OpenPCDet

OpenPCDet is a clear, simple, self-contained open source project for LiDAR-based 3D object detection.

It is also the official code release of [PointRCNN], [Part-A2-Net], [PV-RCNN], [Voxel R-CNN] and [PV-RCNN++].

Highlights:

  • OpenPCDet has been updated to v0.5.2 (Jan. 2022).
  • The codes of PV-RCNN++ has been supported.

Overview

Changelog

[2022-07-05] Added support for the 3D object detection backbone network Focals Conv.

[2022-02-12] Added support for using docker. Please refer to the guidance in ./docker.

[2022-02-07] Added support for Centerpoint models on Nuscenes Dataset.

[2022-01-14] Added support for dynamic pillar voxelization, following the implementation proposed in H^23D R-CNN with unique operation and torch_scatter package.

[2022-01-05] NEW: Update OpenPCDet to v0.5.2:

  • The code of PV-RCNN++ has been released to this repo, with higher performance, faster training/inference speed and less memory consumption than PV-RCNN.
  • Add performance of several models trained with full training set of Waymo Open Dataset.
  • Support Lyft dataset, see the pull request here.

[2021-12-09] NEW: Update OpenPCDet to v0.5.1:

  • Add PointPillar related baseline configs/results on Waymo Open Dataset.
  • Support Pandaset dataloader, see the pull request here.
  • Support a set of new augmentations, see the pull request here.

[2021-12-01] NEW: OpenPCDet v0.5.0 is released with the following features:

  • Improve the performance of all models on Waymo Open Dataset. Note that you need to re-prepare the training/validation data and ground-truth database of Waymo Open Dataset (see GETTING_STARTED.md).
  • Support anchor-free CenterHead, add configs of CenterPoint and PV-RCNN with CenterHead.
  • Support lastest PyTorch 1.1~1.10 and spconv 1.0~2.x, where spconv 2.x should be easy to install with pip and faster than previous version (see the official update of spconv here).
  • Support config USE_SHARED_MEMORY to use shared memory to potentially speed up the training process in case you suffer from an IO problem.
  • Support better and faster visualization script, and you need to install Open3D firstly.

[2021-06-08] Added support for the voxel-based 3D object detection model Voxel R-CNN.

[2021-05-14] Added support for the monocular 3D object detection model CaDDN.

[2020-11-27] Bugfixed: Please re-prepare the validation infos of Waymo dataset (version 1.2) if you would like to use our provided Waymo evaluation tool (see PR). Note that you do not need to re-prepare the training data and ground-truth database.

[2020-11-10] The Waymo Open Dataset has been supported with state-of-the-art results. Currently we provide the configs and results of SECOND, PartA2 and PV-RCNN on the Waymo Open Dataset, and more models could be easily supported by modifying their dataset configs.

[2020-08-10] Bugfixed: The provided NuScenes models have been updated to fix the loading bugs. Please redownload it if you need to use the pretrained NuScenes models.

[2020-07-30] OpenPCDet v0.3.0 is released with the following features:

[2020-07-17] Add simple visualization codes and a quick demo to test with custom data.

[2020-06-24] OpenPCDet v0.2.0 is released with pretty new structures to support more models and datasets.

[2020-03-16] OpenPCDet v0.1.0 is released.

Introduction

What does OpenPCDet toolbox do?

Note that we have upgrated PCDet from v0.1 to v0.2 with pretty new structures to support various datasets and models.

OpenPCDet is a general PyTorch-based codebase for 3D object detection from point cloud. It currently supports multiple state-of-the-art 3D object detection methods with highly refactored codes for both one-stage and two-stage 3D detection frameworks.

Based on OpenPCDet toolbox, we win the Waymo Open Dataset challenge in 3D Detection, 3D Tracking, Domain Adaptation three tracks among all LiDAR-only methods, and the Waymo related models will be released to OpenPCDet soon.

We are actively updating this repo currently, and more datasets and models will be supported soon. Contributions are also welcomed.

OpenPCDet design pattern

  • Data-Model separation with unified point cloud coordinate for easily extending to custom datasets:

  • Unified 3D box definition: (x, y, z, dx, dy, dz, heading).

  • Flexible and clear model structure to easily support various 3D detection models:

  • Support various models within one framework as:

Currently Supported Features

  • Support both one-stage and two-stage 3D object detection frameworks
  • Support distributed training & testing with multiple GPUs and multiple machines
  • Support multiple heads on different scales to detect different classes
  • Support stacked version set abstraction to encode various number of points in different scenes
  • Support Adaptive Training Sample Selection (ATSS) for target assignment
  • Support RoI-aware point cloud pooling & RoI-grid point cloud pooling
  • Support GPU version 3D IoU calculation and rotated NMS

Waymo Open Dataset Baselines

We provide the setting of DATA_CONFIG.SAMPLED_INTERVAL on the Waymo Open Dataset (WOD) to subsample partial samples for training and evaluation, so you could also play with WOD by setting a smaller DATA_CONFIG.SAMPLED_INTERVAL even if you only have limited GPU resources.

By default, all models are trained with a single frame of 20% data (~32k frames) of all the training samples on 8 GTX 1080Ti GPUs, and the results of each cell here are mAP/mAPH calculated by the official Waymo evaluation metrics on the whole validation set (version 1.2).

We could not provide the above pretrained models due to Waymo Dataset License Agreement, but you could easily achieve similar performance by training with the default configs.

Acknowledgement

OpenPCDet is an open source project for LiDAR-based 3D scene perception that supports multiple LiDAR-based perception models as shown above. Some parts of PCDet are learned from the official released codes of the above supported methods. We would like to thank for their proposed methods and the official implementation.

We hope that this repo could serve as a strong and flexible codebase to benefit the research community by speeding up the process of reimplementing previous works and/or developing new methods.
