Tutorial: Panoramic photos with autostitch

Developed by Matthew Brown and David G. Lowe, autostitch is a software tool for creating panoramas. It is proprietary, but free to download and use. The only restriction is that you must acknowledge that you used autostitch for your panoramic photos.

In this article, I will try to explain how to use autostitch to create 360-degree panoramic images.

First of all, you must take your photos. I found that it is easier to stitch when the photos were taken in portrait (i.e. vertical) mode. Here you can see the images I used for this panorama:



Note that the photos cover more than 360-degrees. The photo IMG_2821.JPG is almost the same as IMG_2823.JPG. That is why my first photo will be IMG_2821.JPG, and the last one IMG_2837.JPG (because they partly overlaps).

Neighbor photos must overlap. And the bigger the overlapping area -- the easier will be to stitch them together:



When you download and unzip autostich, you just have to start autostitch.exe. Autostitch works fine even on linux (I tried it on Ubuntu 6.10 with wine).

This is how it looks like:



Next thing is to tell autostitch about the width of your panorama. Select Edit->Options and select your desired with in the in the field Width (pixels). Default value is 1400px. I usually choose 5000 or 6000 pixels:



Click OK, and then File->Open and then select your images:



When selected autostitch will automatically start the stitching process:



When stitching is finished -- autostitch will create a pano.jpg image in the same directory:



As you see - pano.jpg have those black areas at the top and bottom. You must crop them out... Here is how to do it with GIMP:



But you can use any other photo-processing software...

And then you can play with the saturation, contrast, color balance, and similar options... And here is the result:

This is how I make my panoramas. But, I'm a programmer, not a professional photographer and there are many subleties I don't know. Feel free to comment on how to make this tutorial better!

Login bug

Given enough eyeballs, all bugs are shallow
It means that if enough people is testing some (software) application -- they will find every bug in it.

Since panoye is still beta (and it will remain beta for some time ;), there are bugs. The latest of this bugs prevented some users to log-on the site... After they typed their username and password -- the response was:



Thanks to teothx who found and alerted me about this error. Grazie mille!

I changed position of the "Reply" textarea (from bottom to top-right). Also, now it have a "Preview" button.

For all early adopters of new technologies (like RSS readers ;) - panoye.com now have two new RSS feeds: one for the latest panorama comments and one for forum posts.

That's all folks (for this week ;)

Forum, profile images, orientation

Profile images

Maybe you already noticed it, but now you can upload a small image that will be shown on your profile page. Here's mine:

Forums

Added the forums section on panoye.

I wanted them to be as simple as possible. Without too much (rarely used) fancy features. It sill lacks a few options (RSS, basic formatings), but it will be online soon. (here is a sample thread)

Partial panorama orientation

Now orientate partial panoramas should be easier. Instead of locating two hotspots on the panorama -- you have to find the directions of the panorama's visible field; first the left side of the panorama's visible field, and then the right side. I'll write a HOW-TO article on the forum about this (when I find time).

Features, updates, bugs...

A quick post on few new features and resolved bugs:

1. Google maps copyright-bug:



Sometimes the GoogleMap's copyright information just "went out" of its predefined space. This is now solved. Thanks to Bernie who found this bug.

By the way, Bernie have a very nice panoramic site.

2. Added a "Remember me on this computer" checkbox:



...and now you don't have to login and re-login again every time you come on panoye.

3. Added the list of the most active users (i.e. users with most panoramas) on the main page.

4. Added the "Latest panoramas" list on the blog. If somebody want to try it you have to copy-paste this code:
<div id="latest_panoramas_widget"></div>
<script src="http://www.panoye.com/feed-json-new.10.json"></script>
<script src="http://www.panoye.com/js/latest_panoramas.js"></script>

...on your web page.

PS. I'm still waiting Amazon S3 to start working normally :(

PPS. Finally ;) It works now...

Problems with images

It seems there are problems with displaying images on panoye (not all -- the latest 20 panoramas are OK).

But... Well... The problem is with the Amazon S3 service. The only thing we have is - wait untill they solve it. I hope it will be soon!

Anyway, the rest of the site works fine.
