Abstract
A monitoring system includes one or more cameras to determine a three dimensional (3D) model of a person; means to detect a dangerous condition based on the 3D model; and means to generate a warning when the dangerous condition is detected.
Claims22
A monitoring system, comprising:
- one or more cameras to determine a three dimensional (3D) body model of a person;
- a processor coupled to the one or more cameras to process the 3D body model to detect a dangerous condition based on the 3D model with computer readable code to detect the person's fall including:
- computer readable code to detect a falling speed of the person's center-of-mass (threshold 1);
- computer readable code to detect when a body part touches a floor;
- and
- computer readable code to detect a time span without center-of-mass motion after fall (threshold 2);
- and
- a device to generate a warning when the dangerous condition is detected.

A monitoring system, comprising:
- one or more cameras to determine a three diminsinonal (3D) body model of a person;
- a processor coupled to the one or more cameras to process the 3D body model to detect a dangerous condition based on the 3D model;
- a device to generate a warning when the dangerous condition is detected;

6 more elements
A monitoring system, comprising:
- one or more cameras positioned to capture three dimensional (3D) body model of the patient;
- and
- a server coupled to the one or more cameras, the server executing code to process the 3D model, to detect a dangerous condition for the patient based on a center of mass of the 3D body model and to allow a remote third party to view images of the patient when the dangerous condition is detected, the code including:
- computer readable code to detect a falling speed of the person's center-of-mass (threshold 1);
- computer readable code to detect when a body part touches a floor;
- and
- computer readable code to detect a time span without center-of-mass motion after fall (threshold 2).
