A Robotic Context Query-Processing Framework Based on Spatio-Temporal Context Ontology Open
Service robots operating in indoor environments should recognize dynamic changes from sensors, such as RGB-depth (RGB-D) cameras, and recall the past context. Therefore, we propose a context query-processing framework, comprising spatio-te…
