A Framework for Self-Training Perceptual Agents in Simulated Photorealistic Environments

摘要

The development of high-performance perception for mobile robotic agents is still challenging. Learning appropriate perception models usually requires extensive amounts of labeled training data that ideally follows the same distribution as the data an agent will encounter in its target task. Recent developments in gaming industry led to game engines able to generate photorealistic environments in real-time, which can be used to realistically simulate the sensory input of an agent.We propose a novel framework which allows the definition of different learning scenarios and instantiates these scenarios in a high quality game engine where a perceptual agent can act and learn in. The scenarios are specified in a newly developed scenario description language that allows the parametrization of the virtual environment and the perceptual agent. New scenarios can be sampled from a task-specific object distribution that allows the automatic generation of extensive amounts of different learning environments for the perceptual agent.We will demonstrate the plausibility of the framework by conducting object recognition experiments on a real robotic system which has been trained within our framework.
