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

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.

Health cognitive system under self-excitation and feedback control

The invention provides a health cognition system under self-excitation and feedback control. The system comprises a balance ability evaluation subsystem, a self-excitation subsystem, a feedback control subsystem and a health exercise device, wherein the health exercise device is connected with the balance ability evaluation subsystem and used for collecting health exercise parameters in the healthexercise process of a patient; excitation scene videos corresponding to different balance ability scores are stored in an excitation database of the self-excitation subsystem, and the excitation scene videos are augmented reality (AR) scenes capable of exciting patients with different balance abilities to complete various daily life activity operations and achieving the effects of the daily lifeactivity operations. According to a technical scheme in the invention, a visualization technology and excitation factors are introduced into the rehabilitation exercise process of stroke patients, theinteraction relationship between the stroke patients and the health cognition system is improved, more convenient, easier and relaxed use experience is brought to users, and the stroke patients can be immersed in a positive and optimistic rehabilitation environment.

Urban community specific person behavior chain dynamic identification and prediction evaluation method and system

The invention discloses an urban community specific person behavior chain dynamic identification and prediction evaluation method and system, and belongs to the technical field of application information. The method comprises the following steps of: 1, simulating daily activities of specific persons in an urban community by using a multi-agent simulation technology; 2, based on the simulation result in the step 1, establishing a behavior chain library of specific persons in the urban community in different behavior modes; 3, acquiring trajectory data of the specific persons by using Internet-of-things sensing equipment, performing trajectory calibration and serialized modeling, and establishing behavior chains; and 4, searching similar complete behavior chains in the behavior chain libraryaccording to the space-time similarity among the behavior chains, carrying out updating, and optimizing a search result to realize dynamic identification and prediction evaluation of the behavior chains of the specific persons in the urban community. The system is used for realizing the method. Technical support is provided for specific person management and control work of a community public security management department. Dynamic identification and prediction evaluation are carried out on the behavior chains of the specific persons.
