Hi everybody, I was wandering if someone has come to a solution for point cloud scaling to real coordinate different (one could say shorter) from this http://www.personal.psu.edu/nmc15/blogs/anthspace/2010/02/structure-from-motion-point-clouds-to-real-world-coordinates.html
Thank you in advance for your help!

I can't say that I have too much experience with this, but I can point you to some other discussions on the subject.

In addition to Nathan Craig ( http://photosynth.net/userprofilepage.aspx?user=Nathan.Craig )'s article above, he also wrote a follow up about changing the decimal place to optimize 3D performance.

Mark Willis ( http://photosynth.net/userprofilepage.aspx?user=sir_ivar ) also wrote up a workflow:

Jorn Anke ( http://photosynth.net/userprofilepage.aspx?user=brakar ) also began work on developing a bit of software for this.

Work seems to have stopped, from what I can see, but the source code appears to be available for download.

John Ellis reported working on a pipeline for this process as well.

This PDF talks a little about point cloud orientation:

My only other advice is to ask over at the Photogrammetry Forum: http://pgrammetry.com/
