Photosynth App Panorama problems -

This is regarding the Photosynth app for iPhones (which is different than the Photosynth computer thing that takes a bunch of images and organizes them in a 3D space. The app just stitches panoramas. It's almost really great at it).

Here's the problem: As I rotate through 360 degrees, taking photos as I go, the app gets back to the first photo before I do. That is to say, after I've turned about 3/4 of a circle, the app thinks I've gone in a complete circle, and tries to stitch back to the first photo again.

I've rotated the device around the lens, made sure there was plenty of light, and stood in a large space with lots of detail. All of these tricks made better stitched photos, but none of them fixed the problem.

In another comment thread from four years ago, Microsoft employee, Ken, said about the non-app version:
"If you know ahead of time that it's a 360 degree panorama you could take one of several approaches to make sure the last two photos align. This is what panorama software does."

But the Photosynth panaorama app doesn't do anything to make sure the last two photos align. It would be helpful to be able to tell the app, "Don't connect yet." Or to define a 360 degree space. Or I'm sure there's other solutions. I just need one.

Thanks very much!!

Hi there! I'm not from the Photosynth team - just an end user like yourself.

What version of the app are you using, LEGO?
Also, what device are you using and which version of iOS are you using?

If you have access to a Windows computer, you could try just using your iDevice's camera app to take photos and then using the free Microsoft ICE to stitch the panorama and upload it to your Photosynth.net account. This will result in higher resolution panoramas anyway.

...

I wish that I had a solution for you, but there aren't any settings or options in the app accessible to the end user that could affect this problem and plenty of other people use it to shoot 360 degree panoramas, so I'm not sure what to tell you there.

There shouldn't be any 'trick' to get the app to correctly shoot 360 degrees. For most people, it just does it right.

Aha. It seems to be an iPad problem. I just used my son's iPod, and it worked with no problem, so I know it's not my technique or the environment.

I'm using 1.1.3 on an iPad 2 running iOS 5.1, but it didn't seem to work right under 5.0 either.

Maybe it's something with the iPad's accellerometer. I'll give AppleCare a call and see if they have any ideas.

I know there's ways to jigger around the problem, but its not nearly impressive of a demonstration when I take a dozen photos and then tell someone, "Now when I get home, I'll stitch them together."

Also: harder to be sure I'm getting full coverage for a spherical panorama.

Thanks for the reply. I'll also try looking at those other forums.
