Reconstruction of~3-D Rigid Smooth Curves Moving Free when Two Traceable Points Only are Available
This work addresses a specific challenge in computer vision or motion analysis for applications like tracking or modeling, but it appears incremental as it builds on previous research by reducing point requirements.
The paper tackles the problem of reconstructing 3D rigid smooth curves from orthogonal projections with minimal traceable points, reducing the requirement from three to two points for free motion, which improves upon prior best results.
This paper extends previous research in that sense that for orthogonal projections of rigid smooth (true-3D) curves moving totally free it reduces the number of required traceable points to two only (the best results known so far to the author are 3 points from free motion and 2 for motion restricted to rotation around a fixed direction and and 2 for motion restricted to influence of a homogeneous force field). The method used is exploitation of information on tangential projections. It discusses also possibility of simplification of reconstruction of flat curves moving free for prospective projections.
