CARLA Simulator

CARLA is a simulator for self-driving cars.

Getting Started

Installation

Follow the steps at QuickStart.

pip install --user pygame numpy
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 92635A407F7A020C
sudo add-apt-repository "deb [arch=amd64 trusted=yes] http://dist.carla.org/carla-0.9.9/ all main"
sudo apt-get update
sudo apt-get install carla-simulator
cd /opt/carla-simulator

Running a simulation

Start the server by running /opt/carla-simulator/bin/CarlaUE4.sh

Now you will need to write a client in Python. The client handles setting up the scene and all sensor data. See Tutorial: Retrieve Data and scroll down to tutorial_ego.py.

Fixed time step

Reference

Normal games run at realtime, i.e. frames are generated as fast as possble (or limited by vsync) and the time between frames set based on the elapsed time. For demos and games, this is fine. However for simulations, you will want to fix the time between frames to a constant value.

./CarlaUE4.sh -benchmark -fps=30
