Scenario Simulation

Author scenes, generate sensor data, test algorithms in simulated environments

Simulation using realistic unmanned aerial vehicle (UAV) scenarios and sensor models is a crucial part of testing UAV algorithms. UAV Toolbox provides two simulation environments in which to test these algorithms. Both environments have their uses, and one environment is not a replacement for the other.

  • In the cuboid simulation environment, vehicles and other platforms in the scenario are represented as simple box shapes, or for lidar applications, as polygon meshes. Use this environment to rapidly author scenarios or generate sensor data. Test controllers, tracking algorithms, and sensor fusion algorithms in both MATLAB® and Simulink®. To get started authoring a scenario, use the uavScenario object.

  • In the Unreal Engine® simulation environment, scenarios are rendered using the Unreal Engine from Epic Games®. Use this environment to visualize scenarios using more realistic graphics; to generate high-fidelity radar, camera, and lidar sensor data; and to test perception-in-the-loop systems. This environment is available in Simulink and runs on Windows® only. To learn more, see Unreal Engine Simulation for Unmanned Aerial Vehicles.
