摘要:

在本文中,我们提出了一个可推广的方法,系统地结合数据驱动MCMC samplingand推理使用基于规则的上下文知识的数据抽象。特别是,我们证明了我们的方法在室内环境中建立抽象语义地图的情况下的有用性。我们的系统的产品是一个参数化的抽象模型的感知环境,不仅准确地代表了环境的几何形状,但也提供了有价值的抽象信息,有利于高层次的机器人应用。基于预定义的抽象术语,如类型和关系,我们定义特定于任务的上下文知识作为马尔可夫逻辑网络的描述规则。相应的推理结果被用来构造一个先验分布,旨在增加合理的约束语义映射的解决方案空间。此外,通过应用语义注释的传感器模型,我们显式地使用上下文信息来解释传感器数据。在真实世界数据上的实验显示了良好的效果,从而证实了我们的系统的实用性。

英文摘要:

In this paper, we propose a generalizable method that systematically combines data driven MCMC samplingand inference using rule-based context knowledge for data abstraction. In particular, we demonstrate the usefulness of our method in the scenario of building abstract semantic maps for indoor environments. The product of our system is a parametric abstract model of the perceived environment that not only accurately represents the geometry of the environment but also provides valuable abstract information which benefits high-level robotic applications. Based on predefined abstract terms,such as type and relation, we define task-specific context knowledge as descriptive rules in Markov Logic Networks. The corresponding inference results are used to construct a priordistribution that aims to add reasonable constraints to the solution space of semantic maps. In addition, by applying a semantically annotated sensor model, we explicitly use context information to interpret the sensor data. Experiments on real world data show promising results and thus confirm the usefulness of our system.
