Camera/Projector calibration

Hi,

First post so go easy; very new to computer vision too.

I need to calibrate a camera/projector system such that I know where each pixel of the projector is going to project to up to maybe 30 degrees offset either way from perpendicular to projection space and at any distance or orientation.

I believe this is called projector calibration.

What are the current start of the art techniques for this? and what sort of accuracy are they able to achieve? Any links to papers to read would be nice.

What are the "perfect" conditions for calibration/demonstration? (To aim for)

Thanks.
