General / Filtering depth map stage?

« on: January 20, 2015, 04:31:06 AM »

HIya

Is the Filtering depth map stage (second part of dense cloud creation)   GPU or CPU based

I know the step before it is GPU, but then Im runing "Filtering Depth Maps" and the CPUs are maxxed.  So is it mainly CPU?

Do you get much noise on the high ISO??


I have a sony rx100M3 and liking it so far (except its lack of gps)

Use shutter at 1/1600-1/2000  and iso 100.
Aperture depending on the day. I try to shoot in overcast so need F4 or so

Focus manual to infinity.
Flying the 3dr Iris+

Settings are good for the matching ground shots too, combination of hand held and 2m-4m pole.

But still practicing!!

General / Re: Crash - how much Ram is recommended? I have 20 gigs

« on: January 20, 2015, 03:17:36 AM »

HIya

The more ram the better 9obviously) as it avoids any paging etc

My machine at work has 192G and Ive even maxxed that one (but not often)

My home machine has 32G and I can usually keep it running at 24G used then swap if needed)

Photoscan seems to reasonably good at keeping the RAM at a level where you machine is still functional. But at the cost of swapping and slowing down the processing.

Speaking of swap, if you are swapping get a SolidState drive for the scatch disk. It'll help a little at least.

Question to the Agisoft team.
Is there any way on the CPU/RAM intensive processes that you can use GPU ram as first swap? I have 2x 4G 9xx series card, so potentially an extra 8G there not getting used while the CPU processes are running?

Cheers

General / Re: Best camera for Photoscan?

« on: January 20, 2015, 03:11:39 AM »

well the title said Best Camera for Pscan... not Best cheapest Camera for Pscan... this is why I posted..

btw, are you sure of your statements ..? have you done any tests yet..? what about a Hasselblad H4D ?

best
f/

Hoping for some time to test our H5D and what subjects it will be best suited to.

But in more genral terms I tend to think along the lines of image pixels per degree of fov, desired working distance and the final resolution required. This gives you a better idea of what type of camera/lens combination you need, and once you have that you get the best your budget will stretch to.

Reshot a test project last week with a Canon 5D2 but brought the wrong lens. (50mm instead of 24mm) went ahead anyway and while the dense cloud is freaking awesome, I'll have to scale the images back from 21MP to 12MP so that I can create a mesh. Could have got a similar result with a Canon S120.

You can leave the images scaled up hi, and jsut use a different dense cloud seeting. I believe each lower setting sub samples the photos.
Ultra all pixels sampled
High evernn 2nd pixel sampled
Medium every 4 pixels

ETC (at least that is what Ive read and under stood)

The good thing about keeping high images is at texture time, you can get a much sharper texture projection.

Ah

Of course it gets the same bug:

You can see if keeps reworking on the same image

I'LL PM  a link to the psz so you can try like you mention

Hello pjenness,

You've used Python command to align cameras?

Hiya

Yup

Nevermind, looks like after a few hours in it dropped from 146 hours to 9 remaining, I'll let it run its course.

Bug Reports / Re: Photoscan 1.1.0 build 1995 - Align photos

« on: January 18, 2015, 12:04:39 AM »

Hello pjenness,

I can suggest to export markers to .xml file and them remove them from project, then align photos and save the project. Then you can import the markers back, reset camer alignment and do Align Selected Cameras operation via GUI or using Python from the Console pane:

Code: [Select]

PhotoScan.app.document.chunk.alignCameras()
If it doesn't work, you can send the proejct to us and we'll calculate the camera alignment in our internal version and send the project back to you.
The update with the fix will be release in a week or two.

Trying this now.
I matched photos
Remover markers
Aligned photos (took under 8 hours)
Reimport markers
Align photos .......

The final align photos is saying 146 hours now (with markers) .....does that sound right??? Hopefully that goes down since the orgininal(but incorect) align took under 8

Cheers

HI thanks!!

I'll give it a go

I cant send the project..its 1600 photos, will kill my internet quota

Feature Requests / Smart masking options

« on: January 17, 2015, 03:32:38 AM »

Hiya

Ive found recently when I have flat white sky in manay of my images somtimes it gets calculate in the wrong place and I get white on top of th emodel. Usually when I dont have enough down angles to define the top correctly

This happens a lot with cliffs etc wher my main angles are from low looking up

Im finding the best solution is to mask out the sky.

It would be great if there was a smart solution for this (other than magic wanding manually every photo)

Cheers

Feature Requests / Re: Shortcut for adding and subtracting mask

« on: January 17, 2015, 03:29:57 AM »

ctrl-shit-A
ctrl-shift-S

Ive done a set of 1600 photos and one of 800 recently. Magic wanding out the sky and masking.


Took hours!! but those hotkeys were good.

Also just right clik opens the menu and add is the first one there , so got into routiune of double click phot, click sky right click add (or ctr;-shift-s) double click next photo......

Thank you Mac,

We'll try to fix it for the next update.

Hi Alexey,

Any idea of the next update or preRelease, as I am stuck on this also.  (I cam from the features request thread about saving)


Happy to test the bug fix for this feature.

I have a larger data set of 1600 photos. They almost all aligned but got patches of overlapping, so am using some manual points to help, but get the infinite processing bug. (1400%+ then I cancelled it after 2 days)



Let me know if you want it stress tested   

Cheers

Feature Requests / Re: More save options

« on: January 17, 2015, 12:34:39 AM »

Hello pjenness,

Are you using latest 1.1.0 build?

This problem seems to be similar to the following one: http://www.agisoft.com/forum/index.php?topic=3198.0 and might be related to the preliminary placed marker projections. This issue will be fixed in the next PhotoScan update.

Yup looks like same issue.
Using markers.   Im using the 2004 version which I think is latest?


Cheers

Feature Requests / Re: More save options

« on: January 16, 2015, 12:18:55 PM »

Thats a good start..is there more information somewhere about the exact code need to use?


I have an aling process that went all night, got to 100%, but hasnt stopped...its now at 665% and still going.
The CPUS are maxxed, and have been for 14hours.

Im not sure if its stuffed, or jsut leave it to let it finish.

Feature Requests / More save options

« on: January 14, 2015, 10:51:12 PM »

Hiya

Its probably been bought up before, but the ability to save at each step of th process would be appreciated.

For example, the ALign photos has a number of sub steps

Detecting Points
Matching points
.
.
etc

Working on a big data set (1600 photos), I'd love to be able to save at each step. And reboot , flush memory etc.
I had an align last night get through a few of the steps then crash, it would be great to be able to restart from the last completed step.

Thanks!
