INFORMATION PROCESSING APPARATUS FOR WATCHING, INFORMATION PROCESSING METHOD AND NON-TRANSITORY RECORDING MEDIUM RECORDED WITH PROGRAM
An information processing apparatus according to one aspect of the present invention is disclosed, which includes an image acquiring unit acquiring moving images captured as images of a watching target person and a target object as a reference for the behavior thereof, a moving object detecting unit detecting a moving-object area with a motion occurring from the moving images, and a behavior presuming unit presuming a behavior of the watching target person about the target object corresponding to a positional relationship between a target object area set within the moving images and the detected moving-object area.
1 . An information processing apparatus comprising:
an image acquiring unit to acquire moving images captured as an image of a watching target person whose behavior is watched and an image of a target object serving as a reference for the behavior of the watching target person;
a moving object detecting unit to detect a moving-object area where a motion occurs from within the acquired moving images; and
a behavior presuming unit to presume a behavior of the watching target person with respect to the target object in accordance with a positional relationship between a target object area set within the moving images as an area where the target object exists and the detected moving-object area.
2 . The information processing apparatus according to claim 1 , wherein the behavior presuming unit presumes the behavior of the watching target person with respect to the target object further in accordance with a size of the detected moving-object area.
3 . The information processing apparatus according to claim 1 , wherein the moving object detecting unit detects the moving-object area from within a detection area set as area for presuming the behavior of the watching target person in the acquired moving images.
4 . The information processing apparatus according to claim 3 , wherein the moving object detecting unit detects the moving-object area from within the detection area determined based on types of the behaviors of the watching target person that are to be presumed.
5 . The information processing apparatus according to claim 1 , wherein the image acquiring unit acquires the moving image captured as an image of a bed defined as the target object, and
the behavior presuming unit presumes at least any one of the behaviors of the watching target person such as a get-up state on the bed, a sitting-on-bed-edge state, an over-bed-fence state, a come-down state from the bed and a leaving-bed state.
6 . The information processing apparatus according to claim 1 , further comprising a notifying unit to notify, when the presumed behavior of the watching target person is a behavior indicating the symptom that the watching target person will encounter with an impending danger, a watcher to watch the watching target person of this symptom.
7 . An information processing method by which a computer executes:
acquiring moving images captured as an image of a watching target person whose behavior is watched and an image of a target object serving as a reference for the behavior of the watching target person;
detecting a moving-object area where a motion occurs from within the acquired moving images; and
presuming a behavior of the watching target person with respect to the target object in accordance with a positional relationship between a target object area set within the moving images as an area where the target object exists and the detected moving-object area.
8 . A non-transitory recording medium recording a program to make a computer execute:
acquiring moving images captured as an image of a watching target person whose behavior is watched and an image of a target object serving as a reference for the behavior of the watching target person;
detecting a moving-object area where a motion occurs from within the acquired moving images; and
presuming a behavior of the watching target person with respect to the target object in accordance with a positional relationship between a target object area set within the moving images as an area where the target object exists and the detected moving-object area.
