Thanks Alexey, looking forward to that. If I can be of any help please let me know.

Bug Reports / Alignment crashes Metashape when viewing another project simultaneously
« on: August 23, 2020, 04:03:08 PM »
chunk.alignPhotos() step ran through Python crashes Metashape, whenever I open and view another dataset in in another Metashape instance on same PC. Not instantaneously, but just before it finishes alignment.
Metashape v.1.6.4 64bit, 2x RTX2080TI, no CPU when using GPU, latest game ready drivers, cleanly installed.
I also submitted several crash reports.

General / Re: Crash at dense cloud processing - CUDA ERROR

This seems to be referencing the same error and they've found and fixed the culprit as part of Python libs.
https://github.com/pytorch/pytorch/issues/20635
I still have this happening randomly on 8 different workstations with RTX2080Ti, GTX1080Ti and TitanX cards, all running version 1.4.5 and latest Stable Studio drivers (431.70).
It is not extremely common, but I have a crash every cca 1000 projects or so.

General / Ideal worker PC for large cluster
« on: October 25, 2018, 09:25:18 PM »
Hey,
I'd really like to hear your opinion of running a pretty large (50 to 150 workers) cluster of PhotoScan machines. What hardware would you pick for best cost-effectiveness and performance in this case?
I am collecting from 9 to 25 photos with 12 Mpx every second, depending on the job, with surveys running for several weeks at a time, and want to have at least a chance of processing it.
Thanks

General / Re: Multi-camera setup
« on: April 19, 2017, 12:07:58 PM »
Let me explain the setup a bit further to make potential answers to this question slightly easier.
We collect continuous imagery flow with 5 FPS with all three cameras, and the ROV is flying (mostly) in a straight line, so it is a kind of "aerial survey" scenario. Positioning is also well defined, with excellent, sub centimetre relative positioning and <0.5m absolute positions derived for each photo location, along with survey grade INS providing roll, pitch and yaw of the ROV.
I had good success with loading in the flight logs through GUI, but i would like to make the process a bit more robust for operators that are not so skilled, hence python. I would also like to separate the photos from the three cameras (which are of the same make, model and have fixed focus) into calibration groups for each camera. Is this achievable through GUI, i can find my way around Python interface myself afterwards.
Thanks

General / Multi-camera setup
« on: April 18, 2017, 11:25:12 AM »
Hi,
I'm using three synced cameras rigidly mounted on a ROV (remotely operated underwater vehicle) with about 70% overlap at typical survey altitude.
What would be the best way of importing them using a Python script, so they get calibrated as separate cameras, but contribute to the same 3D model?
Also, as the scene needs to be left undisturbed I cannot place scale-bars or measure the objects with divers, but I need consistent scaling of the object. Having a fixed baseline between cameras should help, or am I not getting the operation principle?
Thanks
