Claims (7)
- 眼底画像を作成するためのカメラおよび照明ユニットを備えた眼底検査装置の作動制御方法であって、
カメラ位置および/または照明ユニットの最適化が、画像評価手段による、事前設定可能のパターン認識アルゴリズムによる自動分類後に、検出確実性に従って制御手段により制御および/または調整され、
前記画像評価手段において、疾患に特徴的であるデータが提供され、評価された画像のデータが、提供されたデータと相関され、前記制御手段において、前記相関で検出された前記データの一致に応じてパラメータが生成され、前記パラメータが、検出された一致がより明瞭になるように、閉制御ループでカメラおよび/または照明ユニットの調整ユニットに与えられることを特徴とする、方法。 - 作成された画像に含まれるパターンが、少なくとも1つの疾患に対応する知られているパターンと比較され、決定されたデータに応じて、カメラおよび/または照明ユニットの新規調整のためのパラメータが決定され、それに続き前記パラメータを用いて、閉制御ループで調整ユニットを用いてカメラおよび/または照明ユニットの調整が変更されることを特徴とする、請求項1に記載の方法。
- パターン認識アルゴリズムを用いて、自動分類が実施されることを特徴とする、請求項1または2に記載の方法。
- 検出確実性に関する最適化が、好ましくは所定のパターン認識アルゴリズムによる自動分類の後で、カメラおよび/または照明ユニットの調整または位置により制御および/または調整されることを特徴とする、請求項1から3のいずれか一項に記載の方法。
- カメラおよび/または照明ユニットの調整が、分類アルゴリズムを介して制御および/または調整されることを特徴とする、請求項1から4のいずれか一項に記載の方法。
- カメラおよび照明ユニットとしてレーザーが使用され、調整ユニットを用いて、レーザーの位置、および/またはレーザービームの走査領域、および/またはレーザービームの強度、および/または特に光学系を用いて走査領域、および/またはレーザービームの焦点が、変更されることを特徴とする、請求項1から5のいずれか一項に記載の方法。
- コンピュータを用いてパターン認識のためにデータが提供され、および/または疾患に特徴的なパターンまたはデータが提供されることを特徴とする、請求項1から6のいずれか一項に記載の方法。
