Abstract
We present a method that allows autonomous systems to detect anomalous events in human-populated environments through understating of their structure and how they change over time. We represent the environment by temporary warped space-hypertime continuous models derived from patterns of changes driven by human activities within the observed space. The ability of the method to detect anomalies is evaluated on real-world datasets gathered by robots over the course of several weeks. An earlier version of this approach was already applied to robots that patrolled offices of a global security company (G4S).
The work has been supported by the Czech Science Foundation project 17-27006Y, MŠMT project FR-8J18FR018 and PHC Barrande project 40682ZH (3L4AV). We thank the School of Computer Science, University of Lincoln, UK for providing us with the data, namely Dr Grzegorz Cielniak for being the long-suffering, but tolerant experimental human subject.
