Overview | Angle conventions | Case study: beak gape angle in bellbirds | Step 1: define the directed vectors | Step 2: describe the observed 2D projections | Step 3: include measured view elevation | Step 4: include approximate yaw | Step 5: use physical length to constrain foreshortening | Biological application: estimating gape | What if I'm interested in yaw? | Choosing candidate values

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.
