Abstract: Observing human activities can reveal a lot about the structure of the environment, the objects contained therein and also their functionality. This knowledge, in turn, can be useful for robots interacting with humans or for robots performing mobile manipulation tasks. In this paper, we present an approach to infer the geometric and functional structure of the environment and the position of certain relevant objects in it from human activity. We observe this activity using a full-body motion capture system consisting of a set of inertial measurement units. This is a hard problem since our data suit provides odometry estimates only, which severely drift over time. Therefore, we regard the objects inferred from the activities as landmarks in a graph-based simultaneous localization and mapping problem, which we optimize to obtain accurate estimates about the poses of the objects and the trajectory of the human. In extensive experiments, we demonstrate the effectiveness of the proposed method for the reconstruction of 3D representations. The resulting models not only contain a geometric but also a functional description of the environment and naturally provide a segmentation into individual objects.
