CARLA Simulator

CARLA is an open-source simulator for autonomous driving research. CARLA has been developed from the ground up to support development, training, and validation of autonomous driving systems. In addition to open-source code and protocols, CARLA provides open digital assets (urban layouts, buildings, vehicles) that were created for this purpose and can be used freely. The simulation platform supports flexible specification of sensor suites and environmental conditions.

[!NOTE] This is the development branch ue4-dev for the Unreal Engine 4.26 version of CARLA. This branch exists in parallel with the Unreal Engine 5.3 version of CARLA, in the ue5-dev branch. Please be sure that this version of CARLA is suitable for your needs as there are significant differences between the UE 4.26 and UE 5.3 versions of CARLA.

CARLA Dependency and Integration licenses

The ad-rss-lib library compiled and linked by the RSS Integration build variant introduces LGPL-2.1-only License.

Unreal Engine 4 follows its own license terms.

CARLA uses three dependencies as part of the SUMO integration:

• PROJ, a generic coordinate transformation software which uses the X/MIT open source license.
• SQLite, part of the PROJ dependencies, which is in the public domain.
• Xerces-C, a validating XML parser, which is made available under the Apache Software License, Version 2.0.

CARLA uses one dependency as part of the Chrono integration:

• Eigen, a C++ template library for linear algebra which uses the MPL2 license.

CARLA uses the Autodesk FBX SDK for converting FBX to OBJ in the import process of maps. This step is optional, and the SDK is located here
