Hello Anat & all
First of all thanks for all the great work on that 1.5 release! It’s a pleasure to work with it…especially with a multicam setup.
I just used it for setup with 4 cams recently and run into a strange problem when using fiducials.
Details of the setup:
- Windows7 x64
- Codelaberatories driver
- 4x activated eyefi (2x2 setup), cams running at 640x480px, 60fps each, multiplexer set to 1280x960px
- DSI surface
What I’m trying to do is to track fingers and fiducials at the same time. Everything with the setup works fine and finger tracking is great, but the fiducials don’t work reliable. I also tried with a fiducial of gigantic size, so it’s clearly well visible in the camera image and I also made sure it’s in the middle of one of the cams, so not a stitching problem either.
The fiducial would get recognised for some frames (green frame around it appearing in the preview), but then it will lose it for a few frames (green frame jumps to some position on the left top of the interface…outside the cam preview!!). So it’s constantly flickering….also the coordinates I get on the other end of the TUIO switch between: correct data, some wrong (random?) coordinate and a few lost frames.
Having experienced this, I went back to only using 1 cam, and Fiducial tracking was fine. Then I set up the 2x2 cams again and found out, that the fiducial flickering gets worse the higher I set the resolution for the multiplexer?!? If I leave the multiplexer setting at 640x480px it only flickers occasionally (and green reference frame does not appear anywhere else in the interface)…when setting back to 1280x960px the flickering started (plus green frame jumping to that position on the interface).
Is this a known bug? Anyone else experienced this before? Or does anyone have an idea about what I could have done wrong?
Any help appreciated…
