Mosaic Panorama Script

[pdesmidt]

Hi,

I'm building a film scanner using a dlsr. Bascially, I move a film carrier on a glass plate and take 1:1 pictures of the negative with a macro lens. For instance, it takes 25 pictures to cover a 6x7cm negative.



The results have been good, but there have been some problems with stitching, especially on negative with areas of very low detail.

For those negatives, the best thing so far is for me to manually adjust each tile in Photoshop in difference mode, but that is a bit tedious.

It'd be helpful to have a scrip that would place the tiles in rough position which could be refined manually. Is that something that could be done with a script?

Thank you for your help!

Would Photomerge set to »Reposition« and with »Blend Images Together« unchecked not achieve pretty much that?

Other than that one could naturally arrange 25 images in a predefined way via Script.
Could you post a set of sample-images (in lores maybe)?

Hi,

Thank you for the reply. I haven't had much luck with photomerge.

Here's the overall image:



You can down load a rar archive with all of the jpgs. at:
http://dl.dropbox.com/u/3595413/Light%2 ... %20try.rar

It is a 5x5 zig-zag mosaic, with 20-25% overlap.

Perhaps using the 'place' command?

For instance, the script could:
1) create a new canvas, something like 10820 px by 13100 px @ 300 dpi.
2) Get pointed to a folder where the files will be in order, i.e. the first file should go in spot 1, and so on.



3)Place the first file on the canvas and move it to position 1.
4) Flatten.
5) Place file 2 in position 2, and repeat, with each file on a new layer.

Having a script that could do this would really speed things up.

Well here is a script that will do that, you will need to have the "Reverse" checkbox ticked to get the files in that order.

Paul,

That's brilliant! The UI is very nice, and it's speedy!

Perhaps I'm doing something wrong, though, as the tiles don't quite end up in the right order:



Thank you very much for your help!

[Paul MR]

Ah, yes. Just reversing the file order won't do.
The script is designed to place the files left to right top down; or top down left to right.
To get it to work the files would need to be renamed.
Sorry about that.

Hi Paul,

No worries. Renaming is easy.

Thanks again!

Paul,

This is an extremely useful script, thanks for posting it. I have a similar problem, and I think that I can adapt this script to my purposes, but I wonder if you could offer a little bit of guidance.

Here's the problem: I have a number of images that need to be stitched together into a panorama, but the images don't fit together quite as nicely as the ones above, so I need to be able to program in offsets for each photograph in the panorama. I can't use Photoshop's panorama maker because I have 130 sets of images that need to be stitched together in exactly the same way. I can use the same offsets for each panoramic section, but I need to be able to define them in advance.

I have some programming experience with C++ (back way back), so this code isn't completely mysterious to me, but I'd like to know what you think the best way to go about making the change. It looks to me like the TLX, BRX, etc. variables are the coordinates (in its own layer) of the image to be moved, and the coordinates where it is to be placed in the background layer, and that I should probably start by fiddling with those. Is that about right?


Any ideas?

Thanks,

[Paul MR]

Yes,
TRY = Top Right Y
BLX = Bottom Left X
Etc..
Also the script creates the full size document early on..

Code: Select all

var w=app.activeDocument.width*Across;
var h=app.activeDocument.height*Down;
var offsetX = app.activeDocument.width.value;
var offsetY = app.activeDocument.height.value;
app.activeDocument.resizeCanvas(w, h, AnchorPosition.TOPLEFT);

So you would need to add the offsets to the document as well.
