I am producing a video documentary about wrecks and I have to build many photo mosaics, by stitching a lot of still pics from each underwater wreck photos or video frames.
Pictures was taken from constant altitude above the wreck ceilling and are not wide (not fish-eye)angle.
Does the PF can auto-stitch many pics to build up a multi-row and multi-column linear photo-mosaic? If so how?
(One sample that what I pretend is like the wreck mosaic:http://www.shipwreckcentral.com/livedive/archives/2006/02/
Thank you,
Sincerely,

Although The Panorama Factory was not designed for this type of stitching, it is possible to use it for photo mosaics.
Interestingly, one of our users, Stephen Breitstein, has also used it for single-row mosaics of underwater shipwrecks. He has posted several examples in our User's Gallery:
Byzantine wreck, Dor 2001/1, uncropped
Byzantine wreck, Dor 2001/1, cropped
Byzantine wreck, Dor 2001/1, uncropped
Byzantine wreck, Dor 2001/1, cropped
Byzantine wreck, Dor 2001/1, Side View
Byzantine wreck, Dor 2001/1, General View
For additional information, read Notes on Stephen Breitstein's underwater mosaics.
These are all linear mosaics. But it is also possible to use a multi-step procedure to make two-dimensional mosaics. The general approach is to stitch each row of photos into a linear mosaic and then join the rows together after rotating them 90 degrees.
The web page Multi-row stitching with The Panorama Factory V4 describes this multi-step procedure used for conventional panoramas.
For photos taken from constant altitude above the wreck ceiling you will probably get best results using The Panorama Factory's "Manual Document Stitching" method rather than any of the automatic or semi-automatic "Photo Stitching" methods. The "Manual Document Stitching" method disables image warping. It's probably best to disable warping because it is designed for photos taken with a rotating camera from a fixed point.
