Abstract:
1. A method for capturing three-dimensional images of objects using two cameras having overlapping image areas, wherein a configuration of the two cameras being pre-calibrated, which comprises the steps of: determining positions and orientations of the two cameras relative to one another; establishing a transformation, the transformation assigning exactly one position in space, namely one voxel, in a three-dimensional image space to a first image position, namely a position of a pixel, of an image captured using a first of the cameras and a second image position, being a position of a pixel, of an image captured using a second of the cameras; determining, during a course of a calibrating procedure, a family of epipolar lines for each of the cameras, exactly one epipolar line of the second camera being assigned to each of the epipolar lines of the first camera; projecting a predetermined random image onto an object to be imaged, individual pixels of the predetermined random image having one of at least two different color values and/or intensity values and in that then, for each pixel of the first camera: performing the following steps for each pixel of the image captured by the second camera which are situated on the second epipolar line:
