Unreal engine

Unreal Engine is a real-time 3D computer graphics game engine developed by Epic Games that serves as a software framework for creating video games, virtual reality experiences, simulations, and visual effects. Originally launched in 1998, it has expanded beyond interactive entertainment into industries such as film and television production, architectural visualization, robotics, and automotive development. The platform provides an integrated suite of creation tools for advanced rendering, physics simulation, lighting, animation, and visual scripting, enabling developers to build photorealistic and highly responsive interactive environments across multiple hardware platforms.

Why you should read this

Presents AirSim, an Unreal Engine-based simulator that combines high-frequency physics and photorealistic environments to enable real-time hardware-in-the-loop testing and large-scale data generation for autonomous vehicles.

Developing and testing algorithms for autonomous vehicles in real world is an expensive and time consuming process. Also, in order to utilize recent advances in machine intelligence and deep learning we need to collect a large amount of annotated training data in a variety of conditions and environments. We present a new simulator built on Unreal Engine that offers physically and visually realistic simulations for both of these goals. Our simulator includes a physics engine that can operate at a high frequency for real-time hardware-in-the-loop (HITL) simulations with support for popular protocols (e.g. MavLink). The simulator is designed from the ground up to be extensible to accommodate new types of vehicles, hardware platforms and software protocols. In addition, the modular design enables various components to be easily usable independently in other projects. We demonstrate the simulator by first implementing a quadrotor as an autonomous vehicle and then experimentally comparing the software components with real-world flights.
