Question

Transforming a photo of a cylinder to a flat canvas

I am trying to extract a frieze ono a tower on a childs toy to reproduce it on a plane. 

I have 8 photos of the tower but would like to merge them to get a flat picture. I have seen tutorials on how to take a flat picture and wrap it around a cylinder but not the other way round - 

any advice ?

You haven't seen a solution to this because it is hard to do. You would need a scanner, scanning the object line per line, by turning a small amount each time. Or you will need to take numerous pictures of your tower and stitch the pictures together and compensate for the cylindrical distortion.

How about putting the object on a turntable, and using the Panorama feature of a smart phone (keeping the phone stationary).

That would be a great solution. I think, however, that my phone expects to move.

 

You surly need to put the subject on a turntable.
