Texture Reconstruction and Surface Registration in Multi-view
Creating high resolution, temporally coherent 3D model sequence in
real-time performance capture systems based on multi-view photometric
stereo gains increasing interest recently. Accurate correspondences
across the captured sequence provide an important basis to improve
temporal coherence with useful information from neighboring frames.
However correspondence problem is difficult due to the aperture
problem, visibility change (occlusion/disocclusion), topology change
and inherent ambiguity. In this work, following a previously developed
deformation-graph-based coarse matching pass, we use a variant of
local ICP algorithm to register adjacent frames in fine scale. To
prevent tangential drifting in long sequence, we regularize the
correspondences with local isometric constraint. Our result proves
effective and robust to local visibility changes. To obtain high
resolution and fully texturized models, we resynthesize high
resolution detail from normal maps and reconstruct texture by solving
Poisson equation on surface. This approach guarantees smooth texture
transition between views and optimized coloring in occluded region.
