Abstract

We have developed a visual sensing system for finding the elderly or sick people's paroxysm accidents in the lavatory. The system utilize our developed fiber grating vision sensor to get the 3D information of the person in the lavatory. A visual sensor installed on the ceiling watches the appearance of the person in the lavatory without disturbing his/her privacy. And the warning should be issued to his/her family or the staffs of the hospital in such a case that the system give a decision that the person falls senseless. This paper describes the configuration of the system for finding paroxysm accidents in lavatory using fiber grating vision sensor and the method for classify the states of the person in the lavatory. And, we installed our trial system in the model lavatory and performed an experiment assuming various situations in the lavatory. We think that we could obtain satisfactory determination precision regarding the external warning.
