I'm interested if there are some sweet open source software (or if ArcMap/ArcScene can magically do it) that can help me georeference point cloud data. I have been using Microsoft's Photosynth to get my point clouds- but have been hitting a wall to try to get it to a point I can do some measurements with it, or just at least add it to ArcScene/ArcGlobe. Thanks!
Not an expert on this topic, but I was checking out this report. The author names a few software sets you might want to look into in section3.
