Abstract
(EN)
Disclosed are a method and a device for correcting image sensor misalignment. A method for correcting image sensor misalignment according to an embodiment of the present invention may comprise the steps of: acquiring a ship image from an image sensor; acquiring ship identification information from an automatic ship identification device (AIS); and correcting a misalignment value of the image sensor by using first coordinates of a ship, which is calculated from the ship image, and second coordinates of the ship, which is calculated from the ship identification information.

L'invention concerne un procédé et un dispositif permettant de corriger un désalignement de capteur d'image. Selon un mode de réalisation de l’invention, un procédé permettant de corriger un désalignement de capteur d'image peut comprendre les étapes consistant à : acquérir une image de navire à partir d'un capteur d'image ; acquérir des informations d'identification de navire à partir d'un dispositif d'identification de navire automatique (AIS) ; et corriger une valeur de désalignement du capteur d'image en utilisant les premières coordonnées d'un navire, qui sont calculées à partir de l'image du navire, ainsi que les secondes coordonnées du navire, qui sont calculées à partir des informations d'identification du navire.
