Trplp-trifocal relative pose from lines at points
We present a method for solving two minimal problems for relative camera pose estimation
from three views, which are based on three view correspondences of (i) three points and one …

From multiview image curves to 3D drawings
Reconstructing 3D scenes from multiple views has made impressive strides in recent years,
chiefly by correlating isolated feature points, intensity patterns, or curvilinear structures. In …
