Hi, well I bought it without testing it properly -- used up the demo for the 2nd or 3rd time, changed from cameras to kinects. My bad.
Now I'm desperate.

Problem 1 (of two): When I try with either one or two kinects the floor plane is never right. It floats around camera height (0.9m or so) above the floor. Maybe it's supposed to, I don't know :(

If I drag the floor plane down using the pan/tilt button (under the Camera menu to the right of the mocap studio interface), and/or play around with the orbit control, I can bring the floor plane down to the 'right' height.
It doesn't seem to help.
Again I'm not sure if i should do this.

I've tried it both ways (i.e. leaving the floor up & dragging it down).

With one kinect the skeleton can be made to match, momentarily, but it then disappears once I start to move.

Problem 2: When I try to calibrate two kinects there's a sea of yellow, damn few green dots if any. It is quite hot here (> 30 degrees C) and I'm really hoping that's not part of the problem.

I've tried to post an image, hope it works...


As you can see, I don't know what I'm doing. Any help much appreciated.

Hi, sorry if I'm double posting, I seem to be having difficulty making a post.
I have a standard licence. Dual Kinnects. I'm desperate, I've spent 2 days on this so far -- and a substantial amount of money :)
My kinects do not set the floor plane to the correct height.
There may be other issues. I can't seem to callibrate.
I have read every post I could find and tried many fixes.
I have covered the floor and windows with sheets.
I have angled the Kinnects downward to see more floor.
I've tried various positions. Tried in the early morning when the temperature was lower (~25 C) in case that might help.
Any help or suggestion would be much appreciated thanks

Here's a picture... (haven't used dropbox before, hope this works)

Hello
Why do you think the calibration is incorrect?
Looking at the camera heights at your picture it seems they were determined quite ok.
However, don't know wether their directions are determined ok as well. Please attach a picture of your scene after calibration from the bird's eye, so both cameras ar visible.
Is the calibration board detected well? I.e. you can see in most frames green dots on its corners and in center after the calibration is complete.

Hint: you can attach images directly to posts.

Thanks for replying, vmaslov.
I thought the callibration wasn't any good because I couldn't seem to get the skeleton to match my own, or if I did then the skeleton jumped off screen as soon as I started moving.
The floor plane seems to go through my knees. On every demo I've seen the floor is underfoot.
So I thought that might be the problem.
The statistics to the right of the screen are correct, yes (but the floor still goes through my knees unless I move it manually).
Anyway, it'd be great if that was normal (maybe it is? :) I've just noticed that if I hold down the mouse button and follow the timeline post-callibration I can see the green dots and 'good' frames -- that might be a help.
Thanks for the upload tip too. I've attached 3 images of my efforts. I see the callibration stats have a good frame count of only 16 and a positional error of 2 centimetres (which I suppose isn't that bad).
Cheers

I think it's just optical illusion, because the floor is drawn as a grid and not as a solid surfrace, and camera looks from above the floor. Rotate the view to look horizontally from the floor's height (when floor's grid collapses into single horizontal line) - and you'll see wether actor's figure is indeed sinking under the floor.

Good frame count of 16 is absolutely bad. You need few hundreds of good frames for reliable calibration. First you should deal with this problem. Tips for you are:

• Hold the calibration plane more distant from your body.
• Do not rotate the calibration plane far away from any of the sensors, as it is shown on your screenshots. Better make its surface looking in the center area between the sensors most of the time.

Also I see much yellow noise in the images from the second sensor. Have you tried to make slight adjustments to its position/orientation to minimize this noise?

Thanks guys, your help has been invaluable. I followed all your suggestions and got a successful callibration -- 360 good frames -- (and without cleaning out the entire room or covering windows and floors to try and reduce shine). And during the hottest part of the day, so apparently that's got nothing to do with it either. Hey, apparently it's 4 degrees C in Moscow. Prediction for here is 39 C for tomorrow, 74% humidity. If I survive I'll try to find time to work on an actual motion capture.
Cheers
