FALL DETECTION AND REPORTING TECHNOLOGY

摘要

Fall detection and reporting technology, in which output from at least one sensor configured to sense, in a room of a building, activity associated with a patient falling is monitored and a determination is made to capture one or more images of the room based on the monitoring. An image of the room is captured with a camera positioned to include the patient within a field of view of the camera and the captured image of the room is analyzed to detect a state of the patient at a time of capturing the image. A potential fall event for the patient is determined based on the detected state of the patient and a message indicating the potential fall event for the patient is sent based on the determination of the potential fall event for the patient. Techniques are also described for fall detection and reporting using an on-body sensing device.

1. A method comprising:
determining to capture one or more images of an area; based on the determination to capture one or more images of the area, capturing, with a camera positioned to include a person within a field of view of the camera, an image of the area; analyzing the captured image of the area to detect a state of the person by:
performing image foreground segmentation on the captured image of the area to create a segmented image,performing template matching on the segmented image to identify a human shape in the segmented image, andcalculating a position and an orientation associated with the identified human shape in the segmented image; and determining, based on the calculated position and the calculated orientation associated with the identified human shape in the segmented image, a potential fall event for the person; and performing an operation directed to assisting the person with the potential fall event based on the determined potential fall event for the person.
