# OccupancyM3D

### Note that this is an initial version, this repository needs to be further cleaned and refactored.

paper link: [[2305.15694] Learning Occupancy for Monocular 3D Object Detection](https://arxiv.org/abs/2305.15694)

## Installation

We employ the design and framework of  OpenPCDet, and follows the base setup in CaDDN, thanks for their great work!

Therefore, please follow the installation steps in [OpenPCDet](./OpenPCDet/README.md).

## Getting Started

First, please follow the KITTI data file generation in [CaDDN](https://github.com/TRAILab/CaDDN/blob/master/docs/GETTING_STARTED.md). You can find "depth_caddn" in [CaDDN](https://drive.google.com/file/d/1qFZux7KC_gJ0UHEg-qGJKqteE9Ivojin/view?usp=sharing), and "lidar_depth" in [Google Drive](https://drive.google.com/file/d/1fR2wKWYtioFOE38xrTXIO1bHKekbfxOI/view?usp=sharing).

We do not use the heavy deeplibV3 backbone. Instead, we use the pre-trained dla34 backbone from [DD3D](https://github.com/TRI-ML/dd3d). Note that the authors slightly modify the model. We re-map the key and provide it at [Google Drive](https://drive.google.com/file/d/1VRUFk0Bwwz60cDrgqbIHXaWubjFCPWKk/view?usp=sharing).

Then, train the model:

```shell
cd OccupancyM3D/OpenPCDet/tools

CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --rdzv_endpoint=localhost:6400 --nproc_per_node=4  train.py --launcher pytorch  --cfg_file ./cfgs/kitti_models/OccupancyM3D.yaml \
  --sync_bn --workers 4 \
  --num_epochs_to_eval 20  \
  --extra_tag OccupancyM3D
```

Eval the model using the pre-trained model:
```shell
CUDA_VISIBLE_DEVICES=0 python test.py --cfg_file ./cfgs/kitti_models/OccupancyM3D.yaml \
  --extra_tag val \
  --batch_size 2 --workers 4 \
  --ckpt $pre-trained-model-path
```

## Pretrained Model

To ease the usage, we provide the pre-trained model at: [Google Drive](https://drive.google.com/file/d/1PBrpNVypZMNY3l2fPOs4LoVwQwep0u45/view?usp=sharing)

Here we give the comparison.
