General / Major Speed and memory managment overhaul needed
« on: July 21, 2018, 12:32:23 PM »
I've just recently decided to upgrade my gear and went from a 14.3Mp camera to a 24.2MP cam and suffice to say that Photoscan sure didn't "love" it at all. Neither did my PC or my electricity bill. The processing times are now unbearable (yes even the alignment process which can take 40 Minutes for 190 photos TIFF/16Bit in PS 1.4.2 while the exact same set takes 2 Minutes in RC which doesn't even use the GPU for this stage!).
Reconstruction is now faster compared to last year when using the experimental method but I now can't do it in ultra-high quality because I run out of memory given the resolution of the cameras so I will have to use the old method..which can take days now (build ultra-high dense cloud then high-poly mesh...). Photoscan seriously need to support out-of-core computation after all these years.

I just couldn't bring myself to use Reality Capture before because of it's horrible UI, serious lack of features compared to PS, horrible pricing and the fact that it's CUDA only. But I'm on the verge of grabbing an NVIDIA GPU & 3/month license just to process some of my scans given how slow PS has become for me.

I really hope that the Agisoft team is working on improving Photoscan's memory management in particular because everybody doesn't have 64GB in there PC (32GB here which have become nearly useless with 150+ 24MP cameras..).

Sorry for the small rant folks but PS is such an awesome piece of software especially in terms of features. A boost in perf for high res photo sets is really the only thing missing.

Cheers

ps. Using chunks can be a band-aid solution but definitely not the easiest or logical especially for single object scan projects when you simply aim to create a super high-poly mesh to use for baking

General / PhotoScan Roadmap
« on: June 07, 2018, 03:23:39 PM »
Hi there Agisoft Team,

I was wondering if you guys would ever release communicate what the roadmap of PhotoScan is?
Things la new features currently being worked on, performance improvements, target dates for release of new builds etc..

Regards

Hi everybody,

As stated in the title..When is OpenCL exactly being used during the Dense Point Cloud generation?
As far as I can see it is used at the "beginning" and then the whole "filtering depth maps" is all done on the CPU. Is that right?
Also, are you guys planning on using OpenCL for more computational tasks in the near futur?

Cheers
