I need to align two data sets in OSG by fitting a small number of key points and calculating the translation/rotation matrices.
Normally this is done with a Helmert transform, that defines 7 parameters (xyz translate, xyz rotate, linear scale) to convert between map coordinates. GDAL seems to use Affine transforms instead - it has routine to apply transforms but I can't find anything to calculate them. First has anyone else already done this? Second - since it's going to involve pulling in a lot of Least-Squares/SVD or other solver code is there a preferred numerical library?
