Wiimote Blob issue. {Enhancement} #9

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
I'M using the wiimote method, the LEDs blobs are shown varies from 2 sizes, big 
and small. They are both changing frequently, and it affects the output. Is 
there any smooth feature, or ignore the blob sizes settings?

Thank you! I appreciate any help.

Regards,
Talal

Hi Talal,
actually on wiimote the size of blob is not used at all, because wiimote 
returns position of blobs by itself and the blob size is used only for 
displaying to give user a clue of what does it see.

To smooth the tracking, you can try to set a bit higher filter factor in the 
tracking setup.
Kind regards,

Michal

Thank you! 

I switched over using Webcam, and use the wiimote IR filter (background) so the 
webcam can only see the blobs as usual. However, the wiimote implementation 
isn't stable at all. I also noticed my leds are a bit low. But i can use 
FreeTrack with wiimote working like a charm.

{Implementing the linux-track-wine.)
However, thank you so much for providing such a needful software.

Talal

Hi Talal,
may I ask you what exactly do you mean by saying "wiimote implementation isn't 
stable"?
Is the software crashing? Or do you mean the stability of tracking?

The problem of wiimote is, that it does the blob tracking all by itself, giving 
you up to four blob coordinates; it also means that there is no way to weak the 
process (setting thresholds and stuff). What it also means is, that if wiimote 
sees more than 4 IR sources, it may just choose arbitrarily between them, 
effectively ruining the tracking. What I'd advise (unless you meant linuxtrack 
was really crashing) is to find a movement, that causes tracking to jump and to 
see in the camera view, if there isn't something funny going on (not sure how 
about wiimote, but even indirect sunlight does bad things to track ir). Maybe 
you see other blob popping up, or a blob jumping between two places or 
something similar...

And what do you mean by "{Implementing the linux-track-wine.)"?

Thank you for the feedback,

Michal

Sorry for misunderstanding, i meant like, it isn't supported.

And i have recently tried it on Freetrack, and it worked great.
linux-track-wine project to be able to use it in IL2, i know, i can use the 
ltr_pipe, but it didn't work as 6dof, and of coarse using the 6dof mod. (+ 
thats because it uses DeviceLink). Got the webcam running at 30 fps (before=5) 
after some tweaking in v4l etc... However, thank you for response. 

Sorry for the vague description.

Regards,
Talal

Linuxtrack wine bridge is part of the latest universal package.
Feel free to reopen the ticket if needed or open a new one.
Kind regards,

Michal
