The present invention relates to a method and apparatus for unambiguously determining the 3D orientation of a human head in 3D shape modeling. The apparatus of the present invention includes a headband located on the patient's head, a pair of temples secured to the headband, and a front housing rotatably coupled to the temple and having at least two cameras, The cameras are positioned inside the front housing so that each of the two anthropological reference lines placed on the face and connecting the orbital and earpoints on both sides of the patient's head is picked up within the field of view of each camera. The front housing further includes a 3D compass that is placed on a measurement surface that coincides with a plane composed of these two reference lines when the two reference lines are aligned side by side, such a 3D compass being a compass itself Quantitatively measures the 3D direction of the patient's head when is positioned on the measurement surface. [Selection] Figure 6本発明は、３Ｄ形状モデリングにおける人間の頭の３Ｄ方向を明確に決定する方法と装置に関する。本発明の装置は、患者の頭に位置するヘッドバンド、ヘッドバンドに固定される１対のテンプル、及びテンプルに回転可能に連結され、少なくとも２台のカメラを備えた前方ハウジングを含み、患者の顔面に置かれて患者の頭の両側の眼窩点と耳点を連結する２個の人類学的基準線の各々を各々のカメラの視野内でピックアップするようにカメラが前方ハウジングの内部に位置し、２個の基準線が並んで整列された時、これらの２個の基準線からなる平面に一致する測定面に置かれる３Ｄコンパスを前記前方ハウジングがさらに含み、このような３Ｄコンパスはコンパスそのものが前記測定面に位置した時の患者の頭の３Ｄ方向を定量的に測定する。【選択図】図６
