General / Re: v1.3 Performance Regression

Thanks Alexey,

So I have to wait for a new 1.3 release or the optimization is ready in the Version 1.3.0 build 3772?

Alexey,

Thank you, but the main problem is the merging is very slow, compared with a project with 2,000 images which was just a matter of 10 minutes, this took us around a week and eventually ate up all memory and could't finish.

Any update with the merging problem ? My team is still pending and making no progress.

FYI, we just got a 1070, some benchmarks for dense cloud generation, high quality, building sample

1.2.6

2017-03-01 04:44:06 finished depth reconstruction in 691.51 seconds
2017-03-01 04:44:06 Device 1 performance: 1174.18 million samples/sec (GeForce GTX 1070)
2017-03-01 04:44:06 Total performance: 1174.18 million samples/sec

1.3.0

2017-03-01 05:00:56 finished depth reconstruction in 208.065 seconds
2017-03-01 05:00:56 Device 1: 100% work done with performance: 487.714 million samples/sec (GeForce GTX 1070), device used for 343.541 seconds

General / Large sample dataset
« on: March 01, 2017, 01:40:02 PM »
As we will have large production projects in the future and we just built a powerful server it, we want to find some large dataset to do stress test with our stacks. But it seems it is quite hard to find on Internet, all I found so far are:

https://www.sensefly.com/drones/example-datasets.html
https://dronemapper.com/sample_data

I want to test some dataset as large as 10,000+ images, with geotagging and ideally with GCPs.

Is it possible to have larger dataset for test and training, or we can have other ways to build large datasets, e.g. combine all small datasets around the world into one/ dulplicating files/ buy datasets from providers?

Alexey,

The project was saved in psx format with depth map.

Please help!!

Now it will run for unbelievable time

24MP, multi-spectral image pairs

Other facts: http://imgur.com/a/jItfz ( those 3 expanded chunks)

While at the meantime, the estimated merging time keep growing http://imgur.com/a/n1BMi

 :'( :'(

Does it matter that we enabled "save depth map" before we start chunk merging?

We had quite a quick result with v1.2.6 and around 1000 images dataset before.

Thanks

General / Best practices for handling 30,000 + images
« on: February 24, 2017, 11:44:29 AM »
Hi all,
We are going start a aerial survey project which will have around 30,000 images collected. We will use Agisoft to process them and it is first time for us to handle such large amount of data.

So I want to ask for recommendation of both hardware and software sides:
- Recommended hardware configuration, ram, disk, GPU, CPU
- Cluster is necessary? If yes, how many nodes? The totally process time is reduced linearly to the number of nodes?
- Multiple chunks? How to balance number of chunks and the number of images per chunk.
- The best way to merge chunks? By markers? If yes, then we have to place GCP markers around the borders of flights?


Thank you in advance.

Thank you Alexey,

As to my other questions (incredibly long chunk merging time and rolling back to 1.2), could you give me some suggestions?

And "merge chunks"(6k images in total, 3 chunks, merge dense cloud and mesh) in 1.3 is incredibly slow

General / v1.3 Performance Regression
« on: February 24, 2017, 07:01:47 AM »
Win 10 x64
Agisoft v1.3
Dual Xeon
R390x


We updated Agisoft from 1.2.6 to 1.3.0 and we observed performance regression on all our workstaions, e.g. for "build dense cloud",

1.2.6:
GPU: 269mil samples/sec CPU: 106 mil samples/sec
1.3.0:
GPU: 45mil samples/sec CPU: 15 mil samples/sec
 

Now we want to rollback to 1.2.6 but our projects are already saved in 1.3.0. Can we safely re-install 1.2.6 and open our projects?

Bug Reports / Re: [Build dense cloud] Error: bad allocation
« on: February 21, 2017, 07:07:04 PM »
Thank you Alexey,

So network mode (even with only local node) is a recommended way to reduce memory consumption.

I have one more question about network mode, if I add one networked machine for acceleration, for example, one with 3 powerful graphic cards, then do I still need to install large amount of ram on it? Or less ram (e.g. 64GB) is enough ?
