i have some annoying behaviour i've been trying to find a cure for (pre-built 6050 in the black box with the sexeh USB cable). when i look at a UI screen, say for 10 seconds, then look forward again my view is not centred, it's too far to the side of the UI screen i was looking at. this happens either side.
i've let my EDTracker stabilise for 30 mins during the calibration process (EETracker2Calib 2.5.3), those dots are now nicely lined up and the gyro numbers stayed stable with the accel numbers fluctuation by 1, maybe 2. i left it running another 15 mins once calibrated and this behaviour stayed constant so i assumed that was as good as it was going to get.
i took a similar approach to letting the drift compensation run it's calculations (EDTracker2 2.20.7), left it wedged between 2 books. after i saved the value i let it run again to see if it would change. it started out at 0.05 difference then that gradually went down to 0.02 so i called that stable enough. i then pinned it in place with some constant pitch to see if it would drift, which it didn't as i was wondering earlier if the pitch my headset puts it at would mess with the drift compensation.
my temps are annoying, on the bench it's at 27 deg, on my head it's at 32 deg, so i'm aware i cannot get a perfect calibration.
that said i seem to have eliminated the drift issue i had initially (recentre set to strong and GUI minimised), time spent calibrating really does pay off!
so it's just left me with this habit of not going back to centre after i've looked to the side for a while
i'm using opentrack 2.3rc5, joystick as input, EDTracker2 selected and i've had to map yaw to #2, pitch to #3 and roll to #4. i believe these differ from the tutorial but with a bit of messing about on the bench tilting it one way then the other it seemed clear this is the way i needed them assigned. i'm using freetrack with only show trackir. i'm using accela with smoothing to the min and noise reduction at low. it makes things a little rough but i decided to stick with data closer to raw to get a better feeling of what was happening. the spike noise smooths out just enough for it to be playable.
on mappings i map yaw of 40 to 180, pitch of 40 to 180 and the rest are pinned at zero. i have a 27inch screen so get to look about a fair bit. i disabled translation compensation but that didn't seem to make any difference (no surprise there, it's only getting info for 3DoF)
after about 1 hrs flight time bumbling about looking for pirates it was behaving impeccably, but when i'm flying like that i don't use my UI screens for very long. by the time i finally docked the station UI was nice and centred. so it looks like i've got things working well, starting to feel better than my LED tracking (with a bonus i can look up and behind more in my ASP
).
so i'm not sure why it wont centre if i've been looking to the side. i noticed it when coming out of the fittings screen as i'd been looking at the left side of the screen mostly. i notice it after selecting a nav target while in station. it's really bad if i look at my 2nd monitor to read the forums etc, at times i'd get back in game and my ahead view was looking at the UI!
so is this some inherent limitation in the hardware? is there some tweakage i can do? i'm no hardware guru but i have messed with serial components before (they let me play with a frickin laser! i then had to use it to write some distance logging software). so i'm happy to get my hands dirty so to speak.
i've played with both LED tracking and the mobile phone free solution. the EDTracker knocks the socks off my phone, i had to turn it off as soon as i'd landed, but after getting a taste for it i couldn't fly without it! despite having an EDTracker on order i went and got an LED tracker too so i could get an upgrade from the phone. i was still looking forward to the EDTracker because it has a much finer degree of accuracy (LED is limited by the 640 resolution on the sony webcam). now that i have it working it's got a better feel to it than the LED does. i was also a bit surprised to find the LED tracking isn't much better at the return to centre thing, so could it be some limitation in the tracking software? i've tried both opentrack and freetracknoir for the LED, both had issues recentering though mostly after looking at my second monitor. i didn't notice it when looking at the UI screens.
if there is no fix to this then it's not a show stopper, i've got it to a perfectly workable point, just looking to get rid of the remaining niggles.
