General / Manually introducing Camera Model
« on: April 30, 2018, 10:16:36 PM »

We have been flying with a UAV over a forest plot. After extracting the frames with Photoshop I always lose the camera info, so when I try to calibrate it, it appears as "unknown camera". Is there any way in Agisoft to manually introduce Camera model so that the software can make the proper lens correction, etc.?

Thanks a lot!

Input data for computations on GPUs are generated on CPU, so when you have very fast eGPU - your CPU can became the bottleneck (especially when computations are in low quality - because CPU work part to GPU work part ratio will be bad).

When slow GPU added (AMD 560) - it adds pressure in input data preparation part, i.e. CPU tries to feed both GPUs and so fast eGPU will be used less.

P.S. this is just typical reason for the described behavior, and if my speculation is correct - you will see speedup with AMD used in case of higher depth maps quality. (because of better CPU work part to GPU work part ratio)

Interesting! Thanks a lot! So... I'll turn it on everytime I use depth filter. If disabled, I'll let Nvidia take the whole part!

Nothing? Technical support? Anybody out there?  :-\

If the internal AMD's are active, there's about a 10% increase in processing times.

Does it also happen to you? That internal AMDs seem to slow the process instead of increasing computability leading to higher processing times?

Hi all,

I am trying to slice a 10min 4K Video into single frames. Apparently, that is what "inport video" function does. Problem is, when I do that, the system just crashes. It eats all the RAM, it starts paging it into SSD till it fills it all up, and then the whole system crashes. When I check it in Activity Monitor, Photoscan is using up to 80GBs of "RAM". I have tried different things like do it with a 2sec 30fps video which should give me max 60 images. But, when I restart the system and look into the destination folder, there are like 140 images (90% of them being exactly the same) which makes no sense at all.

Are you aware of this? Am I doing something wrong? Is there a minor fix for it? Is it just with my setup?

- AgiSoft Profesinoal 1.4.1 build 5925 (64 bit).
- Macbook Pro 15' (Late 2017) i7-7920HQ @3.1 GHz
- AMD Radeon Pro 560 4GB
- eGPU Box with GeForce GTX 1060 4GB VRAM

I tried using the different GPUs, it crashes anyway.

I would really appreciate some help.

Thank you very much!

Hi community,

Today I finally received a Sonnet eGFX Breakaway (eGPU enclosure). After some hours of scripts running up, uncountable reboots, crashes, etc. I managed to have it all working and wanted to share some amazing preliminary results I got.

My basic setup:

-   Macbook Pro 15’ (Late 2017)
-   CPU: Intel Core i7-7920HQ (4 Cores, 8 Threads @ 3.1 GHz, TB @ 4.1 (real 3.7))
-   GPU: AMD Radeon Pro 560 4GB
-   RAM: 16 GB 2133 MHz LPDDR3

-   Sonnet’s eGFX Breakaway Box 550 with Thunderbolt 3
-   ZOTAC GeForce GTX 1060 6GB

I used sample data from Parrot®. The sample contains 356 pictures at 4608x3456 resolution. I tried the following setups:

-   AMD + CPU
-   Nvidia + CPU
-   AMD + Nvidia + CPU
-   AMD + Nvidia

And just had time to Align and built de Dense Cloud in the lowest accuracy in boths. Here are some results.


The processing times between the discrete Radeon GPU and Nvidia are jaw dropping. A 253% faster! As you can see, the best setup would be the dual GPU + CPU but, the different between this and just running Nvidia+CPU or NVidia+AMD are insignificant.

As you can see, for those of you who don't want to give up on your laptop, here it's a powerfull alternative.

That being said, if you want I can try to find some time to do some other benchmarks with Agisoft Demo sets like the statue or any other in different accuracies. I will try to do it so that those considering in buying one have a little more information.

Thanks for reading and hope you found this useful!

Hi jmgc,

I will be doing exactly the same you are trying to do and I was curious how was your project doing. Could you achieve good results?

Hi Vikshut,

I don't know if you ever came across this file regarding Memory requirements for AgiSoft. If you have 30k pictures... well, I would say you should fraction your project (or you buy 150GB of RAM).
