## Installation
Install the required environments with the requirements.txt file using [ANACONDA](https://www.anaconda.com/products/individual)
```
$ conda env create -f requirements.yml
```

## Command line
### Download the target model
You can find the model through the [official Baidu Apollo GitHub](https://github.com/ApolloAuto/apollo) and [YOLO website](https://pjreddie.com/darknet/yolo/). Or you can download the model [here](https://drive.google.com/file/d/17Eg1ySmucr1UQfye5wxAgGpv6VN5R0FP/view?usp=sharing) and then unzip it to `./data` folder.

### Generating the adversarial object

```
python attack.py [-obj] [-obj_save] [-lidar] [-cam] [-cali] [-e] [-o] [-it]
```

| Argument | Description |
| -------- | ----------- |
| `-e` | Constrained max changing for the object vetex|
|`-o` | Optimization method: pgd and adam |
|`-it` | Max iteration number |
|`-obj` | Initial benign 3D object path |
|`-obj_save` | Adversarial 3D object saving dir |
|`-lidar` | LiDAR point cloud data path |
|`-cam` | Camera image data path |
|`-cali` | Calibration file path |

### Example for generating the adversarial object

```
python attack.py -obj ./object/object.ply -obj_save ./object/obj_save -lidar ./data/lidar.bin -cam ./data/cam.png -cali ./data/cali.txt -e 0.2 -o pgd -it 1000
```

### Evaluation
The source code for evaluating the generated adversarial 3D object are in evaluation folder.
