| Research Abstract |
In order to manufacture a pair of shoes fitted to individuals, it is necessary to prepare shoe lasts for them. If the manufacturer could find a suitable last among the last stock instead of making one and reuse it, the manufacturing cost and time will reduce remarkably. Therefore I proposed similarity measures of curved surfaces of shoe lasts. The surfaces of shoe lasts are, unlike those of general objects, have some important cross-sectional shapes which are determined by the design process of it from human foot. I utilized these cross-sectional shapes to develop the similarity measures by comparing the corresponding shapes between the two last shapes of point cloud obtained by a 3D scanner.
