| Subject: | ARToolKit with external pose estimator | ||
Hi, Using an external pose estimation system, how can I get the OpenGL graphics in ARToolKit to be correctly registered with the camera image? How can I get the scaling between the pose units of the pose system to OpenGL units? Thanks! |

Thanks Matt,
-that is almost all I need.
But what exactly is the "size", "s", or the "dist_factor[3]"?
I have understood that it is some sort of scaling factor, but how is it
calculated? In Wayne's paper from ART-02, it is 1.009989. Does this relate
somehow to the units used [mm] in real world?
When I calibrate the camera, if I enter [mm] as unit, will this reflect on
the "size"/"scale factor" parameter?
I have searched throught the mailinglist, and also checked out this
explanation:
http://www.sys.im.hiroshima-cu.ac.jp/people/kato/etc/distortion_factor.gif
, but I still haven't found a mathematical expression for this "size" or
"scale factor".
Thanks, anyone!!

Hi,
I'm not exactly sure what you are asking, but you might find
the following paper helpful:

Hello,
I wonder what the p factor is. Is it some kind of pinch-factor ?
