CARLA-GENERATOR

This is a co-simulator for autonomous driving that can be used to generate KITTI-compatible and semantic3D-compatible datasets. If you want to realize real-time network simulation, please cooperate with our sub-module NS3-DSRC, NS3-NR-C-V2X.

If you are interested in error concealment, please visit our LiDAR Point Cloud Error Concealment System.

Installation

Requirements

All the codes are tested in the following environment:

• OS (Ubuntu 20.04 or Windows 10)
• CARLA 0.9.12
• Python 3.7.13+

Quick demo

a. Build environment

conda create -n carla-generator python==3.7.13 -y
conda activate carla-generator

b. Clone repository

git clone https://github.com/S-kewen/carla-generator
cd carla-generator
pip install -r requirements.txt

c. Install CARLA

We recommend using the binary release, you can also building CARLA from source code.

• Windows 10

curl -0 https://carla-releases.s3.eu-west-3.amazonaws.com/Windows/CARLA_0.9.12.zip --output CARLA_0.9.12.zip
tar -xf CARLA_0.9.12.zip
pip3 install WindowsNoEditor\PythonAPI\carla\dist\carla-0.9.12-cp37-cp37m-win_amd64.whl
WindowsNoEditor\CarlaUE4.exe

• Ubuntu 20.04

wget https://carla-releases.s3.eu-west-3.amazonaws.com/Linux/CARLA_0.9.12.tar.gz
tar -zxvf CARLA_0.9.12.tar.gz
cd CARLA_0.9.12
pip3 install CARLA_0.9.12/PythonAPI/carla/dist/carla-0.9.12-py3.7-linux-x86_64.egg
./CARLA_0.9.12/CarlaUE4.sh

d. Run

python generator.py --s NS3.ENABLE False # simple demo
python generator.py --s NS3.ENABLE True # with NS-3 simulator

For specific configuration, please refer to config.yaml.

Offline simulation

You also can store all the data and then run the NS-3 sub-module for network simulation.

python exp_offline_ns3.py --zmqPort {your_zmq_port} --path {your_dataset_path} --config {your_config_file}

Moreover, we support network simulation for the KITTI odometry dataset.

python exp_offline_ns3_kitti.py --zmqPort {your_zmq_port} --path {your_dataset_path} --config {your_config_file}

Limitations

We are happy to improve this project together, please submit your pull request if you fixed these limitations.

• Calib: Our sensors are installed in a fixed location and can not provide calibration replacement.
• LiDAR Intensity: The CARLA LiDAR sensor only provides virtual intensity without considering the material.
