3D-LiDAR Detection

Personal project at Baram, Academic group
Division of Robotics, Kwangwoon University at Seoul, Korea
Term: 09.2021. ~ 11.2021.
Intro: 3D-LiDAR Detection with SVL Simulator

OS: Ubuntu 18.04
GPU spec: RTX2070(laptop)
Programming Language: Python
Development Environment: ROS Melodic

* Origin source: This project is based on OpenPCDet


For object detecting, we use camera generally. But in my sight, camera have many limitation. Representatively, light is one of the biggest problems in image processing. But some companies are try to complete vision task only with camera, for example, Tesla.(dogecoin forever, go to the Mars) Whatever, now, I face two routes. One is fight to overcome the limitation of camera(like Tesla), and the other one is use another sensor. Last year, I tried object detection with camera. In this project, so I decided trying other route and aimed object detecting with 3D-LiDAR.

An open source, OpenPCDet supply basic 3D-LiDAR object detection code with pre-trained models. I used this source and for input data, used sensor data from SVL Simulator.

Every task is worked on ROS Melodic environment. SVL Simulator supply ros bridge, so can adapt simulation to ROS easily. In ROS environment, get 3D-LiDAR data first, and put them to detection network. Now, with ROS visulazation tool rviz, we can check results.

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-A^2 net], [PV-RCNN] and [Voxel R-CNN].

Overview

Changelog

[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] NEW: 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

Model Zoo

KITTI 3D Object Detection Baselines

Selected supported methods are shown in the below table. The results are the 3D detection performance of moderate difficulty on the val set of KITTI dataset.

  • All models are trained with 8 GTX 1080Ti GPUs and are available for download.
  • The training time is measured with 8 TITAN XP GPUs and PyTorch 1.5.

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 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.

Other datasets

More datasets are on the way.
