Stitching Issue

by netline » Thu Feb 27, 2014 5:13 pm

Good Day All,

After reading a post from another user on how great APG 3.5.0 is I decided to upgrade from APG 2.

We finished taking photos of a Hotel a week ago, the Hotel needed 25 Panos and 16 of them stitched together perfectly without the need to touch the control points, the other 9 not so much. I tested the stitching in 3.5.0 as well as 2 and both really didnt like the stitch. Please note that the camera stayed in the same position the entire shoot so if 16 worked then you cannot blame parallax issues. What i also find strange is the fact that it gives an RMS of 2.7 but it is totally messed up.

I have inserted below a screen shot of the detection with out of the box settings (I also tested other different settings as well as xml import and NOTHING worked)

I have also placed the original files here https://www.dropbox.com/s/hzxcl815s29kng0/Conference%20Room%201.zip

Please would someone let me know if you get it right and if so how?

I look forward to some help with this!

P.S. I understand this is Beta software but you would atleast expect it to do what it is meant to do.

Hi!

Which camera do you use? Which lens? I read 16mm - but the you have much too much shots for a 16mm fisheye on fullframe or eve crop.
So i guess it´s NOT a fisheye?

Can you tell about your settings?

I am using a Canon 60D with a Sigma 10 - 20mm using to 10mm to shoot on Manual Focus

But why do the settings show 16mm? ok - it´s crop.

60D is x 1.6 so the 10mm would be 16mm

Do you have a solution to the bad stitch?

What kind of pano head did you use that allows mounting of the camera in landscape orientation?

You shooting pattern appears tro be 8-around at +/- 30 degrees pitch plus zenith at +90 bracketed x3.

Hmmm...just the sort of scene that the APP/APG CP detection system might have trouble with.

Lots of relatively featureless ceiling and a lot of repetitive patterns in the carpet.

Nevertheless it worked after i dragged the Zenith shot into position. One optimiztion stage and it worked fine.
Tried to move the shot in APG also - but that didn´t help much.

I was unable to get a stitch to include all images even after setting detection to High with APG 3.5 beta 2.

I don't know why APG 3.5 beta 2 should have this much trouble with this image set.

To be honest: i expected the opposite! Thought APG would do it better than PTGui in that case - jusr BECAUSEthe patterns.

Well using just the brightest exposure and detection set to High I got a good stitch, with no control point editing.

Although initially it was upside down.
...........

Why it doesn't do as well with hard linked stacks with reference image set to brightest exposure I don't know.

That's a questions for Kolor.

Thank you for all of your assistance

What kind of pano head did you use that allows mounting of the camera in landscape orientation?

You shooting pattern appears to be 8-around at +/- 30 degrees pitch plus zenith at +90 bracketed x3.

It is a Nodal Ninja and it isnt landscape it is portrait but for some reason the panos always download as landscape and the camera refuses to allow us to change that setting. The pattern is correct and I have a xml script i use in APG 2 with papywizard that accepts 99% of all of our panos, now with APG 3.5 none of my panos are working with the xml, now it mostly works out of the box.

Hmmm...just the sort of scene that the APP/APG CP detection system might have trouble with.

Lots of relatively featureless ceiling and a lot of repetitive patterns in the carpet.

I know that it has APG has issues with repetitve patterns but this is why we have xml, and now that doesnt even work.

I was unable to get a stitch to include all images even after setting detection to High with APG 3.5 beta 2.

I don't know why APG 3.5 beta 2 should have this much trouble with this image set.

To be honest: i expected the opposite! Thought APG would do it better than PTGui in that case - jusr BECAUSEthe patterns.

It is annoying that after spending money on the upgrade I still have to open APG 2 to get some things done that APG 3.5 refuses to do. It is a bit of a let down

Kolor please assist with the above, it does feel like a step back with regard to xml through papywizard not working as well as APG 3.5 not doing better than APG 2 in some instances.

I believe there are known issues with Papywizard Import wizard (XML) with 3.5 beta 2.

Of course I wasn't using your XML data file.

Did you try 3.0.8?

Why it doesn't do as well with hard linked stacks with reference image set to brightest exposure I don't know.

I strongly suggest to merge the bracketed shots in Photomatix or Oloneo or so prior to stitching! APG then only needs to detect CPs in ONE layer instead of 3 layers.

Yes I do use a NN but in APG 2 i found it useful to use the following xml code to import correctly.

Code: Select all

I strongly suggest to merge the bracketed shots in Photomatix or Oloneo or so prior to stitching! APG then only needs to detect CPs in ONE layer instead of 3 layers.

Thank you for the advice but APG is supposed to do this and this is what i paid for.

I believe there are known issues with Papywizard Import wizard (XML) with 3.5 beta 2.

Of course I wasn't using your XML data file.

Did you try 3.0.8?

Nope but i will give it a go. and let you know the results

Thank you for all of your assistance

What kind of pano head did you use that allows mounting of the camera in landscape orientation?

You shooting pattern appears to be 8-around at +/- 30 degrees pitch plus zenith at +90 bracketed x3.

It is a Nodal Ninja and it isnt landscape it is portrait but for some reason the panos always download as landscape and the camera refuses to allow us to change that setting. The pattern is correct and I have a xml script i use in APG 2 with papywizard that accepts 99% of all of our panos, now with APG 3.5 none of my panos are working with the xml, now it mostly works out of the box.

If your camera has an orientation sensor you could try turning it off.

I did try that and didnt have any effect. The landscape issue does not effect rendering though

I just tried APG 3.0 and it did a perfect job with the xml which gave an RMS of 2.3 for the conference room and rendered without a single mistake.

My thoughts are that Kolor needs to spend a bit of time fixing the xml bug.

Hello netline,
The problem you reported has been fixed in beta 3.
My try on your images with papywizard import of APG 3.5 beta 3 gives me a better stitch than with APG 3.0
Let me know if you still have troubles with APG 3.5.
Best regards,
Antoine
