Summary:The 3-D reconstruction of visible polyhedral faces from a pair of
general perspective views with the aid of a calibration plate is
addressed. A polyhedron is placed on a planar calibration plate and two
side views of both the polyhedron and the calibration plate are taken.
Through proper arrangements we may assume that in the two views a number
of polyhedral edges lying on the calibration plate and the whole
calibration plate boundary are visible. We present an online camera
calibration technique with the aid of the calibration plate and a
two-stage process to find the vertex/edge correspondences without
encountering the ambiguity problem of the conventional epipolar line
technique. We then give a closed form solution to the 3-D polyhedral
vertices visible in both images. We also describe other advantages of
using our method for the 3-D polyhedron reconstruction. Experimental
results show that the obtained 3-D polyhedral vertex coordinates are
rather accurate
