PanoTools NG: Can I fix line errors in PTGui? Moafaq moafaq.jamal@... 2014-Nov-05 03:16:28

Example of line errors:

I luckily fixed the line when I masked the angled images:

Is there an easy way I could fix parallax line errors in PTGui Pro before
blending? In the following photo:

the stairs appears in 4 images (2 at 0 degree and 2 at -45 degree). I tried
to add control points on each line of the stairs between the 4 images but
there were already enough control points and so it was automatically
assigned. I also tried to mask out the stairs in the two shot at -45 but
encountered other small line problems on the chair and floor (see below
picture) but it was better result. I had to align the images every time I
use mask.

I?m using D7000 with 16-85mm at 16mm on 303SPH head & 190XPROB tripod. I use
tripod legs to level the head so levelling is not 100% right but I think
levelling doesn?t affect parallax point! am I right?
I take around 32-38 images for one panorama:

In the Show Seams mode, the line of the stair looks just fine unlike the
blending mode:

The way I use to find the nodal point on the 303SPH is to point the camera
downward @-90 degree and turn on the viewfinder grid. move both the base
plate and the camera plate to the centre of the head. Then, point the camera
at 0 degree and move the 3rd base plate back and forth. I guess my head
setting is right so why I'm always getting line errors!? shall I just use
fisheye lens to make life easier!

The following tutorial (http://www.rosaurophotography.com/html/PS4.html) is
good if the line has short length.

Thank you
