Figure 1: Overview of UrbanScene3D.
We present a large scale urban scene dataset associated with a handy simulator based on Unreal Engine 4 and AirSim, which consists of both man-made and real-world reconstruction scenes in different scales, referred to as UrbanScene3D . The manually made scene models have compact structures, which are carefully constructed/designed by professional modelers according to the images and maps of target areas; see the first row of Figure 1 for a glance. In contrast, UrbanScene3D also offers dense, detailed scene models reconstructed by aerial images through multi-view stereo (MVS) techniques. These scenes have realistic textures and meticulous structures; see e.g., the second row of Figure 1. We have also released the originally captured aerial images that have been used to reconstruct the 3D scene models, as well as a set of 4K video sequences, all of which would facilitate designing algorithms, such SLAM and MVS; please check some samples shown in the third and fourth rows of Figure 1.
Video 1: Touring a virtual city scene. Note that users can obtain the corresponding CAD models associated with instance segmentation.
Video 2: Touring the real-world scenes. Note that these scenes are reconstructed by real-world aerial images, thus they have detailed geometries, structures and realistic textures. The instance segmentation is available as well.
Video 3: A real-world model reconstructed with aerial images captured from optimized 3D views.
Video 4: A sample of aerial videos aimed at 3D urban scene acquisition.
Video 5: Applications of our dataset and simulator, e.g., autonomous driving, drone navigation, and intelligent aerial acquisition.

The released zip file contains the unreal project of the above proposed urban scenes. As Video 5 shown, users can use either pure Unreal Engine or AirSim client (both in C++ or python) to capture their desired data. The ground truth textured meshes and their relevant poses are also provided in the Unreal project.
Required packages:
- Unreal Engine 4 (4.24 is recommended)
- C++ or Python
- AirSim(Optional)
