Trouble report 534

Images are placed side-by-side rather than properly overlapped

Versions affected

4.0

Description

This problem causes The Panorama Factory to occasionally produce stitched images where adjacent images overlap by just a tiny amount. The images appear to simply be placed side-by-side rather than properly overlapped. The problem applies to fully-automatic and semi-automatic stitching methods.

This problem occurs because the minimum and maximum overlap percentages on the Alignment properties dialog do not work properly for tilted and/or rotated images. The overlap percentage computation does not take into consideration that there are transparent pixels at the sides of the images. So the overlap percentage tends to be overestimated.

Workaround

You may use one or the other of these workarounds:

Workaround 1

Correct the image alignment using the manual alignment method. Refer to the help section Manually aligning images for step-by-step instructions.

Workaround 2

If you are using fully automatic stitching, change to semi-automatic stitching. Place 5 pairs of stitching points on at least one image pair. Then place one pair of stitching points on the remaining image pairs. A single pair of stitching points sets the image-to-image alignment without affecting the image warping.

Status

Corrected in V4.1.
