[ptx] Hugin: strange result after (trying to) make a panorama

[Claudio Soprano]

Hi Jean,

Important thing, is to use the optimizer.

What i do is

1) Creation of control points, usually i use autopano to do it , so it 
found lot of them

2) Run hugin and load the project, set an anchor image,  set an horizon 
(with control points) and do a simple pairwise optimize

2b) Do Preview to remove black borders and center the panorama

3) check for distances, and fix or remove (the really bad ones) control 
point long distance

4) Another optimize always pairwise

5) do step 3/4 up to get a really good low distances medium

6) Another Optimize for yqr

7) check for distances, and fix or remove (the really bad ones) control 
point long distance

8) do step 6/7 up to get a really good low distances medium

9) usually i dont do optimize for barrel distortion or view but if 
necessary u can do

10) do the panorama (cilindrical, multi tiff)

11) enblend the multi tiffs

this is how i create a panorama

hope can help u
