Abstract
(EN)
A plurality of representative points are selected from a point group obtained as a result of shape measurement of an object. According to the positional relationship between the representative points and points existing around the representative points, a main curvature at each representative point is calculated. According to the main curvature at the representative point, a curvature line generated. By using the curvature line, a curved surface is generated.
(FR)
L’invention concerne une pluralité de points représentatifs qui sont sélectionnés parmi un groupe de points obtenu par la mesure de la forme d'un objet. En fonction de la relation de position entre les points représentatifs et les points autour de ceux-ci, on calcule une courbure principale au niveau de chaque point représentatif. En fonction de la courbure principale au niveau du point représentatif, on génère une ligne de courbure. On génère une surface courbe à l’aide de la ligne de courbure.
(JA)
 対象物の形状測定結果として得られた点群の中から複数の代表点を選定し、代表点と代表点の周りに存在する複数の点との位置関係に基づいて、代表点における主曲率をそれぞれ算出し、代表点における主曲率に基づいて曲率線を作成し、この曲率線を用いて曲面を生成する。
