PROBLEM TO BE SOLVED: To provide an apparatus, method and program for generating body rebuilding model shape data, which are capable of easily generating a rebuilding model to rebuild a defective body part inexpensively.SOLUTION: Three-dimensional shape measurement data of a body part are adjusted (S1, S2), a mesh is generated based on the data, and a peak of the mesh is laid out on a surface of the body part of a subject to be rebuilt (S3). Peak data located on a periphery of the body part of the subject to be rebuilt are extracted and a reference bottom surface is projected based on the peak data (S4). Vector data, which start from the peak of on the reference bottom surface and ends at the peak of the mesh laid out on the surface of a normal healthy body part (S5). Three-dimensional shape data of the surface shape of the rebuilding model are generated based on inversion vector data and the peak data on the reference bottom surface of the defective body part (S6), and three-dimensional shape data of a whole shape of the rebuilding model are generated based on the three-dimensional shape data of the surface shape the whole shape thereof and the three-dimensional shape data of the surface shape of the defective body part (S7).COPYRIGHT: (C)2013,JPO&INPIT【課題】欠損身体部分を再建するための再建モデルを簡便且つ安価に作製することができる身体再建モデル形状データ作成装置及び方法並びにプログラムを提供する。【解決手段】身体部分の三次元形状の計測データを調整して(S1,S2)、データに基づきメッシュを生成し、このメッシュの頂点を再建対象の身体部分の表面に割り付ける(S3)。再建対象部分の周縁に位置する頂点データを抽出し、これら頂点データから基準底面を推定する(S4)。基準底面上の頂点を始点とし健常側身体部分の表面に割り付けたメッシュの頂点を終点とするベクトルデータを生成(S5)。反転ベクトルデータと欠損側基準底面の頂点データから再建モデルの表面形状の三次元形状データを生成し(S6)、この表面形状の三次元形状データと、欠損身体部分の表面形状の三次元形状データから、再建モデルの全体形状の三次元形状データを生成する(S7)。【選択図】図2
