Abstract

La présente invention concerne un procédé de remplissage d’une base de données d’entraînement destinée à permettre l’entraînement d’un algorithme de localisation d’un élément de réseau, comprenant les étapes suivantes :génération d’un noyau de convolution, le noyau de convolution étant formé d’une matrice ayant un nombre de lignes et un nombre de colonnes choisis aléatoirement, et enregistrement en mémoire du noyau de convolution,application, à une pluralité de pixels d’au moins une image de zone géographique, d’un filtre de floutage correspondant au noyau de convolution, résultant en une image floutée,ajout de l’image floutée à la base de données d’entraînement, pour obtenir une base de données d’entraînement complétée.La présente invention concerne également un procédé de localisation d’un élément de réseau au sein d’une zone géographique d’intérêt, à l’aide d’un algorithme de localisation préalablement entraîné selon un procédé d’apprentissage comprenant un procédé de remplissage de base de données d’entraînement tel que défini ci-avant. Figure pour l’abrégé : Fig. 2 FIGURESThe present invention relates to a method for filling a training database intended to allow training of an algorithm for locating a network element, comprising the following steps: generation of a convolution kernel, the convolution kernel being formed of a matrix having a number of rows and a number of columns chosen randomly, and recording in memory of the convolution kernel, application, to a plurality of pixels of at least one image of geographical area, of a blurring filter corresponding to the convolution kernel, resulting in a blurred image, adding the blurred image to the training database, to obtain a completed training database. The present invention also relates to a method of location of a network element within a geographical area of interest, using a location algorithm previously trained according to a learning method comprising a method of filling training database as defined above.
