Description Anton V. Boyarshinov 2009-12-18 14:06:23 MSK
Предположительно после пересборки с libpano13 перестали находиться совпадающие контрольные точки.

APSCpp, enhanced autopano-sift-c version 2.5.2 23July2009 

  Default fisheye lens type is equal-area.
  Focal length will be computed from hfov.
  Stereographic projection enabled for hfov >= 65.0 degrees.

Connected component identification resulted in 2 components:

component 2: /dsc_3297.jpg

Warning: One or more components are not connected through control points.
         Optimization of the resulting PTO will not be possible without
         manual addition of control points between the components listed
         above. Please see the manual page for autopano(1) for details.

Файлы могу предоставить, но этот эффект наблюдается для всех опробованных мною парах и группах снимков, на которых раньше совпадающие контрольные точки находились десятками.
Comment 1 Anton V. Boyarshinov 2010-02-08 13:12:30 MSK
Согласно тому, что написано 
http://old.nabble.com/No-control-points-added-td27027401.html
необходимо собрать обратно 2.5.1 с serial. 2.5.2 сломан.
Comment 2 serpiph 2010-02-08 22:40:51 MSK
Собираю, а заодно и новую версию libpano13.

autopano-sift-C-1:2.5.1-alt1 -> sisyphus:

* Mon Feb 08 2010 Sergei Epiphanov <serpiph@altlinux> 1:2.5.1-alt1

- Revert to version 2.5.1 (r4054) due to bugs in keypoints (closes #22567)
