does anyone know of a way in pix4d or other software to generate a planar ortho from a cylindrical surface such as a round water tank or chimmey?
thanks

you cannot generate 1 ortho out of a cylindrical surface with Pix4Dmapper. You could use the orthoplanetool to generate smaller orthos of each side of the cylinder. To be honest, I do not believe this will cover your needs, as the development of the cylinder side in the ortho would not be accurate, it would be as if it was a planar side.
Maybe other users can recommend a 3rd party software. I am also interested in knowing more about it 
Thanks getting back to me.
I’m leaning towards the concept of generating orthoplane about every 15 degrees around the object and them merging them into one image.
I have tried cloudcompare software. but it will only unroll to point cloud. I’m also looking onto FARO photoplan.

Let me know about the results!! I am curious!
Ok I will.
Me too!
Interesting!
