Abstract

Pour identifier ou détecter par exemple un oléoduc sous-marin, on utilise dans l'état actuel de la technique des procédés à base de modèles dans lesquels on calcule d'abord l'espace de solution global au moyen des images individuelles obtenues par synthèse puis on compare une image fournie par un sonar à chaque image de synthèse individuelle de l'espace de solution global. Ceci exige des capacités de calcul et/ou de mémoire de travail énormes, de sorte que ces solutions sont inapplicables dans les engins sous-marins autonomes (AUV, autonomous underwater vehicle). L'invention concerne donc un procédé d'identification ou de détection d'une structure immergée qui comprend les étapes suivantes : détermination d'une image d'origine au moyen d'un sonar à balayage latérale (à ouverture synthétique) monté sur un engin nautique, en particulier sur un engin submersible ; détermination d'une position de l'engin nautique et/ou de la structure immergée afin d'obtenir une information supplémentaire ; détermination d'un espace d'images de référence contenant des images de référence associées à partir de l'information supplémentaire et de la géométrie connue de la structure immergée de façon à obtenir un espace d'images de référence réduit ; et comparaison de l'image d'origine avec les images de référence déterminées pour l'espace d'images de référence réduit afin de détecter et/ou identifier la structure immergée.
