Abstract

Méthode de traitement de blocs de données séquentiels comprenant la répétition des étapes suivantes pour des blocs de données successifs : lacquisition dau moins un bloc de référence comprenant des points de données et un bloc courant de points de données; lidentification dun ensemble de points dancrage dans le bloc de référence; lattribution dun vecteur de mouvement à chaque point dancrage du bloc de référence pour évaluer lemplacement du point dancrage dans le bloc courant; la définition de polygones formés de points dancrage dans le bloc de référence, chaque polygone contenant des points de données dans le bloc de référence, et chaque polygone et point de données contenus dans le polygone ayant un emplacement prédit dans le bloc courant selon les vecteurs de mouvement attribués aux points dancrage dans le polygone; pour au moins un des polygones du bloc de référence, lajustement du nombre de points dancrage dans le bloc de référence selon la précision des emplacements prédits des points de données dans le bloc courant; et si le nombre de points dancrage augmente par lajout de nouveaux points dancrage, lattribution de vecteurs de mouvements aux nouveaux points dancrage pour évaluer lemplacement des points dancrage dans le bloc courant.
