GaussianOcc3D presents a multi-modal framework for 3D semantic occupancy prediction in autonomous driving, unifying camera semantics and LiDAR geometry within an adaptive 3D Gaussian representation. The framework achieves state-of-the-art mIoU scores of 28.9% on SurroundOcc and 49.4% on Occ3D, also showing superior robustness in rainy and night driving conditions.
Key insights
- Utilizing 3D Gaussian splatting as a continuous and adaptive scene representation effectively addresses the 'representation crisis' by focusing computation on object surfaces and avoiding the cubic complexity of voxels.
- Dynamic, consistency-aware fusion, achieved by adaptively reweighting camera and LiDAR contributions based on semantic consensus and reliability, significantly enhances robustness in adverse weather.
- Integrating Selective State Space Models (Mamba) within the Gauss-Mamba Head allows for efficient, linear-complexity modeling of long-range spatial dependencies among 3D Gaussians, improving global scene understanding.
