Not enough memory

[mskancke]

Hi.

Im hoping you can point out what I need to upgrade on my computer.

I have started the build dense cloud process on a job which contains 356 pictures/cameras of 4928x3264 uncompressed TIF's. All pictures is shot by our drone.
Dense cloud settings are High quality, and agressive depth filtering.

I've tried twich and both times the job has failed due to not enough memory, but at different intervals.

In console it says:
[GPU] estimating 652x1883x128 disparity using 652x942x32f tiles, offset 0

Some key specs about my computer

Intel I7 4770K
16GB 1600Mhz DDR3 RAM
2GB Geforce GTX770
Windows 7 Pro


My questions are:
Is there any settings in Photoscan that can remove this problem?
I have done a similar job with success, although with fewer pictures (around 200), but according to the table found on your Tips and tricks section 16GB should be more than enough when using Hight field.

Is it the RAM that needs upgrading or the GPU?
Should I go for a GTX770 SLI config or just make my boss buy TITAN (or maybe SLI Titan)

You would probably need at least 64GB of RAM for this kind of processing.

This table suggests otherwise:


Photos                     100   200             500   1000   2000   5000   10000
Lowest quality            25 MB   50 MB   125 MB   250 MB   500 MB   1.25 GB   2.5 GB
Low quality           100 MB   200 MB   500 MB   1 GB            2 GB   5 GB           10 GB
Medium quality            400 MB   800 MB   2 GB           4 GB           8 GB            20 GB   40 GB
High quality             1.6 GB   3.2 GB   8 GB           16 GB   32 GB   80 GB   160 GB
Ultra high quality   6.4 GB   12.8 GB   32 GB   64 GB   128 GB   320 GB   640 GB

Hello Marius,

Have you checked Task Manager for memory usage during processing? Has it reached the limit?

Please also check that 64-bit version of PhotoScan is installed.

Hi Alexey.

I have checked memory status while the job was ongoing. And its not even close.
I can also verify that I'm using Photoscan 64bit

Bump!

Upload the dataset, can help to process it if want.... and see where is the problem eventually...

[mskancke]

Thanks, where too upload it?

Its pretty big though, 41GB

[Wishgranter]

Hi, im recommend use Google drive (gmail mail account), buy 100 GB disk space for 3 USD per month, and upload in 1-2GB RAR archvies with RECOVERY RECORD for safety. its fastest way. Or any other way, that is fast enought......
