Abstract

Procédé (100) d’amélioration de la géolocalisation d’images acquises par défilement d’un capteur (1) d’images le long d’une trajectoire de défilement du capteur (1), ledit capteur étant configuré pour acquérir au moins un segment d’images (2, 3) au cours d’une période de temps, l’au moins un segment d’images (2, 3) comprenant une suite d’images de la surface de la terre acquises, à partir de positions successives du capteur le long de la trajectoire de défilement, à des instants successifs de la période de temps, le procédé comprenant l’étape suivante : - détermination (102) d’au moins un nouveau segment (5) d’images acquises au cours d’une nouvelle période de temps qui respectivement commence et se termine à l’intérieur de la période de temps de l’au moins un segment d’images (2, 3), l’au moins un nouveau segment (5) d’images comprenant une nouvelle suite d’images acquises à des instants successifs de la nouvelle période de temps, la nouvelle suite d’images couvrant une zone géographique observée par le capteur sur la surface de la terre pendant la nouvelle période de temps, ladite zone géographique observée étant définie par au moins un paramètre de découpage. Figure 1Method (100) for improving the geolocation of images acquired by scrolling an image sensor (1) along a scrolling trajectory of the sensor (1), said sensor being configured to acquire at least one image segment (2, 3) over a period of time, the at least one image segment (2, 3) comprising a series of images of the surface of the earth acquired, from successive positions of the sensor along the scrolling trajectory, at successive times of the period of time, the method comprising the following step: - determining (102) at least one new segment (5) of images acquired over a new period of time which respectively begins and ends within the time period of the at least one image segment (2, 3), the at least one new segment (5) of images comprising a new series of images acquired at successive times of the new period of time, the new series of images covering a geographic area observed by the sensor on the surface of the earth during the new time period, said observed geographic area being defined by at least one clipping parameter.
