Safety monitoring system based on omnidirectional vision for old people living alone

Abstract

A safety monitoring system based on omnidirectional vision for old people living alone comprises an omnidirectional vision camera device and a microprocessor for analyzing, processing and determining activity quantity, postures, falling and daily behavior habits of the old people living alone according to full view images filmed by the omnidirectional vision camera device and relevant input information. The omnidirectional camera device is arranged above the middle of a living room of the old people living alone and can capture more than 80% daily activity video images of the old people. By means of computer vision, locating, tracking and identification of human bodies are conducted, and activity quantity, postures, movement behavior and daily life of the older people living alone are analyzed and determined. The safety monitoring system can not only automatically detect important matters of the older people within an indoor visual range such as falling and the like, but also can intelligently determine abnormal behaviors of the old people outside the visual range and when the old people go out, thereby providing a means of remote monitoring for the old people living alone.
