The Modelling and Simulation Tool provides a convenient system for generating
high-fidelity synthetic air-operations datasets including environment selection,
drone physics simulation and weather effects (e.g., wind, fog). The Tool utilizes
3D modelling environments, allows trajectory edition or waypoint selection,
implementation of drone physics behaviour and supports multiple sensor
configurations such as monocular or stereoscopic camera systems.
This tool uses Blender. It is a 3D open-source modelling and rendering engine
applied for synthetic dataset generation. It supports loading of several data
formats, supports animations, simulations and it is highly configurable. One of
the advantages is the ability to render photorealistic images using Cycles
render. Blender supports rendering into multiple cameras as well as configuring
the parameters of cameras such as focal length or radial distortion. Cameras are
connected to the 3D model of the UAV. After that, the centre of mass is animated
in such a way as to simulate a fly-through of the city. The Blender provides
tools for precise trajectory modelling and the trajectory can be exported to the
external file using scripts. The exported trajectory data of the generated
synthetic dataset is important for the evaluation of the accuracy of the
trajectory estimation algorithm which uses the generated images as an input and
the exported trajectory as a ground truth.
