Description
本願は、2000年4月28日に出願された米国特許出願第09/560,131号、2000年4月28日に出願された米国特許出願第09/560,132号、2000年4月28日に出願された米国特許出願第09/560,583号、2000年7月13日に出願された米国特許出願第09/616,093号、2000年4月28日に出願された米国特許出願第09/560,645号、2000年4月28日に出願された米国特許出願第09/560,644号、2000年4月28日に出願された米国特許出願第09/560,584号及び2000年4月28日に出願された米国特許出願第09/560,133号の優先権を主張し、それらの教示全体を参照によって本願に組み入れたものとする。
本発明は、主に物体のマッピングに関し、より具体的には、物体の三次元モデルを作ることと、物体の部分を位置合わせして物体のモデルを作製することと、物体の走査された部分を位置合わせして三次元物体を提供することと、解剖学的構造物を走査して治療且つ診断し、さらに、医療及び歯科装置及び器具を開発し製造することと、特定の画像を提供して物体のマッピングを補助することと、に関する。
補綴、矯正等の解剖学的装置及び歯列矯正等の器具を作製することができることは、よく知られている。解剖学的装置を作製する現在の方法は、主観的であり、それによって、医者は、自分の解剖学的構造物に対する見解、装置が使用される場所、及び、医者の経験及び類似状況の記憶等の主観的な基準に基づいて、解剖学的装置の仕様を定めるかまたは設計する。そのような主観的な基準は、結果として、医者によって変動が大きくなりうる解剖学的装置が開発されることになり、他者が使用することができる知識のデータベースを獲得することを妨げる。
本発明の特定の実施形態にしたがって、表面に画像が投影される。画像は、表面を測定しマッピングするのに使用される複数の個別形状を有するパターンを含むことができる。複数の個別形状は、投影された形状の投影軸及び視軸に関連した点によって形成された平面に平行な方向に検出可能である特徴部を含む。画像は、複数の形状を個別に識別するためのコード化された情報を含む特徴部をさらに備える。コード化された特徴部は、投影軸及び視軸の点によって形成された平面に実質的に直交する方向に変動し、複数の個別形状の各々からの別個の特徴部であり得、複数の個別形状に一体的な特徴部であり得、且つ/または、複数の個別形状から異なる時間間隔で表示されることができる。投影軸及び視軸に沿った点によって形成された平面に実質的に垂直な線に沿ってコード化された情報が検索されるように、コード化された情報を含む特徴部は配向される。特徴部の使用は、マルチフレーム参照独立走査を実施するために使用される。特定の実施形態において、走査されたフレームは互いに対して位置合わせされる。
