Embodiment 1

[0019] Example 1: Please refer to the attached figure 1 , a fall detection system, including a power supply 10, a general processor 20, a fall detection device 30, a voice alarm device 40, and a remote guardian terminal 50, wherein the general processor 20 is connected to the power supply 10, the The fall detection device 30, the voice alarm device 40, and the remote guardian terminal 50 are connected.

[0020] The connection is an electrical connection, and the power supply 10 is an independent power supply, which can ensure the entire independent power supply of the detection system.

Embodiment 2

[0021] Embodiment 2: Please refer to the attached figure 1 - attached figure 2 , a fall detection system, the basic structure is the same as that of Embodiment 1, the difference is that the fall detection device 30 includes a first axis capture camera 31, a second axis capture camera 32, a third axis capture camera 33. The first axis capture camera 31, the second axis capture camera 32, and the third axis capture camera 33 are respectively located at the upper, middle, and lower parts of the corners of the target activity space area, and are used to capture image data of different positions of the human body and Relevant data is sent to general processor 20, and described camera all adopts 3D camera, and described general processor 20 is connected with described fall detection device 30 as first axis capture camera 31, second axis capture camera 32, The third axis capture camera 33 is connected with the general processor 20 .

[0022] The general processor 20 receives the i...

Embodiment 3

[0023] Embodiment 3: Please refer to the attached figure 1 - attached image 3 . A fall detection method comprising,

[0024] (1) Image acquisition step, capture the image data within the scope of the target activity space area by the first axis capture camera 31, the second axis capture camera 32, and the third axis capture camera 33 of the fall detection device 30, and store the image data transmitted to the general processor 20;

[0025] (2) In the mirror detection step, the general processor 20 performs background difference calculation on the image data acquired by the first axis capture camera 31, the second axis capture camera 32, and the third axis capture camera 33 respectively, after calculation, when the first When the image data of the axis capture camera, the second axis capture camera, and the third axis capture camera simultaneously detect that someone enters the range of the target activity space area, fall detection is started;

[0026] (3) Fall detection ...

Abstract

A fall detection system includes a power source, a main processor, a fall detector, a voice alarm device and a remote guardian terminal, wherein the main processor is connected with the power source,the fall detector, the voice alarm device and the remote guardian terminal; the fall detector comprises a first axis capture camera, a second axis capture camera, a third axis capture camera which arerespectively located at the upper part, the middle part, and the lower part of a target movement space area and are connected with the main processor. By axis division of human body characteristics,whether there is a fall scene or not is judged in association with included angles between three axes and the horizontal plane, so that a problem that the false judgment rate of fall detection is toohigh is solved effectively. Fall risks of the elderly living alone are detected accurately and a safety alarm can be sent out timely.

Description

technical field [0001] The invention relates to the field of safety detection, in particular to a fall detection system and method. Background technique [0002] At present, with the deepening of the aging society, there are more and more empty-nesters, which has become a social problem that cannot be ignored. Empty-nesters live alone because they have no children to take care of. Elderly people living alone are prone to falls due to age factors. If the elderly fall and are not sent to the hospital for treatment in time, there will be a high rate of disability and hospitalization, which has brought huge costs to the family. Timely awareness and rescue of the elderly living alone who have fallen can buy valuable time for timely treatment and effectively reduce the disability rate. [0003] Although there are many methods for elderly fall detection, they are mainly wearable sensor detection methods, such as CN107909771A, a wireless sensor network-based personnel fall alarm sy...
