Metric reconstruction of straight homogeneous generalized cylinders with elliptical cross-section from a single image
Richen Liu, Zhihong Wu, Dequan Guo · Journal of Electronic Imaging · 2015
A new three-dimensional metric reconstruction method for straight homogeneous generalized cylinders with elliptical cross-section (SHGC-E) from a single image is addressed. By using an elliptical truncated cone shape, the elliptical cross-section is computed by back-projection. The conditions under which the imaged limb can be considered an imaged meridian under perspective projection are discussed and proved. Furthermore, the imaged meridian of SHGC-E is identified and recovered by some of the proposed special properties of SHGC-E.
