A line-photogrammetric mathematical model for the reconstruction of polyhedral objects

Examples:

The three images and the image line measurements:








The three models below result from adjustment with an increasing amount of object information

Remarks:

  • Ellipsoids are enlarged by a factor of 10.
  • Very flat (small) ellipsoids do not display in some browsers.
  • The models have been tested with CosmoPlayer, GLView, VRWeb, Live3D, and WorldView.
  • Ellipsoids do not display correctly in WorldView(2.0).

Only coplanarity constraints within each face:
