Displacement Maps

I have several images of buildings that were stiched together from digital pictures taken from ground level. The vertical perspective of these images created a "smile" when the images were stitched. I think that if I could create the appropriate displacement maps, I could use a displacement filter to remove the smile and "square up" the stitched image. TIA

actually... if you took the photo properly, the panaranic photo taken will look nice.

Most Digital cameras have a built in for this...

Side,
Thanks for the reply, but what is important in these pictures is the building face, so that it can be applied to a 3-d digital model of the building. Each digital photograph was taken from a different point to minimize the horizontal perspective influence. I am sorry if I didn't make myself clear on what I am wanting to do.

meaning, you're using the picture as a texture/map for a 3d model?.. If that's the case... i can't really help..

Yes. That is what we are tying to do. Thanks anyway
