Description
(i)歯牙を含む第1のビデオ画像フレームを取り込み、第1のビデオ画像フレームを処理して、第1のビデオ画像フレーム内で歯牙の1つ以上のエッジを検出すること、
(ii)歯牙を含む第2のビデオ画像フレームを取り込み、第2のビデオ画像フレームを処理して、第2のビデオ画像フレーム内で歯牙の1つ以上のエッジを検出すること、
(iii)処理された第1のビデオ画像フレームと処理された第2のビデオ画像フレームとの間で対応するエッジ位置を比較すること、によって検出し、検出されたカメラ移動に応じて、フリンジパターン照明を口腔内カメラから歯牙に投影し、フリンジパターンの1つ以上の静止画像を取得及び記憶すること、を含む。
Claims (3)
- 少なくとも部分的にはコンピュータによって実行される歯牙の輪郭画像の取得方法であって、
口腔内カメラ内のビデオ撮像システムからのビデオ画像を用いて、前記口腔内カメラの移動を、
(i)前記歯牙を含む第1のビデオ画像フレームを取り込み、前記第1のビデオ画像フレームを処理して、前記第1のビデオ画像フレーム内で前記歯牙の1つ以上のエッジを検出すること、
(ii)前記歯牙を含む第2のビデオ画像フレームを取り込み、前記第2のビデオ画像フレームを処理して、前記第2のビデオ画像フレーム内で前記歯牙の前記1つ以上のエッジを検出すること、
(iii)前記処理された第1のビデオ画像フレームと前記処理された第2のビデオ画像フレームとの間で対応するエッジ位置を比較すること、
によって検出し、
過度の前記口腔内カメラの移動が検出された場合、歯牙の輪郭画像を生成させることなく前記口腔内カメラの移動を検出する処理に戻り、
前記口腔内カメラの移動が検出されなかった場合、フリンジパターンの照明を前記口腔内カメラから前記歯牙に投影し、前記フリンジパターンの1つ以上の静止画像を取得及び記憶し、前記フリンジパターンの前記1つ以上の静止画像を用いて前記歯牙の表面の3次元画像を形成及び表示する、
ことを含む方法。 - 前記口腔内カメラの位置が変化すると、どのフリンジパターン画像が必要とされるかを計算し、口腔内カメラの位置を自動的に決定し、投影パターン画像を取得するステップをさらに含み、前記第1のビデオ画像フレームが前記第2のビデオ画像フレームに時間的に隣接している、請求項1に記載の方法。
- 歯牙の撮像装置であって、
(i)前記歯牙のビデオ画像またはフリンジパターン画像の画像データを取り込む検出器、
(ii)前記歯牙の輪郭撮像を可能にするために操作可能なスイッチ、
(iii)前記ビデオ画像用に前記歯牙に向けて光を投影する第1の照明源、及び
(iv)カメラ移動を示す移動信号に応じて、輪郭撮像用にレーザ光ビームを前記歯牙上に走査するように通電可能なフリンジパターン発生器、
を有する口腔内カメラと、
前記検出器によって取り込まれた前記画像データを受け取り、前記歯牙の輪郭画像を生成するために前記口腔内カメラと信号通信を行うコンピュータと、
前記口腔内カメラの内部にある、または前記コンピュータに搭載された制御ロジックプロセッサであって、前記ビデオ画像を解析して前記歯牙に対するカメラ移動を示す前記移動信号を提供する制御ロジックプロセッサと、
前記ビデオ画像及び前記輪郭画像を表示するために前記コンピュータと信号通信を行うディスプレイと、
を備え、
前記制御ロジックプロセッサは、
前記口腔内カメラが過度に移動していると判定した場合、前記フリンジパターン発生器にレーザ光ビームを走査させず、
前記口腔内カメラが静止していると判定した場合、前記フリンジパターン発生器にレーザ光ビームを走査させ、前記コンピュータに前記歯牙の輪郭画像を生成させる装置。
