摘要： A method for generating 3D-information from multiple images showing a 3D scene from multiple perspectives has: providing at least two hypotheses for the 3D-information; performing a multi-hypotheses test by matching the at least two hypotheses to the multiple images and determining a test-result hypothesis that fulfills a particular matching criterion; updating the test-result hypothesis by varying a parameter set of the test-result hypothesis to further improve the matching criterion or another criterion; and determining the 3D-information on the basis of the parameter set of a resulting hypothesis provided by the action of updating the test-result hypothesis. A corresponding computer readable digital storage medium and a 3D-information generator are also described. Further embodiments perform a correspondence analysis between projections of spatio-temporal objects (STO) in multiple images to select a particular spatio-temporal object on the basis of said correspondence analysis.

摘要： A provision of high quality panoramic or semi-panoramic 3D scenes is achieved at reasonable efforts by arranging the plurality of camera pairs, each of which is associated with a respective one of mirror plane surfaces of a pyramid or clipped-pyramid shaped mirror in that same is directed towards the respective associated mirror plane surface, such that for each camera pair the virtual positions of pivot points of the cameras of the respective camera pair are offset from each other along a straight baseline which, in turn, is offset from the axis of the mirror, and a distance between virtual points of a left-hand channel camera of a first camera pair associated with a first mirror plane surface and a right-hand channel camera of a second camera pair associated with a second mirror plane surface positioned neighboring the first mirror plane surface, deviates from a length of the baselines of the camera pairs by less than 10% of the length of the baselines.
