Hi guys,

I'm looking into calibrating a projection onto a curved surface and I was wondering if someone could point out some useful software to do that!

Thanks

Welcome to the forum. You have not provided nearly enough information about your setup. Please elaborate on the equipment you are using and the other conditions involved. What is your specific objective?

Thank you for the prompt answer!

I have ACER s5201 projectors (i actually have 4 of those) and one benq mp777, as far as the lighting goes, it will be controlled environment so that wont be an issue

The idea is to have an interactive yoga studio (individual for now) and I'm currently developing the mat itself, using microcontrollers and force sensing resistors.

On the screen side, the idea is to have it rear projected and a curvature yet to be defined...for a quick prototype i would just use a wood frame and white fabric, just to have a better feeling of what i want as a final result



Thank you!

There are digital image processors designed to manipulate the video signal so that it aligns the picture with an irregular surface. I have never used one. They are probably pretty pricey. Try this for a start: http://www.bing.com/search?q=geometr...or&form=OSDSRC .

i will look into it...but isn't it possible to do it via software by mapping the projection area or something similar?

After following the link you gave me, i ran into the pixelwix software website, not sure if it's a possiblity or not....i am ok with buying a processor, i just would like to have a better idea of the result first
