Abstract
(EN)
A method for determining an exact location of an imaging device can include detecting a first object and determining its approximate location based on an approximate location of the imaging device, and determining a reliability value of the approximate location; receiving a predefined location of a second object from a memory, and determining whether the predetermined location of the second object matches, within a pre-specified margin of error, the approximate location of the first object, and when there is a mismatch greater than the pre-specified margin of error, storing the first object and its approximate location on a distributed ledger, and when there is a match within the pre-specified margin of error, determining the exact location of the imaging device based on the predefined location stored in the memory.

L'invention concerne un procédé permettant de déterminer un emplacement exact d'un dispositif d'imagerie, qui peut consister : à détecter un premier objet et déterminer son emplacement approximatif en fonction d'un emplacement approximatif du dispositif d'imagerie, et à déterminer une valeur de fiabilité de l'emplacement approximatif ; à recevoir un emplacement prédéfini d'un second objet à partir d'une mémoire, et à déterminer si l'emplacement prédéterminé du second objet correspond, à l'intérieur d'une marge d'erreur prédéfinie, à l'emplacement approximatif du premier objet, et lorsqu'il y a un décalage supérieur à la marge d'erreur prédéfinie, à mémoriser le premier objet et son emplacement approximatif dans un registre distribué, et lorsqu'il y a une correspondance à l'intérieur de la marge d'erreur prédéfinie, à déterminer l'emplacement exact du dispositif d'imagerie en fonction de l'emplacement prédéfini enregistré dans la mémoire.
