Scene Flow Models for Autonomous Driving Dataset

💞 If you find OpenSceneFlow useful to your research, please cite our works 📖 and give a star 🌟 as encouragement. (੭ˊ꒳ˋ)੭✧

OpenSceneFlow is a codebase for point cloud scene flow estimation. Please check the usage on KTH-RPL/OpenSceneFlow.

The files we included and all test result reports can be found v2 leaderboard and v1 leaderboard.

[ModelName_best].ckpt: means the model evaluated in the public leaderboard page provided by authors or our retrained with the best parameters.
demo_data.zip: 613Mb, a mini-dataset for user to quickly run train/val code. Check usage in this section.
waymo_map.tar.gz: to successfully process waymo data with ground segmentation included to unified h5 file. Check usage in this README.

🎁 One repository, All methods!

You can try following methods in our code without any effort to make your own benchmark.

SSF (Ours 🚀): ICRA 2025
Flow4D: RA-L 2025
SeFlow (Ours 🚀): ECCV 2024
DeFlow (Ours 🚀): ICRA 2024
FastFlow3d: RA-L 2021
ZeroFlow: ICLR 2024, their pre-trained weight can covert into our format easily through the script.
NSFP: NeurIPS 2021, faster 3x than original version because of our CUDA speed up, same (slightly better) performance. Done coding, public after review.
FastNSF: ICCV 2023. Done coding, public after review.
... more on the way
