Claim 7:
8. The three-dimensional geometry measurement apparatus according to claim 1, wherein
the calculation part further includes a storage part that stores a table in which (i) three-dimensional coordinates of individual grid points of a measurement space of the plurality of measurement systems, the measurement space being divided with cubic grids at equal intervals, (ii) a plurality of the correction values, and (iii) an index for identifying each of the measurement systems are associated with each other, wherein
the correction part reads, from the storage part, the correction value which is associated with the three-dimensional coordinates of the grid point closest to the three-dimensional coordinates indicated by the target measurement data and the index indicating the measurement system corresponding to this grid point, and corrects the preliminary measurement data on the basis of the read correction value.
