Like the "profil settings" I mentioned in my first post above Setting some large deathzones to the curves in the beginning can be helpful. That is quite disconcerting in a first time and it needs a couple of hours to really accustom to it. You need to be aware also, that you do not have one to one movements, because you are multiplying them ingame.
What kind of daylight filter you are using on the PS3 cam? If you got jitter (JPS counter red) your cam are probably tracking more (or less) then three dots.
When they are bigger then reduce the point size: Please check if you got three dots with white crosses in the cam review that do not flicker when moving. Probably the cam settings.įreetrack works as good as TrackIR (I have both running on my PC, preferring Freetrack for the advanced settings and TrackIR for it's simplicity). This is definitely a problem of your settings.
Is this a hardware or software or clip fault? As a head tracking system, it's completely unusable anyway. To be honest I didn't actually realise just how bad it was until now, because in opentrack the figures reported are quite large, but in FreeTrack the X, Y and Z translation figures are in 1/100s of a mm which translate to noticeable movements on screen of course. I mean WTF? How? The light source is constant, everything is rock solid. I reset the view so that all the readings are 0,0,0,0,0 and the Z parameter (especially) just goes up and up by itself! I can occasionally even see the crosses moving on the 'cam' screen as a new position is being interpolated. The desk by the way is huge heavy solid pine effect. I just mounted the clip on a tripod again and set the camera on my desk (to eliminate monitor movement). With Freetrack it's almost impossible to move, look and 'maintain' that position. The Trackir system is rock steady, stable and accurate, unlike freetrack/Opentrack where the view is drifting/jumping/unstable. If you compare any number of Trackir4/5 videos on YouTube with my results, then it's like a day and night difference. I'm beginning to wonder if there is a fundamental flaw in the software in calculating the points? Either that or the camera is excessively 'noisy' leading to incorrect points being output? if that was the case though, it doesn't make sense because visually, the ONLY thing on the screen are the 3 tracking dots! I even mounted the clip on a tripod and the effect is still there. The problem is that there is 'jitter' irrespective of how still your head is. The points are being tracked absolutely fine. The dimensions of my clip are within a couple of mm exactly as per the reference model and the other dimensions have also been entered too with respect to the head model. I'm not sure what your point is (excuse the pun)? Has anyone apart from Luca actually (practically) TESTED the difference between a 3 LED Clip vs a 3/4 LED cap to verify if there really are noticeable differences in head stability / accuracy? The model is almost exactly the same dimensions as the reference model. I have used Freetrack 2.2 and the very latest alpha of opentrack (2.3 rc6) with all sorts of filtering and sensitivity adjustments, but it just isn't 'right'. I've tried 320 x 240 and 640 x 480 at all frame rates from 30-120 fps.
Tracking perfectly using USB powered SFH485P IR Leds. I'm using a PS3 eye with IR filter removed. I'm trying to get tracking working (properly) with IL-2 Sturmovik 1946, but I'm finding it almost impossible to keep my head stable enough to prevent jittery random movements. To be honest, I'm finding the whole thing a vast let down, but I'm wondering if it could simply be the cap/clip model that is the problem? Sorry to resurrect a really old thread, but I have recently built a 3 LED clip model and I am suffering HUGE problems with instability / sensitivity too.
