Changelog

[2020-08-10] NEW: 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] NEW: OpenPCDet v0.3.0 is released with the following features:

• The Point-based and Anchor-Free models (PointRCNN, PartA2-Free) are supported now.
• The NuScenes dataset is supported with strong baseline results (SECOND-MultiHead (CBGS) and PointPillar-MultiHead).
• High efficiency than last version, support PyTorch 1.1~1.5 and spconv 1.0~1.2 simultaneously.

[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

Model Zoo

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.
