| Post subject: | Figuring out Kinect |
Hi Folks, with 4 days left on the trial I have abandoned trying to use ps3 cameras and have now got a kinect camera. So when I stand in front of the camera, in order to get my whole body in shot I have to step back so far that in the rgb rendering I merge with the backround Is there some trick to operating the kinect so that I can switch it from zoom to wide angle? I thought they would be wider angle than the PS3 ones but I'm not experiencing that in practice. My first few refit poses have the actor flying off the top of the screen. Thanks AaronC |

Nevermind, I just got my first clean capture :-) Happy Chappy |

Glad you got it working! Yeah, single Kinect should be straightforward--it's pretty much plug-and-play with no calibration involved, and it works even modest laptop computers. You just need make sure you have a few seconds of clean BG video in your captures. When I was testing it, I found that results can actually be quite good if you tailor your performances to avoid occlusion issues. (FYI, a couple of shots in Happy Box were recorded using single Kinect.) Tip: If space is that limited, try putting the Kinect in a corner of the room to maximize distance. Alternatively, you could put it behind a doorway. Let me know how that works for you. We've been using the twin Kinect configuration in our living room which is just big enough to do a full 90 degree setup without moving the furniture around too much, but I think we might be able to manage the 180 setup if I put one of the Kinects in the adjoining computer room and shoot through the doorway. FYI, the 90 degree setup works really well for many complex actions--I can even capture up to four steps for walk/run loops with it. But for certain motions, occlusion can be a problem sometimes (wide and wild arm swinging, for example,) so I may need to do a couple of shots with the 180 setup. As for PS3 Eye cameras, it sounds like you barely have enough space to use a single Kinect so, yeah, using the PS3 Eye configuration is going to be tough in that space. Sorry that didn't work out for you. It's a very good system for capturing big and complex motions but you need a fairly large space to make the best use of it. For example, I have this config set up in a two-car garage and that's still not big enough for a full circle. I may wind up using it in the backyard just for special situations where the Kinect setup is inadequate. G. |
