This representation mimics the well-studied image-based 2D bounding-box detection but comes with additional challenges. Objects in a 3D world do not follow any particular orientation, and box-based detectors have difficulties enumerating all orientations or fitting an axis-aligned bounding box to rotated objects. In this paper, we instead propose to represent, detect, and track 3D objects as points. Our framework, CenterPoint, first detects centers of objects using a keypoint detector and regresses to other attributes, including 3D size, 3D orientation, and velocity. In a second stage, it refines these estimates using additional point features on the object. In CenterPoint, 3D object tracking simplifies to greedy closest-point matching. The resulting detection and tracking algorithm is simple, efficient, and effective. CenterPoint achieved state-of-the-art performance on the nuScenes benchmark for both 3D detection and tracking, with 65.5 NDS and 63.8 AMOTA for a single model. On the Waymo Open Dataset, CenterPoint outperforms all previous single model method by a large margin and ranks first among all Lidar-only submissions. # Highlights - **Simple:** Two sentences method summary: We use standard 3D point cloud encoder with a few convolutional layers in the head to produce a bird-eye-view heatmap and other dense regression outputs including the offset to centers in the previous frame. Detection is a simple local peak extraction with refinement, and tracking is a closest-distance matching. - **Fast and Accurate**: Our best single model achieves *71.9* mAPH on Waymo and *65.5* NDS on nuScenes while running at 11FPS+. - **Extensible**: Simple replacement for anchor-based detector in your novel algorithms. ## Main results #### 3D detection on Waymo test set | | #Frame | Veh_L2 | Ped_L2 | Cyc_L2 | MAPH | FPS | |---------|---------|--------|--------|---------|--------|-------| |VoxelNet | 1 | 71.9 | 67.0 | 68.2 | 69.0 | 13 | |VoxelNet | 2 | 73.0 | 71.5 | 71.3 | 71.9 | 11 | #### 3D detection on Waymo domain adaptation test set | | #Frame | Veh_L2 | Ped_L2 | Cyc_L2 | MAPH | FPS | |---------|---------|--------|--------|---------|--------|-------| |VoxelNet | 2 | 56.1 | 47.8 | 65.2 | 56.3 | 11 | #### 3D detection on nuScenes test set | | MAP ↑ | NDS ↑ | PKL ↓ | FPS ↑| |---------|---------|--------|--------|------| |VoxelNet | 58.0 | 65.5 | 0.69 | 11 | #### 3D tracking on Waymo test set | | #Frame | Veh_L2 | Ped_L2 | Cyc_L2 | MOTA | FPS | |---------|---------|--------|--------|---------|--------|-------| | VoxelNet| 2 | 59.4 | 56.6 | 60.0 | 58.7 | 11 | #### 3D Tracking on nuScenes test set | | AMOTA ↑ | AMOTP ↓ | |----------|---------|---------| | VoxelNet (flip test) | 63.8 | 0.555 | All results are tested on a Titan RTX GPU with batch size 1. ## Third-party resources - [ONCE_Benchmark](https://github.com/PointsCoder/ONCE_Benchmark): Implementation of CenterPoint on the ONCE dataset - [CenterPoint-KITTI](https://github.com/tianweiy/CenterPoint-KITTI): Reimplementation of CenterPoint on the KITTI dataset - [OpenPCDet](https://github.com/open-mmlab/OpenPCDet): Implementation of CenterPoint in OpenPCDet framework (with configs for Waymo/nuScenes dataset) - [AFDet](https://arxiv.org/abs/2006.12671): another work inspired by CenterNet achieves good performance on KITTI/Waymo dataset - [mmdetection3d](https://github.com/open-mmlab/mmdetection3d/tree/master/configs/centerpoint): CenterPoint in mmdet framework - [CenterPointTensorRT](https://github.com/Abraham423/CenterPointTensorRT): CenterPoint-PointPillar for accelerated inference with TensorRT - [CenterPoint-ONNX](https://github.com/CarkusL/CenterPoint): Convert CenterPoint-Pillar to ONNX / TensorRT ## Use CenterPoint ### Installation Please refer to [INSTALL](docs/INSTALL.md) to set up libraries needed for distributed training and sparse convolution. ### Benchmark Evaluation and Training Please refer to [GETTING_START](docs/GETTING_START.md) to prepare the data.
