Reproducing real-world traffic scenes in the simulator is fundamental to training self-driving systems. Creating a simulation scenario is a complex task, generally done manually: the ego-vehicle and other entities are placed and their trajectories defined, trying to recreate some situation found in real traffic. To reduce the manual burden, here we propose the Real-to-Synthetic toolset. This toolset provides synthetic traffic scene in openDrive format, which can be directly simulated in many simulators such as SUMO or CARLA. Also, we provide a scene generator which generates near-realistic scene from minimum user effort. To maintain the similarity between real-world scene and generated one, here we introduce the concept “Road Scene Graph”(RSG). In this graph, nodes represent entities while edges stand for pairwise relationships. These relationships could be maintained in the scene generation process while the actor is generated according to the distribution sampled from real-world data. Experiments proved that by using “Road Scene Graph”, our scene generator proposes a much more convenient way to conFigure traffic scenes rather than manually defining every actor’s initial status and trajectories.
