PTGui Pro puts images in wrong order

[Peter Smith]

I am loading 12 source images that are named DSC4900.tif through DSC4911.tif - this is the correct left-to-right order and they show up that way in the project assistant and on the source images tab. But, when I align them images and view the result in the pano editor, the order is all messed up - left to right it is 0, 1, 5, 9, 2, 6, 8, 10, 3, 11, 7, and 4. These are admittedly low contrast and low detail images, but still! How can I force PTGui to use the specified left-right order?

Thanks for the reply, but this does not work at all. Following the instructions in the FAQ, there are no images in my project that are linked to anything other than an adjacent image.

Why can't the program simply use the specified image order? Or, at least let the user specify which images should be linked by control points? Thanks for any additional input you can provide.

If you shoot multirow or spherical image order and alignment can be
totally different.

This is possible. Either set the control points manually or choose the
adjacent images in Control Points tab and press Ctrl+Shift+G (or choose
Gernerate Control Points for select images from Control Points menu).
You can advance to the next pair with the red arrow. Could be you need
to switch to advanced interface on Project Assistant tab first.

It may help if you initialize the positions of the images by visiting the Image Parameters tab (in Advanced mode):  select all the entries in the Yaw column and click on the Fill Yaw button.  Key in the nominal yaw increment used in the shoot and click OK.  Then go to the Project Settings tab and uncheck the "Roughly arrange images first" box in the "Align Images" behaviour section.  This will preserve the initial image positions when you run the Align Images option on the Project Assistant tab.

If neither this nor Erik's advice helps matters,  please upload copies of the images somewhere (half size jpegs should be good enough) and post a link here.  You can use the free service at www,ge.tt if necessary (no need to register).

Hi Peter,

The image ordering is irrelevant to PTGui, this is because it can do
multi row panoramas, or panoramas with zenith and nadir images. The
images can be in any order and normally PTGui should figure out in which
way they overlap automatically. Apparently this failed in your case.

Could you make your images available? Otherwise I can only guess what
went wrong.

Please do not add attachments to your posts; instead upload your files
at a file sharing site (for example http://ge.tt/ ) and include a link
in your message.

Kind regards,

Thank you - turning off Roughly Arrange Images and setting the same nominal yaw for all images did the trick. I still have a few adjacent image pairs where CPs could not be generated, so I'll work on doing these manually and see how the result is. Thanks again for your help.

Peter, Assign at least two control point pairs manually between the images without points.  Then run the optimizer via the Optimizer tab.  With the images now reasonably well aligned, you can try generating some more points using the alternative feature: "Generate control points here".  You drag out a selection rectangle in one of the images on the Control Points tab using shift+left click, and then right click in the rectangle and select the sub-menu option to generate points here.  This often works well, but only for images that are approximately aligned already.  It's useful for generating points in areas that are devoid of points.
