ABSTRACT:
A computer receives a number of groups of projection images of a reference object already known to the computer. Each projection image was captured via a recording arrangement with corresponding positioning of the recording arrangement. The computer uses one projection image for the respective position of the recording arrangement to determine an interim projection matrix, which describes a mapping of the three-dimensional space to a projection image captured with the respective positioning of the recording arrangement. The interim projection matrices relate to coordinate systems that are specifically assigned to each group. The computer uses interim projection matrices of different groups determined for the same position of the recording arrangement to determine locations of the other coordinate systems related to one of the coordinate systems. The computer uses the interim projection matrices and locations of the other coordinate systems to define a final projection matrix, that relates to a uniform coordinate system, for every position of the recording arrangement.
