1. An apparatus for capturing panoramic or semi-panoramic 3D scenes, the apparatus comprising:

  • a mirror comprising a mirror surface composed of mirror plane surfaces, arranged like sides of a pyramid or clipped-pyramid with a polygonal base and an axis;

    a plurality of camera pairs each of which is associated with a respective one of the mirror plane surfaces and directed towards the respective associated mirror plane surface, so that the plurality of camera pairs look into substantially radial directions via the respective associated mirror plane surface,wherein, for each camera pair, virtual positions of pivot points of the cameras of the respective camera pair are offset from each other along a straight baseline which is offset from the axis, anda 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,wherein center points of the baselines of all stereo camera pairs lie on a circle with radius d around axis within a deviation of 10% of d, and the length of the baselines varies within 10% of a mean baseline length B with
