Abstract (en)

[origin: WO2014171867A1] The invention relates to a method for analysing images generated from at least one imaging system on at least one satellite. The method comprises providing at least three images of an area of interest from the at least one imaging system, where the at least three provided images are provided from at least three different angles,establishing point correspondence between the at least three provided images,generating at least two sets of three-dimensional information based on the at least three provided images, wherein the at least two sets of three-dimensional information are generated based on at least two different combinations of at least two of the at least three provided images of the area of interest,and comparing the at least two sets of three-dimensional information so as to determine discrepancies and providing information related to the imaging system and/or errors in the images based on the determined discrepancies. The invention also relates to a method for image correction, a system, a computer program and a computer program product.
