i.ortho.init: roll,pitch and yaw should not be presented as equivalent to omega, phi, kappa
|Reported by:||mlennert||Owned by:|
The man page of i.ortho.init says
The INITIAL values for (omega,phi,kappa) are expressed in degrees, and represent an approximation for the cameras attitude at the time of exposure. Omega (roll): Raising or lowering of the wings (turning around the aircraft's axis); Phi (pitch): Raising or lowering of the aircraft's front (turning around the wings' axis); Kappa (yaw): Rotation needed to align the aerial photo to true north: needs to be denoted as +90 degree for clockwise turn and -90 degree for a counterclockwise turn.
However, according to PCI Geomatics and other software manuals, roll, pitch and yaw are not equivalent to omega, phi, kappa, as the former are expressed relative to a local plane, while the latter are expressed relative to a projection system plane.
Someone more knowledgeable than me should verify this, but probably the man page needs precision concerning what exactly is expected in the module.
