  • Patent number: 10043417
    Abstract: The method according to the invention is a method for showing the localization error of a plurality of points of a georeferenced image, comprising the following steps: providing a georeferenced image, in which each image coordinate point is associated with announced values of the geographical coordinates defining the geographical localization of the object corresponding to that point of the georeferenced image; showing the georeferenced image. The method also comprises the following steps: providing, for each point of the plurality of points of the georeferenced image, an estimated value of the localization error specific to that point, said error not being uniform over the image; and showing the localization error for at least one point among the plurality of points of the georeferenced image so as to make it possible for a user to view the localization error.

  • Patent number: 8855439
    Abstract: The invention relates to a method for determining a localization error (?) of a point (P0) of a raw image, comprising the following steps: estimating the value of a statistical magnitude (G) characteristic of a probability law (D(X, Y, Z)) of at least one terrain coordinate (X, Y, Z) associated with the point (P0) of the raw image, using a probability law (D(?1, . . . , ?n)) with magnitudes (?1, . . . , ?n) depending on the exposure conditions of the raw image and a localization function, deduced from an exposure function and a terrain model and applied for the image coordinate point (P0) of the raw image; and deducing the localization error (?) of the point (P0) of the raw image from the statistical magnitude (G).
