I am sure many people has beeing looking for ways to match holograms to real world objects accurately. The Lowes Kitchen demo shows a really good example of this and they recently put up 2 videos about how they did it. In part 2 it shows how they did the precision alignment. you can see from below screenshots from the video. They used image trackers ( a few ) and some kind of 2/3 point alignment system to get the hologram locked in place. Any anyone shed some light on how this is done ?
