Rules of Camera Tracking
Computer Arts has a free tutorial in pdf form entitled “The Rules of Camera Tracking.” It’s more of a tips and tricks of camera tracking, and though it makes mention of some commercial software, the overall guidance is sound.
Please… tell more about the Blender tracking script .))) I’m so lazy… just din’t wanna read a lot of manuals and all the stuff around that .)))
Thanks .)
Also worth noting is that a silver christmas ball is the perfect tool for setting the value of lights and building an envmap.
Just my 2Cents. :)
I haven’t had time to read the article, but fyi, there is free (but not open source) camera matchmover software called voodoo available at

It has the ability to export to Blender. I’ve fiddled with it a little and was pretty impressed.
I’ve done a little quick test with voodoo and blender (no greenscreen, but 3d on video)

It is very funny! :)
It’s easy to use, here is a quick sample:

A decent alternative to an actual green/blue screen is to use retroreflective material and surround your camera with a ring of LEDs. I’ve done some experiments with this and it works quite well, the advantage being that you don’t need to worry so much about lighting issues.
