I am currently developing an application using ARToolkit under Windows 
and am encountering disparities in perspective between virtual and real 
objects due to differences between the camera distortion parameters 
stored in the default (distributed) camera_para.dat file and the 
characteristics of the camera I am using.

Unfortunately the two programs used to generate new camera parameters 
only seem to be distributed for Linux or SGI versions of the ARToolkit, 
and the camera I am using will not operate on these platforms (the 
reason why I am using the windows development platform).

If anyone has a version of calib_dist and calib_cparam for Windows I 
would be very interested in hearing from you, otherwise I will have to 
embark on the conversion of these programs from Linux to win32. 
Otherwise, if anyone has the camera parameters for the Orangemicro iBot 
firewire camera this would also allow me to avoid this task.

Thanks,

I put a new version of ARToolKit at:
http://www.sys.im.hiroshima-cu.ac.jp/people/kato/etc/ARToolKit2.43.tar.gz
http://www.sys.im.hiroshima-cu.ac.jp/people/kato/etc/ARToolKit2.43-Win32.ZIP

This version of ARTolKit works on Linux, Irix and Windows.
ARToolKit2.43.tar.gz is a tar+gzip file (70k) of source codes for all platforms.
ARToolKit2.43-Win32.ZIP is a ZIP file (14M) with windows binary codes.

I have just made them. So there might be some bugs in it.
Please let me know about them if you will find.

Hi,

Has anyone using ARToolkit under Linux got it to work with a firewire video
device (i.e. using /dev/raw1394 instead of /dev/video in the ARToolkit video
library?) 

We are looking into this for running live video firewire input to our
laptop, running Linux Redhat 7.1, since its potentially faster than USB
camera input.

Also, anyone using Firewire live video input under Windows at this point?

Thanks, -Randy

There was some bugs in ARToolKit2.43.
I fixed them and put them at:

http://www.sys.im.hiroshima-cu.ac.jp/people/kato/etc/ARToolKit2.431.tar.gz
http://www.sys.im.hiroshima-cu.ac.jp/people/kato/etc/ARToolKit2.431-Win32.ZIP

I mode a new example code 'modeTest'.
You can check the performance of ARToolKit for each mode.

Graphics Mode:
   glDrawPixels, texture mapping(half res) or texture mapping(full res)
Image processing mode:
   full(frame) image or half(field) image
Fitting Mode:
   compensated image or input image
