AirSim is implemented as a plug-in of Unreal Engine. It makes full use of Unreal Engine’s ability to create a highly realistic and realistic virtual environment. It can simulate real-world environments such as shadows and reflections, and the virtual environment can easily generate a large amount of annotation data. At the same time, it provides a simple and convenient interface, which can allow drones and autonomous driving algorithms to access a large amount of training. The primary goal of AirSim is to serve as a platform for AI research to test end-to-end reinforcement learning algorithms for deep learning, computer vision, and autonomous vehicles. The latest AirSim also provides a version of the Unity engine that adds lidar support.
