OpenLidarPercept

Introduction

OpenLidarPercept is an open source project for LiDAR-based 3D scene perception. As of now, it mainly consists of PCDet toolbox for 3D object detection from point cloud.

What does PCDet toolbox do?

PCDet 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.

It is also the official code release of [Part-A^2 net] and [PV-RCNN].

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

Currently Supported Features

• Unified point cloud coordinate and clear code structure and for supporting lots of datasets and approaches
• 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

Acknowledgement

OpenLidarPercept 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.
