Fall-over alarming method, device and equipment

Abstract

The invention provides a fall-over alarming method, device and equipment, and relates to the field of fall-over monitoring. The method is used for the device. The equipment comprises the device. The method comprises the following steps: acquiring an environment video in an acquiring region; processing the environment video into a plurality of frames of first image sequences; inputting each frame of first image sequences into a human body attitude estimation model based on a deep learning algorithm to obtain a heat image corresponding to human bodies in the environment video; acquiring a plurality of key points of the heat image, and generating a first key point sequence by the key points according to a preset rule; judging whether a human body falls over or not according to the first key point sequence corresponding to the frames of continuous first image sequences; and when determining that the human body falls over, generating alarming information. The human bodies in the environment video are acquired, change of attitudes of the human bodies is acquired, when determining that the human body falls over, the device generates the alarming information, a person does not need to wear the device, and the states of the human bodies can be detected while activity of the human bodies is not affected.

Description

technical field [0001] The invention relates to the field of fall prevention monitoring, in particular to a fall alarm method, device and equipment. Background technique [0002] According to the statistics of the World Organization for Disease Control and Prevention, 1 / 3 of the elderly over 65 years old in the world will fall every year, half of which are recurrent falls, and the rate of falls increases with age; the elderly who fall Moderate and severe injuries (hip fractures and head trauma) occur in 20%-30% of people, and 60% of them are limited or unable to move, resulting in huge medical burden and health damage. In the hospital, if a patient falls and is not treated in time, there will be serious consequences. It has become a new research hotspot in the world to reduce the injury caused by falls of the elderly and patients. Medical research shows that reducing the impact on the body when a person falls can effectively reduce the injury caused by a fall accident; and...

Problems solved by technology

[0004] However, the limitation of needing to wear additional equipment has greatly hindered the realization of the existing solutions, and the equipment is more cumbersome to wear. It is not easy for the elderly or patients to operate if they have not been in contact with such devices before, and there are strict requirements for the wearing position of the equipment. Ordinary people are not easy to master, and may require additional professionals to install on-site

In addition, most of the elderly or patients have limited mobility, and it is likely that they have not had time to wear the device due to their physical condition. Once danger occurs, the consequences will be disastrous if they cannot call the police in time. The device needs to be worn 24 hours a day, which affects the comfort of the elderly and the sick
