Just like Bruce Forsyth's wig
I can see the join...
There are quite a few apps that can be used to stitch together a series of overlapping photos in order to create a single, wide-angle panoramic picture. These apps all use clever algorithms to try to line up elements within the photos in order to create a seamless overlap, but even the smartest software can’t do much to help if …
Given the poor quality of the produced panoramas (discontinuous kerb slopes, blurring of bricks and windows) I'm surprised this gets 80%. It seems to me that the devs are using the gyroscope as a hack to help them fix a poor-quality seaming algorithm. Considering what could be done with a proper understanding of the mapping from pixel to ray and using the gyroscope and accelerometer data to improve the matching process (i.e. SLAM), this seems like more of a novelty item.
There are dozens of panorama apps on the iPhone which achieve similar quality, and most of them are free.
Might be a clever app but the panoramas are awful.
Try AutoStitch Panorama -- you don't need to hold the phone any special way, just snap away overlapping in vertical and horizontal orientation just as you like, even in several rows, and it will analyze and stitch the photos together. Creates much better panoramas with even less bother while taking the photos.
And that's the cheapest Fuji pocket camera in the shop. It uses image tracking to place a cross on the scene that tracks around as you move the camera. When you line it up with a fixed circle on the display it takes the next shot. Sometimes it screws up but mostly it does an excellent stitching job.
I found Autostitch a pain as it doesn't let you provide hints. Photosynth is unpleasant to use. Best one I've found is PhotoStitch, that comes bundled with Canon cameras.
