      you are using the autopano plugin inside ptgui to create control points?

      not sure why you'd want to do that. it's about 4 years old - quite slow and out of date by now. the ptgui control point generator is much (10x ?) faster and otherwise better.

      you can also try the autopano pro software, which sometimes does a better job guessing the unknown positions of images.

      if your images "Not all of them have many details" as you say, then you might need to make manual control points yourself - in that case ptgui is easier to use IMO.
