Stitching images of objects on roller table

[Michael Waldegger]

I am shooting downward at a long object that is being moved along a roller table. Each of the 9 images have 30% overlap with the adjacent image. I am not able to generate a suitable stitched image.

I have cropped the images in PT Gui to prevent unwanted control points from forming outside of the object of choice (i.e. the table supporting the rolling object is always in the image).

Can I specify the overlap? Some softwares such as MS I.C.E allo the user to specify the overlap.

Hi Michael,

Is the object flat? If not, then you cannot stitch those images due to
parallax.

If the object is flat and the camera is pointed perpendicular, you
should be able to get a good result by following 6.5:

If you can't get it to work, make your images available for download and
I'll be happy to take a look.

Kind regards,

I had some success thanks to your instructions. But I won't be able to do this for every single series of images. I am hoping to be able to take advantage of the batch stitching.

If I can upload the images I would love it if you could see what you can do.

The images are of a drill core box. There are 8 images. The camera is above, looking down. The core box is moved along a roller table under the camera.

Despite my initial success, I wasn't able to recreate it a second time.

Mike.
