New user - stitching problem

by olivierhess » Thu Jun 14, 2018 2:13 pm

Hello everyone,
I've just recently started experimenting with 360 sphere photography and I'm using Autopano Giga 4.4 (trial version) to familiarise with the stitching process. I have experienced some stitching issues when I tried to put together this sphere.

In particular some lines were not matching perfectly in places where you'd expect to have an easy stitch (I think) and I was not able to use the nadir image to cover the tripod at the bottom. It was just not picked up by the software, but maybe I did something wrong here.
I have also noticed that the software tries to find matching points using the watermarks. Is this normal?

I have attached a few screenshots as well as a rendered sphere for you to see. Could you please guide me and tell me if I'm doing something wrong?

Computer specs: iMac (Retina 5K, 27-inch, Late 2014), 4 GHz Intel Core i7, 32 GB 1600 MHz DDR3, AMD Radeon R9 M290X 2048 MB.

Camera and lens: Canon 5D MK4 + Canon 17-40mm set at 17mm (Is 17mm a good focal lenght for what I am trying to do?).

I used a Manfrotto 300SPH mechanical head and I shot 18 photos at 0 degrees, 18 photos at ±60 degrees and one nadir.

Here's the stitched sphere: https://www.dropbox.com/s/4brbssjeu6x4j ... 0.jpg?dl=0

Hello and welcome!

Did you apply any blending? If you click the preview icon in the bottom left corner of the preview windows (green icon left to the zoom menu) it applies a standard colour correction and blending so it will remove ghost issues. If not, can you check in the layer window (bottom part of the panorama editor) if you have one single layer?
Also, feel free to share your original footages so that we can have a look.

Let me know if it helps.

Best,
Olivier

P.S. Autopano adds watermarks when you render the pano
Cheers,
Olivier

Hi Olivier :)

To be honest I'm not sure about that as I am still learning/playing with the software.
I started a new pano project from scratch and this is what I see after I let the software detect the images, I haven't done anything else.

In this case I can see A LOT of ghosting, probably due the nodal point? As I'm using a manual head I might not have set it perfectly.

As a next step I clicked on the Preview icon as you mentioned and the ghosting/not matching lines seem to have disappeared but not completely as they show up in some portions. (Photos 3-4-5)

What would be the next step I should take?

Unfortunately I am not able to share the captures :(

Something else that I have noticed is that my Mac takes very long to process the Preview or to do other adjustments in Autopano. Is it normal? I am a bit worried because I am just working with small res JPEGs but in the future I will have to work with TIFFs and I wouldn't want to wait for ever just to see a small setting change :D Considering my Mac specs, is this a normal behaviour?

Hope to hear from you soon.

Hello,

This type of errors can have various causes. You haven't set the nodal point correctly so you have a lot of parallax, or overlap between pictures is too high for instance.
Can you share or send your original pictures?

Kind regards,
Olivier

Hi Olivier,

I'm sorry but I'm not able to share the original pictures :(

I'm pretty sure it's the nodal point as you say. I was using a manual head which I probably haven't set up perfectly.

Hello,

If it is a confidential problem, I can send you a PM so you could send the pictures (via Wetransfer for instance). All the emails we received are always and automatically treated as confidential.

Let me know.

Cheers,
Olivier
