Patent number: 11747141Abstract: Described are a system (200) and method arranged to provide improved geocoded reference data to a 3D map representation. The system comprises a storage (201) having stored thereupon a 3D map representation comprising a textured 3D representation provided with geocoded reference data and formed based on imagery, the imagery being associated to information relating to at least one imaging device which has captured the imaging. The system comprises further a processor (208) arranged to receive at least one new image associated to information related to an imaging device which has captured the new image, perform registration of the new image to the 3D map representation, determine corresponding points in the new image and the 3D map representation, and determine displacement data for a plurality of 3D positions in the 3D map representation based on the determined corresponding points in the new image and the 3D map representation.Type: GrantFiled: February 1, 2021Date of Patent: September 5, 2023Assignee: MAXAR INTERNATIONAL SWEDEN ABInventors: Folke Isaksson, Ola Nygren

Patent number: 9709395Abstract: A method is provided, which comprises generating at least three images of an area of interest from at least one imaging system, the generated images being provided from at least three different angles, establishing point correspondence between the provided images. The method further involves generating at least two sets of three-dimensional information based on the 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. The method further includes comparing the at least two sets of three-dimensional information so as to determine discrepancies, and providing information related to the imaging system or errors in the images based on the determined discrepancies.Type: GrantFiled: April 19, 2013Date of Patent: July 18, 2017Assignee: VRICON SYSTEMS AKTIEBOLAGInventors: Johan Bejeryd, Johan Borg, Folke Isaksson, Leif Haglund, Per Carlbom, Ola Nygren, Ingmar Andersson

Patent number: 9704041Abstract: A method for classifying a terrain type in an area is provided, which comprises the steps of obtaining a plurality of overlapping aerial images of the area, calculating at least one terrain type index for each part of each of the aerial images which lies in the area, where the at least one terrain type index represents the terrain type, determining at least one terrain type index for each part of the area based on the calculated at least one terrain type index for each part of each of the aerial images, and classifying the parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined condition relates to a value of the determined at least one terrain type index. Also provided is a system and a computer program product.Type: GrantFiled: May 10, 2016Date of Patent: July 11, 2017Assignee: Vricon Systems AktiebolagInventors: Leif Haglund, Folke Isaksson, Per Carlbom, Ola Nygren, Johan Borg, Sanna Ringqvist, Anton Nordmark

Patent number: 9547935Abstract: The invention relates to a method for building a 3D model of an area of interest on the surface of a planet. The method comprises providing a plurality of 2D images from satellites, where each 2D image out of the plurality of 2D images at least partly covers the area of interest. Also, each subarea of the area of interest is covered by at least two images, taken from different angles, out of the plurality of 2D images. Bundle adjustments are performed for the plurality of 2D images and the area of interest is divided into parts. For each part of the area of interest at least one combination and preferably all possible combinations out of two images covering that part of the area of interest are taken. Said two images are taken from the at least two images, taken from at least two different angles, out of the plurality of 2D images. Further, for each part of the area, point matching correspondence is established for a set of points for each such combination of two images.Type: GrantFiled: February 24, 2014Date of Patent: January 17, 2017Assignee: Vricon Systems ABInventors: Leif Haglund, Ola Nygren, Folke Isaksson, Johan Borg
