Abstract

La présente invention concerne un procédé de détermination de l'épaisseur de brin d'au moins un brin d'un filet immergé, le procédé comprenant les étapes consistant à déplacer un ensemble sous-marin sur le filet submergé tandis que l'ensemble sous-marin adhère au filet, collecter des données d'image à partir d'une caméra barrette de l'ensemble sous-marin lorsque l'ensemble sous-marin adhère au filet immergé et se déplace sur celui-ci, générer, par un ordinateur embarqué de l'ensemble sous-marin, une image bidimensionnelle d'une partie du filet submergé sur la base des données d'image reçues, et déterminer, par l'ordinateur embarqué de l'ensemble sous-marin, l'épaisseur de brin dudit brin du filet submergé sur la base de l'image bidimensionnelle.
