The SPHERE project: Sleep monitoring using computer vision

The aim of the SPHERE project is to develop a compact
device that monitors sleep using computer vision. Our system
attaches to the ceiling above the bed and integrates infrared and
depth cameras, alongside other auxiliary sensors. We installed
systems in a nursery home and a sleep laboratory, allowing us to
evaluate algorithms that analyze respiration, sleep position and
agitation. Compared to other sleep monitoring modalities, computer
vision is non-intrusive, and provides a holistic understanding
of the bed environment, enabling better alarm systems and
cleaner sleep summaries.
