Systems and methods of fall detection for elderly and patient are proposed. The general system includes four units: data acquisition, feature extraction, fall assessment and fall alert. A P-3D position calculation method is developed. Fall detection algorithm uses P-3D positions of head and body shape to identify fall. We disclose a way to generate 2D-3D lookup table.
