  • Patent number: 12332344
    Abstract: A method (100) for referencing a digital elevation model (10), involving a step of obtaining (110) two SAR images (12, 14) having a common area (15) that their area of overlap (16, 17) shares with the digital model (10); the method (100) involving, for the SAR images (12, 14), steps of: selecting (120) an AOI (18) in the common area (15); calculating (130) a simulated image (22) in the AOI (18); estimating (140) an offset (di,dj) between the simulated image (22) and the SAR image (12); the method (100) involving steps of selecting a reference point (26) in the AOI (18); projecting (160) the reference point (26) into the SAR images (12, 14) to obtain one connection point per SAR image (12, 14); correcting (170) the connection points by the offsets (di,dj); calculating (180) the readjusted reference point (26); referencing (190) the digital model (10).

  • Patent number: 11416968
    Abstract: A method for increasing spatial resolution of a MS image using a PAN image. For a portion of the scene, values of parameters of a scene model are obtained according to a resemblance between a simulated MS reflectance and the MS reflectance. A relative variation in the simulated MS reflectance is determined with respect to a simulated PAN reflectance near the values of parameters obtained. A difference between the PAN reflectance and a reflectance of a PAN image with reduced spatial resolution is estimated. An MS image with increased spatial resolution is determined, by adding to the MS reflectance a correction corresponding to a product of this difference and this relative variation. A corresponding image-processing system is also provided.

  • Patent number: 10810704
    Abstract: A method for processing an optical image acquired by a space vehicle or an aerial vehicle having a ground reflectance model and an atmospheric model, the atmospheric model having an aerosol model and a cloud model; determining optimal values of atmospheric model parameters to optimise the atmospheric model with respect to the image; determining correction parameter values for each layer of the atmospheric model, converting the image into a ground image with environmental effects according to the correction parameter values, converting the ground image with environmental effects into a ground image with no environmental effects according to the correction parameter values.
