<DIV id=yiv440265398>ICP only guarantees a local optimum, that is, if you start in a very bad initial relative pose, you will not find the "correct" (ie. global) solution you are looking for. You need to use another technique (ie. spin images) to initialize the ICP.<BR><BR clear=all>Thanks,<BR><BR>David<BR><BR><BR>

<DIV>Hi all vtk users.</DIV>
<DIV>I'm trying to make the registration of two 3D volumes using ICP. My problem is that, at their origianl positions, the volumes are opposed, so the result of ICP is wrong : i have 2 opposed volumes placed at the same refernce.</DIV>
<DIV>Can you tell me how to reverse one of the 2 volumes to have a correct result? It's an emergency.</DIV>
<DIV>Thank you</DIV></TD></TR></TBODY></TABLE><BR><BR>_______________________________________________<BR>Powered by <A href="http://www.kitware.com/" target=_blank rel=nofollow>www.kitware.com</A><BR><BR>Visit other Kitware open-source projects at <A href="http://www.kitware.com/opensource/opensource.html" target=_blank rel=nofollow>http://www.kitware.com/opensource/opensource.html</A><BR><BR>Please keep messages on-topic and check the VTK FAQ at: <A href="http://www.vtk.org/Wiki/VTK_FAQ" target=_blank rel=nofollow>http://www.vtk.org/Wiki/VTK_FAQ</A><BR><BR>Follow this link to subscribe/unsubscribe:<BR><A href="http://www.vtk.org/mailman/listinfo/vtkusers" target=_blank rel=nofollow>http://www.vtk.org/mailman/listinfo/vtkusers</A><BR><BR></BLOCKQUOTE></DIV><BR></DIV><BR>-----La pièce jointe associée suit-----<BR><BR>
