HELP: time of estimation very long...

[tuffi]

Hi all,

please, i attach a images where you can see time needed for estimate camera position.

I think there is same problem...some time i saw strange number but after some hour it became right...now remain strange.

Do you think this is the real time needed or not?

The dataset is about 10k images and align at medium quality...

Thank you

Hello tuffi,

Which preselection option and point limits have you used for this project? Also please specify the type of the project - aerial or close range?

[tuffi]

Thank you, i use reference in exif data. Key point 40000 and tie 4000.

The project is an aerial survey at gsd of about 3cm

Hello Emanuele,

Usually after several first processing percent have passed the estimated time returns to the valid numbers, but here I see that after several hours the progress is still on 0%.

If the memory is sufficient (not all RAM is used) and you see CPU activity, then it seems to be in progress.

Hello, well done.
After 28h i need other 19h to complete the alignment.

I use 70% of CPU, 15% of CPU and 24GB of 128GB of RAM (At start of step PS used 65GB)....so I think that there is no other way to improve speed (I suppose beacouse I see that the CPU are not at 100%)? I'm right?

Maybe by a SSD drive?

Hello Emanuele,

What is the CPU model that you are using?

SSD wouldn't help.

Hi,

I've a system with two Xeon E5-2680 v4.

Hello Emanuele,

Do you see the utilization of both CPUs in the task manager? Or one CPU is idling? In the second case you need to make sure that bios is properly configured to use both CPUs.

Thank you Alexey,

The CPU1 is used at 100% every time. The CPU2 aren't used so much.

Now i work in remote. The first day i come back in office i check the BIOS..

Thank you...

Hello Emanuele,

There should be something like Node Interleaving or NUMA Group Size Optimization option. Also please execute the following commands from PhotoScan Console pane:

Code: [Select]

    import os
    os.environ
And specify the value of the following parameter: 'NUMBER_OF_PROCESSORS'  (don't copy the full output here, as it may contain sensible data).

It looks somewhat similar to the following thread:

Hi,

I tried the console command that you suggested, but i can't see the information relative to number of processor.

Anyway during a dense cloud generation i saw that windows indicate the use of two processor at 100%...

So I think...all ok.

The first time I can reboot the system I will check also in the BIOS.

Thank you...
