General / Re: What is the method if I have a second set of photos of underside of object ?

« Last post by Steve003 on Today at 01:16:29 AM »

Hi,
Its taken me ages to mask up two photos of those in chunk 1. No way could I ever mask up my 2000 this  way.

I have imported the two masks for chunk 1 using the correct {name}.bmp approach, I see the two masks in mask view, I then run align photos selecting the settings as per the blog on this, i.e accuracy high generic preselection tick key point 40,000  tie point limit 10,000 apply masks to tie points adaptive camera tick and hit ok.

How do I know this has worked, I still have just 2 of 15 photos showing a mask in mask view.

Hi Alexey,
attached a screen grab of my 1.4.5 magic wand area, unlike the video (also attached) it has no options there.

I would at the moment prefer photoshop but not sure how I bring the mask in and use it for 'apply masks to tie points'.

my object got placed in a different position 7 times so I presume I need 7 masks one per chunk, and use the tie points method 7 times ?

Hi Alexey,
I shall send via wetransfer a video showing how despite many crtl clicks, the scissors get distracted from the edge on a gridded board. I wish that video was in English !

I need instead to create a mask using photoshop and then use that in 'apply masks to tie points' though I dont know how to bring the mask in for the tie point command to use it.

How is that done ?

Mak11, I am simply separating out problems I need help on, if they were all stuffed into one thread the initial post would be too lengthy people dont read what looks long, also the title would simply be help needed with this lot, and would not feature keywords to be useful for anyone searching on a similar problem they are having and they wouldnt want to try and find an answer in a thread full of various answers and problems. Also to keep adding new problems into the initial thread would not see folk realise it had new content so it would be overlooked. I wish all was well and everything worked but instead it isnt and I need to find out whats wrong, what to do etc and it is best such are separated out, as is normal practice on forums. I normally get told keep the problems as separate posts to help others navigate and search on such !

I have encountered problems I cant find answers to on youtube or in existing forum threads, only then do I post, and need to get operational now, rather than post one a week as if rationed and take 2 months to get operational.

Hi David,
Is there not going to be a catch22 situation, unable to use the model to chop away accurately at the baseboard where the model touches it, due to a snowdrift effect going on, because the photos needed masking prior to use to deter Agisoft from creating a poor definition at that object/baseboard junction ?

in other words or maybe saying it just as badly, to get a model  with well defined object/baseboard junction so as to edit mesh away and create the masks, one needs well masked photos and to use agisoft to mask all the photos in one fell swoop with this method we need the model already created from well masked photos.


I have several chunks, each one where the object was repositioned on the gridded table beyond which is a concrete floor and buildings, flor and buildings which appear occasionally in some of the shots, gridded table in all.

I am wondering how I remove all those backgrounds as fast as possible.

If I generate model first, surely the existence of the backgrounds will cause inaccuracies, poor edges where it touches grid etc, but to do as your method and delete background away from model  which I also saw on youtube and liked the idea of, I have to create an accurate model, so catch22.

Hello Steve,

I think the following video is quite similar to the one you have posted in another thread but also gives and idea of Intelligent Scissor masking:
https://youtu.be/-SyYKWFShRA?t=147

Left-click on the first point, hold CTRL, move the cursor along the edge of the object, left-click again quite regularly to avoid "straight lines" drawing.

Maybe you should keep all your question under one thread instead of creating one every time you wish to complain about something? Spamming the forum like that isn't the best way to get answers.

General / Re: photo masking tools none work where is tolerance options ?

« Last post by Alexey Pasumansky on June 24, 2019, 09:40:42 PM »

Hello Steve,

Magic wand tolerance options are available in the version 1.4.5 and even in 1.2.6.

Scissors instrument may get confused, if there are considerable contrast changes in scene by the borders of the objects or elements in the background.

You can import the masks from the external source (separate set of black&white images or from the alpha channel i.e. transparency channel), if you prefer external applications for mask drawing and find them more convenient for your needs.

Hi,

I am having terrible experience trying to mask an image, intelligent scissors get sidetracked by lines on my grid table. it hugged the object then when it came to a grid box line it lost the edge trace and went round my inch box on the grid, then eventually I ended up with one straight red dashed line after having gone a few inches.
tried paintbrush but got lots of peculiar bits.
tried magic wand but not any better.
https://www.youtube.com/watch?v=A-N8zD6svvY  he has standard prog and uses tolerance values in magic wand options but I have Photoscan 1.4.5 and those options are missing.

I wish to follow the apply masks to tie points method, can I use photoshop instead to mask the image or two required and how do I bring this in and use it in the tie points process ? I could have masked 20 in the time it took to not even manage to mask using the agisoft tools.

Whenever you are working on the software and eventually crash on you and you need to open it again....

How do you solve this ?  Just curious .

To me it sounds like there is a file saved as a lock file ?
