'[OT] Panoramic scene stitch tool for digital photo'
2005\04\13@231920 by Dwayne Reid

Good day to all. Russell's comments about the scenery in Arizona and Fred Langa's latest newsletter both occurred today - and are vaguely related. Fred tells of a fully functional software demo that will stitch multiple digital photos together to make a large panoramic composite. The sample shown on the website originated as 56 individual photos and looks stunning. From his newsletter: Hi Fred: I recently came across a very impressive technological advance and tool, which can bring panoramic photography within reach of anyone with a digital camera. The tool is called AutoStitch and can be found at www.cs.ubc.ca/~mbrown/autostitch/autostitch.html Actually, the download is a development prototype demo, not a finished product by any means, but to the extent that I've used it, it works as described on the website. The program automatically discovers and 'stitches' together overlapping photos from a group of photos, and creates a panoramic output file. It can combine photos horizontally and vertically. It requires no installation, and the single executable is quite small (~700kb), considering what it does. The demo has a very simple user interface (except for the options, which can be ignored). It has three basic steps, select the input file group, display the options from the initial calculations, and calculate and produce the output image (pano.jpg in the same directory as the input). It takes only a few minutes to execute on a 300MHz CPU. The options screen is mainly for development, but one option which might be useful controls the output file size. As a test, I stood against one wall of a room and photographed the other three walls in a group of eight photos, four including part of the ceiling and four including part of the floor. The program stitched these photos together seamlessly, and the result had surprisingly little barrel distortion. Check out the web site, but those with a dial-up connection should be prepared to spend a lot of time there - it's mostly all graphics. The Research page provides more technical details, and points to two documentation downloads - a slide presentation and a technical paper, both of which require a degree in advanced mathematics to understand. There seems to be only two major requirements in taking the photos - they must overlap and they must be taken from a single point of view. The process will even work if some of the photos were taken with slightly different zoom settings! I find it all rather amazing, and I'd like to see this functionality included in every digital photo workbench out there. Looking forward to the next issue.--Tom Mighill Wow--- you're right, Tom, this is impressive. This tool lets your PC do what used to take a supercomputer and a roomful of highly-skilled technicians. Amazing! <end of copy> BTW - I've previously quoted material from Fred Langa's excellent newsletter but neglected to provide links. Check it out at <http://www.langa.com> & <http://www.langalist.com>. He has both a free and subscription version of the newsletter available.

Brilliant Fantastic Rave rave rave .... If anyone wants a 1.1 MB 360 degree panorama of Meteor Crater made from 16 of my photos using this software look here http://others.servebeer.com/temp/MeteorCraterPanorama.jpg Not perfect but amazing considering. No user input apart from supplying photos. View at full screen HEIGHT with eg Irfanview and pan. Viewing full screen width looks only so so. If anyone has trouble downloading this picture please advise. I note some downloads of some files report less than full size files. Don't know why. RM

My own camera (Canon S50) will do stitching for you when you take a group of photos like this, but not with anything like this quality! Just one query: what are the blobs "above" the building in the second slice from the right? Cheers, Howard Winter St.Albans, England

It's not perfect. The blobs have no obvious source and no obvious reason for being there given that most other places are OK. There's one similar effect somewhere else but less obvious. It could be due to a very large overlap at that point between several images. The picture is significantly imperfect in a number of other places that are not obvious if you don't have the originals. There are 3 original marker posts on the left rim but 5 AFAIK in the panorama. Some of the paving ends far too abruptly in the panorama. I imagine that looking at the originals would give some clue as to why and help cropping etc of originals. This was a rather demanding merge as there was substantial overlap and some change in rotation etc. RM

A month late and a dollar long. Last month I spent several days stitching together ~150 hi-res topo maps into one monster 8500 pixel square image. I'm certain this would have worked it out in a few minutes. Sigh. Mike H.

A number of good map companies exist, but the maps provided by the USGS online are of a greater resolution. The result was a 14.5 MB beast which is quite huge. I should be able to crop it down pretty neatly to the areas of interest to me on this trip. Although the more that I think about it, a waterproof Fisher map might be the better way to go, anyway.

Russell, Russell McMahon wrote: > About 1 mile / 1.6 km across. > Far steeper and deeper than may seem in photo. Yes, much larger than it looks in the photo. I was there in about 1970 and hiked down to the drilling rig in the center. Went back about 1984 and by then they had stopped allowing non employees to climb down in. Apparently some lady tried it in heels and their insurance company said 'no more'. Have they begun allowing people back down since then? It seemed to me that a stairway wouldn't have been that hard to install. No trouble downloading it but had to use something other than my browser to view it. Thanks, Dave

Some more panoramas using Autostitch if anyone interested at http://others.servebeer.com/panoramas NZ shots only. Aim is to demonstrate the tool at work - photos are secondary. Some are LARGE. Try a small one first to see if download speed suits you. MUST be viewed at greater than full screen to be useful. Zoom to about full height and then pan left/right. Foodhall has the same people appearing in multiple shots (my wife / daughter / friend). Church interior shows how useful panorama can be for fisheye type interior shots - and limitations. Rendering of this image using full size 5MP image input was over an hour on Celeron 1800. Much faster at lower image sizes. Marvellous free (so far) Autostitch here http://www.cs.ubc.ca/~mbrown/autostitch/autostitch.html I did an interesting 360 degree panorama in a friends lounge with 4 children as willing participants. Photo NOT available on web. For each photo I pointed to where I wanted the children to be and they arranged themselves casually in the general area - sat on chairs, floor, steps, leaned on walls etc. Resultant panorama has 40+ children in the room. Numerous ghosts too. These can be reduced by cropping source photos so areas where figures are and aren't don't appear in adjacent shots. RM

> I noticed on the church image how people on the edge of the > individual > image who move become transparent if that is a good term. Yes - "ghosts". The program sees basically identical scenes in two shots but with minor differences caused by movement. It has to decide how to meld these dissimilarities. Sometimes it duplicates things (Meteor Crater marker posts) or removes them (Lounge - picture not available). Algorithms would be interesting. RM

My daughter is cooperatively hamming it up with different poses in each group. She's a natural at getting into the spirit of such things. RM

That was the point. Thai, Kabobs... and I've never seen sushi in a food court. McDonald's and their ilk is the most common. I quoted "food hall" primarily because that was the name of the panorama file and only partially because the term isn't used in my part of the world. Bradley
