Matching Geometric Models
via Alignment
via Alignment
Alignment
is the most common paradigm for matching
3D
models to either 2D or 3D data. The
steps are:
1. hypothesize a
correspondence between a set of model
points and a
set of data points
2. From the
correspondence compute a transformation
from model to
data
3. Apply the
transformation to the model features to
produce
transformed features
4. Compare the transformed model
features to the image
features to
verify or disprove the hypothesis
