New alignment parameter for background suppression
« on: February 28, 2018, 01:16:47 PM »
New alignment parameter was added in PhotoScan 1.4.1 release. It makes possible to suppress background from alignment procedure with few or even with a single mask. This can be helpful in turntable-like shooting scenario.
 
You can read tutorial and tool description and take a look at examples in blog post.
 
Please let us know if you have any problems using this tool.
With best regards,

Hello sastun1962,

What are the problems?

The workflow is simple:
- add all photos from the set,
- apply mask to the complete image IMG_6085.JPG,
- run Align Photos operation: High accuracy, Generic Preselection, key point limit - 40 000, tie point limit - 10 000, apply masks to - Tie Points, adaptive camera model fitting - enabled.
As a result you'll get the similar sparse cloud like on the screenshots on the article page.

Hi Alexey,
- if I try to use your banana project the cameras are always in the unique position and dont are "around" the banana
- if I try with a new proyect the alignement is impossible....

what I do wrong?

Hello sastun1962,

After processing you can copy the information from the Console pane (to enable the pane use corresponding option in View menu).

This looks like a great feature! But I do have some questions about the actual steps one has to take. Do you make the masks in photoshop? Do you run them on the entire set of photo's or just on a few? I assume you have to import the masks in Photoscan?

You can read about masking here.

Also note that magic wand can be used in incremental style with multiple clicking while holding Ctrl.

Hi,

In Photoscan 1.4.1 Pro, I have no access to this feature as shown on the screenshot.
How do I proceed ?

Thanks.

Nightingale,

Have you got at least one mask loaded? I'm not in front of my PhotoScan machine at present to try it, but I wouldn't be surprised if 'Apply masks to' was fixed at 'None' if there weren't any masks imported and hence no masks to apply.

Hi thanks for reply.

I have 271 photos.
I made and loaded the 271 masks.
And now I can change the field "Apply masks to".

Thanks again !
