lidar_centerpoint
Purpose
lidar_centerpoint is a package for detecting dynamic 3D objects.
Inner-workings / Algorithms
In this implementation, CenterPoint [1] uses a PointPillars-based [2] network to inference with TensorRT.
We trained the models using https://github.com/open-mmlab/mmdetection3d.

shutdown the node after TensorRT engine file is built |
Assumptions / Known limits
- The
object.existence_probabilityis stored the value of classification confidence of a DNN, not probability.
Trained Models
You can download the onnx format of trained models by clicking on the links below.
- Centerpoint : pts_voxel_encoder_centerpoint.onnx, pts_backbone_neck_head_centerpoint.onnx
- Centerpoint tiny: pts_voxel_encoder_centerpoint_tiny.onnx, pts_backbone_neck_head_centerpoint_tiny.onnx
Centerpoint was trained in nuScenes (~28k lidar frames) [8] and TIER IV’s internal database (~11k lidar frames) for 60 epochs.
Centerpoint tiny was trained in Argoverse 2 (~110k lidar frames) [9] and TIER IV’s internal database (~11k lidar frames) for 20 epochs.
Standalone inference and visualization
In addition to its use as a standard ROS node, lidar_centerpoint can also be used to perform inferences in an isolated manner.
To do so, execute the following launcher, where pcd_path is the path of the pointcloud to be used for inference.
ros2 launch lidar_centerpoint single_inference_lidar_centerpoint.launch.xml pcd_path:=test_pointcloud.pcd detections_path:=test_detections.ply
lidar_centerpoint generates a ply file in the provided detections_path, which contains the detections as triangle meshes.
These detections can be visualized by most 3D tools, but we also integrate a visualization UI using Open3D which is launched alongside lidar_centerpoint.
Changelog
v1 (2022/07/06)
| Name | URLs | Description |
|---|---|---|
centerpoint |
pts_voxel_encoder pts_backbone_neck_head |
There is a single change due to the limitation in the implementation of this package. num_filters=[32, 32] of PillarFeatureNet
|
centerpoint_tiny |
pts_voxel_encoder pts_backbone_neck_head |

These changes are compared with this configuration.
v0 (2021/12/03)
| Name | URLs | Description |
|---|---|---|
default |
pts_voxel_encoder pts_backbone_neck_head |
