## GPU Acceleration
ODM has support for doing SIFT feature extraction on a GPU, which is about 2x faster CPU on a consumer laptop. To use this feature, you need to use the `opendronemap/odm:gpu` docker image instead of `opendronemap/odm` and you need to pass the `--gpus all` flag to docker:

The implementation is OpenCL-based, so the acceleration should work with most graphics card (not just NVIDIA).

If you have an NVIDIA card, you can test that docker is recognizing the GPU by running:
