<h3> [AAAI2024] Expanding the Horizon for Surround-view 3D Object Detection </h3>
</div>

[![PWC](https://img.shields.io/endpoint.svg?url=https://paperswithcode.com/badge/far3d-expanding-the-horizon-for-surround-view/3d-object-detection-on-nuscenes-camera-only)](https://paperswithcode.com/sota/3d-object-detection-on-nuscenes-camera-only?p=far3d-expanding-the-horizon-for-surround-view)
[![arXiv](https://img.shields.io/badge/arXiv-Paper-<COLOR>.svg)](https://arxiv.org/abs/2308.09616)

## Introduction

This repository is an official implementation of Far3D.
![](figs/framework.png)

Expanding existing methods directly to cover long distances poses challenges such as heavy computation costs and unstable convergence. 
To address these limitations, we proposes a novel sparse query-based framework, dubbed Far3D. By utilizing high-quality 2D object priors, we generate 3D adaptive queries that complement the 3D global queries.
To efficiently capture discriminative features across different views and scales for long-range objects, we introduce a perspective-aware aggregation module. Additionally, we propose a range-modulated 3D denoising approach to address query error propagation and mitigate convergence issues in long-range tasks.

## News
- [2023/08/01] We release the paper on [Arxiv]((https://arxiv.org/abs/2308.09616)).  
- [2023/08/01] Far3D achieves comparable performance (31.6 mAP, 23.9 CDS) on long-range Argoverse2 dataset, as well as achieving SoTA performance (63.5 mAP, 68.7 NDS) on nuScenes Camera Only.

## Getting Started
Our pipeline follows [StreamPETR](https://github.com/exiawsh/StreamPETR), and you can follow [Get Started](./docs/get_started.md) step by step.
* If you have used StreamPETR before, it is easy to run Far3D without additional extensive installation.

Quick Train & Evaluation

Train the model
```angular2html
tools/dist_train.sh projects/configs/far3d.py 8 --work-dir work_dirs/far3d/
```
Evaluation
```angular2html
tools/dist_test.sh projects/configs/far3d.py work_dirs/far3d/iter_82548.pth 8 --eval bbox
```

**Notes**
- [This config](projects/configs/far3d.py) can be used to reproduce the results on Argoverse 2.
- For nuScenes version, due to the inconsistent data and evaluation processes, we do not incorporate it to this repo. One can transfer our model part to StreamPETR repo for nuScenes dataset.

FILE: docs/get_started.md
================================================
# Get Started
Note our Far3D inherit from the repo of [StreamPETR](https://github.com/exiawsh/StreamPETR/), thus many parts can be used in similar style. 

## 1. Setup
Please following [Setup instructions](https://github.com/exiawsh/StreamPETR/blob/main/docs/setup.md) to build environment and compile mmdet3d. We also provide detailed conda environment file [here](../py38.yaml).

**Instruction Steps**
1. Create a conda virtual environment and activate it.
2. Install PyTorch and torchvision following the official instructions.
3. Install flash-attn (optional).
4. Clone Far3D.
5. Install mmdet3d.

## 2. Data preparation
We use Argoverse 2 dataset and NuScenes dataset for experiments.
- NuScenes dataset preparation can refer to [Preparation](https://github.com/exiawsh/StreamPETR/blob/main/docs/data_preparation.md).
- Similarly, after downloading [Argoverse 2 sensor dataset](https://www.argoverse.org/av2.html#download-link), it can be processed following above pipelines and [create_av2_infos.py](../tools/create_infos_av2/create_av2_infos.py).
```angular2html
# first modify args such as split, dataset_dir.
python tools/create_infos_av2/gather_argo2_anno_feather.py
python tools/create_infos_av2/create_av2_infos.py
```

**Notes**: 
- Due to the huge strorage of Argoverse 2 dataset, we read data from s3 path. If any need to load from local disk or other paths, please modify [AV2LoadMultiViewImageFromFiles](../projects/mmdet3d_plugin/datasets/pipelines/custom_pipeline.py) for your convenience.
- For Argoverse 2, its 3D labels are in ego coordinates. The ego-motion transformation refer to [Argoverse2DatasetT](projects/mmdet3d_plugin/datasets/argoverse2_dataset_t.py).

## 3. Training & Inference
Train the model
```angular2html
tools/dist_train.sh projects/configs/far3d.py 8 --work-dir work_dirs/far3d/
```
Evaluation
```angular2html
tools/dist_test.sh projects/configs/far3d.py work_dirs/far3d/iter_82548.pth 8 --eval bbox
```
* You can also refer to [StreamPETR](https://github.com/exiawsh/StreamPETR/blob/main/docs/training_inference.md) for more training recipes.
