We extend Segment Anything to 3D perception by combining it with VoxelNeXt. Note that this project is still in progress. We are improving it and create more examples. Any issue or pull request is welcome!
Segment Anything and its following projects focus on 2D images. In this project, we extend the scope to 3D world by combining Segment Anything and VoxelNeXt. When we provide a prompt (e.g., a point / box), the result is not only 2D segmentation mask, but also 3D boxes.
The core idea is that VoxelNeXt is a fully sparse 3D detector. It predicts 3D object upon each sparse voxel. We project 3D sparse voxels onto 2D images. And then 3D boxes can be generated for voxels in the SAM mask.
- This project makes 3D object detection to be promptable.
- VoxelNeXt is based on sparse voxels that are easy to be related to the mask generated from segment anything.
- This project could facilitate 3D box labeling. 3D box can be obtained via a simple click on image. It might largely save human efforts, especially on autonuous driving scenes.
- Basic requirements
pip install -r requirements.txt

pip install git+https://github.com/facebookresearch/segment-anything.git
- spconv
pip install spconv
or cuda version spconvpip install spconv-cu111
based on your cuda version.
Please try it via seg_anything_and_3D.ipynb. We provide this example on nuScenes dataset. You can use other image-points pairs. The point to image translation infos on nuScenes val can be download here.
