The MINDFUL Unreal Engine Based UAV Repository (UEUAVSim) contains examples demonstrating how to use Unreal Engine with simulated data workflows. It currently includes "3D Point Cloud Reconstruction with AirSim" and "Unreal Engine 4 Basic Simulated Data Collection Tutorial".
AirSim can be used to collect and reconstruct 3D point clouds using Unreal Engine. This tutorial describes how to set up your environment to collect data, either manually or from a list of pre-scripted waypoints, and reconstruct a 3D point cloud from a sequence of color and depth images, along with the corresponding camera poses. The resulting data is visualized using Open3D and can be used for a variety of research applications.
This tutorial describes how to setup and collect data using only the native Unreal Engine 4 tools and the Movie Render Plugin. This could be used to easily standup data collections to facilitate machine learning, computer vision, robotics, or any other project that can make use of the simulated imagery.
