ABSTRACT
We present an iterative algorithm to reconstruct a 3D
object surface from a sparse set of matched feature points
on the input stereo images of the object. The initial matches
are sparse and do not have to be accurate. The reconstructed
3D surface is represented in terms of triangular polygons
whose vertices are initially the 3D points corresponding to
these matched feature points. In order to render photorealis­
tic images of the surface, these feature points are iteratively
updated. New feature points are added into the feature point
set as well as the depth estimates of the feature points are re­
fined. Experimental results showing the updated correspon­
dences, reconstructed surfaces and virtual views rendered
from new directions are presented.
