araponga - Estimate 3D Orientations from 2D Landmarks
Estimates possible 3D orientations of directed objects
from the 2D image coordinates of two landmarks and any
additional information about the imaging geometry or object.
Because a 2D image generally does not uniquely determine a 3D
orientation, the package returns sets of compatible pitch, yaw,
and view-elevation angles rather than a single unconstrained
estimate.
