[ARToolKit] problem running ARToolKitPlus on PC (win xp sp2)

Hi everyone,
I use ARTKt+ (ARToolKitPlus_2.1.1) for my AR project
on HP 64-bit-system (vs 2005 on xp with sp2). One of
my
modelviewmatrix is below :
-0.95  0.05  0.29  0.00
0.17   0.90  0.40  0.00
-0.25  0.43 -0.87  0.00
88.45 36.18 440.88 1.00

and distFactor 265.00 185.00 20.60 1.01
camsize (640, 480)

My problem is that when I mov my cam, the virtual
object follow it and it's cause the misalignment of
real image and virtual
object. but it's work fine on my PDA (I use the same
camera file : camera_para.dat). Is someone have an
idea ? on my PC I use OPenCV for grabbing frame.
many thanks

Your PC's camera has different intrinsic parameters than your PDA's camera (most notably the focal length). If you want precise results you'll have to calibrate your PC camera too...
