Embodiment Construction

[0044] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0045] 1. System composition

[0046] like figure 1 As shown, this fall detection and alarm system of the present invention includes a data acquisition unit 1, which is composed of Kinect components, and is used to detect the motion state of the user 5; Kinect attitude adjustment unit 2, which is composed of pan-tilt components, is used for auxiliary data collection The unit changes the viewing angle; the data processing unit 3 is composed of a computer and a KinectSDK software module, which can process the data transmitted by the fall detection unit and obtain a user fall prompt; the data processing unit is connected with the Kinect attitude adjustment unit at the same time, and by analyzing The data carries out angle adjustment to Kinect posture adjustment unit; Alarm unit, is made of the computer of described data processing unit and alar...

Abstract

The invention relates to a fall detection and alarm system based on Kinect and an operating method thereof, and aims to realize interaction between activity information of old people and a computer in a noncontact mode using the functions of data detection and the like of bone nodes of Kinect and corresponding software and hardware. The method mainly comprises the steps of acquiring human bone data without influencing normal life of old people, acquiring three-dimensional coordinates of bone nodes, calculating the position and the speed of human gravity center in the space, and accurately detecting a fall by judging whether the human gravity action line exceeds a supporting surface range or not and the moving speed of the gravity center in the vertical direction and the horizontal direction. Moreover, an alarm is innovatively given in three modes including video call, deep image and color image transmission, and short message reminding. Finally, the fall detection and alarm system based on Kinect is completed by setting a holder automatically tracking a human body to rotate and compiling relevant software interfaces.

Description

technical field [0001] The invention relates to the field of family monitoring, in particular to the field of fall detection, in particular to a fall detection and alarm system. Background technique [0002] The current fall detection technology can be divided into the following types according to the different means of obtaining fall information: [0003] (1) User-initiated alarm system [0004] The user must not lose consciousness after the fall, have certain mobility, and the user cannot be an elderly person suffering from Alzheimer's or other mental illness. This makes falls in many cases undetectable and unrecognizable. [0005] (2) Wearable-based fall detection system [0006] This detection system can monitor the activities of the human body in real time. When the movement parameters of the human body change, it can judge whether a fall has occurred through an algorithm. However, this kind of system needs to be carried around, which is inconvenient and may affect ...
