Best fit for GPU is feature extraction and matching. For this, calling opencv's implementation is what would make more sense. There is no python API for that yet AFAIK.
BA is probably too ambitious

Last week I received a couple of GPUs, I'll try to make a Python wrapper to use it in csfm.c
By now, in cudafeatures2d are only available ORB and BruteForce matching.

I wanted to see if their was any updates on adding gpu support to this? See other discussion over at Open Drone Map to figure out if processing can be accelerated with GPU/s . OpenDroneMap/ODM#92 (comment)

Any sort of update on this?

Hello, Is there any GPU feature yet ?
from opensfm.
A tentative GPU branch is pending for merge here : #623
Wasn't yet merged, as the speed-up wasn't dramatic compared to multithreaded CPU. More detailed comparison on > 20K features might prove it is maybe faster, but for now, multi-threaded CPU still wins.
