Camera calibration

Hello everyone,

I have two questions concerning the camera (Logitech 3000 Pro).
I am using 2.52 on a PC.

1. The image is reversed left<->right.  How do I correct this
   without recompiling code?

2. I am finding it difficult to run calib_dist because the mouse
   pointer is rarely visible, because of camera refresh or something.
   Any suggestions?

Also, does anyone have tips for mounting the camera and the goggles
(i-glasses) as a single unit?  Thanks!

Regards,

David K. Drum

Try checking the "Flip Image Horizontal" box on the camera dialog box that opens when ARToolKit starts. > 2.

If you break open the Logitech 3000 camera the circuit board inside is pretty small. Put this into a cheap plastic box and velcro or glue it to the head mounted display. Hope this helps..

If you are using Windows try changing your mouse pointer to the default one (white without shadows) . It works for some OpenGL programs. ---------------------- Andrés Yovanny Agudelo Toro VR LAB EAFIT University

I went to Start->Settings->Control Panel->Mouse->Pointers and discovered that I am using the "(None)" scheme. I detected no change when I tried the "Windows Default" scheme. Thanks for the suggestion. Regards, David K. Drum david@m .......

That box is shaded out. I am using the ARToolKit2.52 Software with VRML support [7.7mb] (Windows Direct Show Version with OpenVRML rendering) from the download site. Is that the best one to use?
