Abstract:
To provide a watching system with which it is possible to sense in early stages that the person being watched is about to enter a dangerous action in a bed and prevent an accident in and around the bed.SOLUTION: Provided is a watching system for detecting the getting-out-of-bed behavior of the person being watched who lies down along the long side of a rectangular bed, with the head placed on a predetermined short side of the bed. The watching system comprises: a thermal image information acquisition unit TG for acquiring data that indicates a temperature distribution in a prescribed area as thermal image information and having an infrared array sensor substrate on which a plurality of thermopile elements are arrayed in matrix form; and a getting-out-of-bed behavior determination unit GJ for determining the getting-out-of-bed behavior of the person being watched, on the basis of the thermal image information acquired by the thermal image information acquisition unit TG. The thermal image information acquisition unit TG is arranged at a position downward of the ceiling so that the back and both arms of the person being watched having gotten out of bed turning the back to the short side are captured from behind and thermal image information is acquired.SELECTED DRAWING: Figure 5
