A PyTorch implementation of the SECOND 3D object detector for LiDAR point clouds, supporting KITTI and NuScenes datasets with sparse convolution-based networks. The project is deprecated in favor of OpenPCDet and mmdetection3d.

Use cases

• train a 3D object detection model on KITTI point clouds
• run SECOND detector on NuScenes dataset
• detect cars and pedestrians from LiDAR scans
• train PointPillars for autonomous driving perception
• benchmark 3D detection AP on KITTI validation set
• prototype voxel-based sparse convolution detectors

When to choose

• you need the original SECOND reference implementation for research comparison
• you must reproduce legacy KITTI/NuScenes results from 2019-era papers
• you are working with spconv 1.x codebases

When to avoid

• you are starting a new project - use OpenPCDet or mmdetection3d instead
• you need spconv 2.x support or active maintenance
• you need production-ready 3D detection with bug fixes
