Skeleton‐Based Posture Recognition for Home Care From Virtual Unmanned Aerial Vehicle

Expert Systems, Volume 42, Issue 9, September 2025.
ABSTRACT This article presents a novel approach for real‐time posture recognition in monitoring scenarios, utilising a virtual camera simulated on a UAV within virtual environments. Leveraging the MediaPipe Pose library, key points of the body skeleton are extracted, focusing on a subset of 8 key points for computational efficiency.
