[Insight-users] ICP example data

[Bing Jian]

Hi,
   In Insight/Examples/Data, there are two files:
     IterativeClosestPointFixedPoints2.txt
     IterativeClosestPointMovingPoints2.txt
containing two 3D point sets for testing the ICP algorithm implemented in
ITK.
I would like to know some additional information about this dataset,
like who originally contributed this dataset and where were these points
extracted from.

The result I got from running IterativeClosestPoint2 on this dataset is
Solution = [-1.72668, -0.0894016, -2.74065, 81.0172, -312.198, -430.148]
The equivalent rotation matrix from the Euler angles is
[ -0.882593306250847  -0.060593182245878   0.466216175209009
  -0.469932886152806   0.142940536523386  -0.871051712317070
  -0.013861395070245  -0.987874723476476  -0.154633089741434 ]

I also saved the transformed moving point set but it seems not very
well aligned with the fixed point set.  Is there any ground truth
transformation for this data?

Thanks,
Bing
