板の厚さ測定は，損傷や劣化などの形状変化による性能低下を検査するために必要である．水中港湾鋼構造物の維持管理のために，効率的かつ高精度な板厚測定手法が望まれている．われわれはこれまでに，鋼板の厚さが一定の条件下での空間周波数フィルタを用いた非接触式超音波板厚測定法を提案し，模擬実験により性能を評価した．しかし鋼板の厚さが異なる場合においては，精度が低下する可能性がある．そこで本稿では傾斜を持つ鋼板に提案手法を適用し，精度の評価を行った．, Thickness gauging of steel sheet piles used in port facilities is necessary to inspect performance deterioration due to shape changes such as damage and deterioration. For the maintenance of underwater harbor steel structures, an efficient and highly accurate thickness gauging method is needed. We have proposed a non-contact ultrasonic thickness gauging method using a spatial frequency filter and evaluated its performance by simulated experiments. However, in case the thickness of the steel plate is not constant, the accuracy may decrease. In this paper, we evaluated the accuracy using proposed method for inclined steel plate.},
