Updated panoramic stitching software

I’ve written fairly detailed reviews of Autopano Giga elsewhere, if you’re new to the software: V2.6, V3.0

The major features of V3.5 are listed (at Kolor) as:

  • New detection and validation engine. Not only the control points detection engine has been improved but it has also been automated. It means you don’t have to care about the detection settings anymore and the result is better than before.
  • New optimizer engine. The engine now selects far more control points in overlapping zones than in version 3.0. It also handles much better, any parallax errors and gives pixel-accurate stitching in most cases – in particular with lines (roofs, electrical lines).
  • Papywizard/VRDrive2 new import engine. The optimizer includes a new algorithm which gives a better grid and avoids orphan pictures while trying to respect the XML values: creating gigapixel panoramas with robotized head is easier

I’ve never had many issues with detection accuracy, even with hand held source images, but after trying V3.5 on a few sets of source images I noticed that there were less small glitches in the results that needed ‘fixing’ in Photoshop afterwards.

For a really big panorama, made with APG – see this about making a 14 metre print.

The view of Bodium castle was created from 7 source images – each from a 17mm lens. It was hand held, and in the past a few parallax errors crept in around the water’s edge. I’ve not post processed this image – the lighting is that flat (click to open larger version).

What were detection settings, are now set at automatic, by default.

Also added is a new ‘Fisheye’ projection.

The angle of view of the fisheye can be set – here at 180 degrees. You can see that my collection of shots did not fill a 180 degree FOV.

Reducing the FOV to 100 degrees shows a circular view.

I was wondering why you might need this projection? One use might be if you have software that makes use of fisheye images, then this is a way of creating extremely high resolution ones at much better quality that you’re ever likely to get from a single shot.

I’d note that it was the update to V3.5 that helped convince me to recently update my working Mac to OSX 10.9, since it no longer worked on my old 10.6 system.
