Fluffiness on the edges
« on: April 18, 2013, 11:43:31 AM »
Hi,

I've recently started experimenting with photoscan and it continues to amaze me how well this works!

But I have a question! I often encounter these kinds of fluffy edges:

And here a single shot from the 32 photo's I've made:

And here is the photoscan file.

What most often causes these errors? I am using the 0.9.1 1654 Beta

I've tried using the gradual selection on te pointcloud to remove some suspect points but it does not seems to make a difference. Also After model creation these fluffies cannot be removed by using gradual selection.

Thanks for any pointers you might have

try use arbitrary mode and smooth settings. object is sharp that a very good. try use masks

 But the art of object is not easy to do, you will need a lot of images.....

Alright, So more photo's could be a solution, going to try that. Tried the smooth mode but that did not make any difference. Thanks!

Hello tristan_bethe,

More photos will help if they capture the inner parts of the chair back. Also you can mask the background parts that are visible through the back of the chair.
Best regards,

Ah yes, masking of course. This was a quick test and was much impressed with the results it gave apart from the artifacts. But if I understand it correctly it is the open faces on the back that have the tendency  to go funky a bit. Makes sense. Thanks Alexey!

Also I found that setting depth filtering to mild helped in this instance... Guess that is because so much is going on in this example.
