How does Correlator3D handle meridian convergence?
The Omega/Phi/Kappa (OPK) orientation system is defined in a projected system while the Roll/Pitch/Yaw (RPY) system is defined in a geographical system. In Correlator3D, processing occurs in a projected system. This means that if RPY is provided as input data, a conversion to OPK is first perfomed. This conversion does take into account the meridian convergence through a minimization based on geographical coordinates. Consequently, the conversion results may slightly differ from one project to another.
