GeoAuxNet: Towards Universal 3D Representation Learning for Multi-sensor Point Clouds

1 code implementation CVPR 2024 Shengjun Zhang, Xin Fei, Yueqi Duan

In this paper, we propose geometry-to-voxel auxiliary learning to enable voxel representations to access point-level geometric information, which supports better generalisation of the voxel-based backbone with additional interpretations of multi-sensor point clouds.
