Title
(DE) VERFAHREN ZUM AUFFASSEN EINES ZIELS
(EN) METHOD FOR DETERMINING A TARGET
(FR) PROCÉDÉ DE DÉTECTION D'UNE CIBLE
Abstract
(DE)
Die Erfindung geht aus von einem Verfahren zum Auffassen eines Ziels (36), bei dem ein das Ziel (36) abbildendes Bild (28) vorgegeben wird und eine Zielerkennungseinheit (18) aus Bildmerkmalen des Bilds (28) und vorgegebenen Klassifikatoren (56) das abgebildete Ziel (36) als solches erkennt. Um eine zuverlässige Zielauffassung zu erreichen, wird vorgeschlagen, dass die Zielerkennungseinheit (18) anhand der Kenntnis des Ziels (36) neue Klassifikatoren (66) aus dem Bild (28) ermittelt, mit denen das Ziel (36) mit einer höheren Erkennungsgüte als mit den zur Erkennung verwendeten Klassifikatoren (56) als solches erkennbar ist.
(EN)
The invention relates to a method for determining a target (36), in which method an image (28) illustrating the target (36) is specified and a target identification unit (18) identifies the illustrated target (36) as such from image features of the image (28) and predefined classifiers (56). According to the invention, in order to determine targets reliably, the target identification unit (18) determines new classifiers (66) from the image (28) using knowledge of the target (36), by means of which classifiers the target (36) is identifiable as such with a greater identification accuracy than with the classifiers (56) used for identification.
(FR)
L'invention concerne un procédé de détection d'une cible (36), selon lequel une image (28) reproduisant la cible (36) est prédéfinie et une unité d'identification (18) de cible identifie la cible (36) reproduite en tant que telle à partir de caractéristiques de l'image (28) et de classifieurs (56) prédéfinis. L'objet de l'invention est d'obtenir une détection de cible fiable. À cet effet, l'unité d'identification (18) de cible détermine à partir de l'image (28) sur la base de la connaissance de la cible (36) de nouveaux classifieurs (66), au moyen desquels la cible (36) peut être identifiée en tant que telle avec une qualité d'identification plus élevée qu'avec les classifieurs (56) utilisés pour l'identification.
