General Discussion / IR Camera Distortion
« on: July 09, 2008, 09:10:09 AM »
Does the camera return normalized undistorted IR dot positions ?
I would assume it doesn't and just return raw ccd processing results.
Did you hear of anybody who tried to compute the typical OpenCV calibration file for the wiimote camera ?

(You need a disto calibration file if you really want to get accurate position estimation)

Does the way the list of the (up to 4) tracked IR dots is returned by the library/wiimote follows any logic ?
Can I make any assumption like :

-- the wiimote tries to track them like keeping first found first in the list ?
or
-- they get sorted from left to right then top to bottom in the camera image ?
or
-- they are sorted by decreasing size
or
-- cannot make any assumtion, can be totally random, with a potential flip every frame...

Does the library/wiimote have any internal state that makes it remember a previous found dot to assign it again the same order.

My Config : Bluetooth USB Key : Belkin USB Key F8T013XX1 (that is what is written on the key)  with Belkin WIDCOMM driver version 5.1.0.3300
Windows XP. Dell Dimension 9200.

I, with pain succeded in connecting to my 2 wiimotes.
I ran my API that connected to both and it worked quite well.
The day after, it worked again.
So I wanted to test that I really had control over the whole process of bluetooth connection : big mistake !

Good Connection is indicated when the icons show a green arrow.

I disconnected the two wiimotes from bluetooth (deactivated the peripheral).
I removed the battery from one to be sure there was no bad interference.
And now, in the connection process, the green arrow appears only for a fraction of a second while selecting the service. The tray icon remains green a little longer, but this changes nothing.

Yes I tried to keep pressing 1+2, with no success.
I tried reinstalling the drivers with no success.
The batteries are Full.

And worst of all, I have now an info bubble that pops up over the tray icon 10sec after the failed process that says :

Personnal Bluetooth Code Mandatory.
The peripheral nintendo RVL-CNT-01 tries to connect to this computer. Click here to autorize the connection. To refuse,  discard this invite.

If I click on the bubble, a box appears. (here the french version)

It says "they have to be paired" blabla , OK/CANCEL/HELP...

Since I have no code, that leads me nowhere.
It really looks like over the count of connections, it was getting worse and worse. I mean : harder and harder to connect. I mean : the old one was harder to connect, then both, then the first got impossible, then the second one (Just an impression in the chaos).


Any Idea ?
