About
SurroundOcc is an advanced AI tool developed for multi-camera 3D occupancy prediction, primarily targeting autonomous driving applications. It reconstructs comprehensive and consistent 3D scenes by extracting multi-scale features from camera images and lifting them to 3D volume space using spatial cross-attention. The tool then applies 3D convolutions for progressive upsampling and multi-level supervision. A key differentiator is its pipeline for generating dense occupancy ground truth from sparse LiDAR points, leveraging existing 3D detection and semantic segmentation labels without requiring extra human annotations. This process fuses multi-frame LiDAR points for dynamic objects and static scenes separately, followed by Poisson Reconstruction and voxelization to create dense volumetric occupancy. SurroundOcc supports both occupancy prediction and ground truth generation on custom data, offering flexibility for researchers and developers in the autonomous driving domain.
