Topic: Coordinate mapping between different coordinate systems

Hi,

as far as I know the features recognition process can produce different clusters of points, each one expressed in a different coordinate system. This is because the synther is not always able to relate all the pictures together.
Is there any way to map the coordinates of a cluster into the coordinate system of a different one?
I think the answer is "no" for the reason above, but I may be wrong, so please, let me know if it is so.

Regards

@jediknight: Are you asking whether there is a way on photosynth.net to merge the separate coordinate systems or whether it is possible for external applications to do this?

There is no such function on the website, but I would imagine that if you are coding features for Meshlab that you are well aware that the smaller coordinate systems can all be losslessly scaled and rotated into the coordinates of the dominant point cloud. No one has yet provided such functionality, but being able to place the smaller reconstructions and single photos into the main coordinate system is one of the most requested Photosynth features of all time.

The last thing that I heard from the Photosynth team seemed to indicate that they were willing for others to provide such functionality, but they believed that their main demographic was so sold on automatic registration that they wouldn't have the patience for manual registration. There are plenty of us waiting for someone like you to provide a way to merge the pieces of a synth together in a single coordinate system, although ideally one would like to view the synth after the pieces are aligned and as yet I am not aware of how third-party tools could write the updated coordinates for the smaller clusters back to the Photosynth servers for the viewer to take advantage of.

For cross referential purposes, JediKnight also started a corresponding topic on the old forum which can also be checked for answers:
