Method for monitoring abnormal behaviors of elderly people living alone in family environment

Abstract

The invention discloses a method for monitoring abnormal behaviors of elderly people living alone in a family environment, and belongs to the technical field of video images. The method includes the first step of carrying out infrared camera shooting by means of an infrared camera to obtain a video picture signal, the second step of carrying out foreground detection in an improved self-adaptation Gaussian mixture modeling method, the third step of recognizing a target block mass to obtain block mass information, the fourth step of carrying out real-time tracking on the target block mass, and the fifth step of carrying out Kalman filtering on the center of the target block mass to obtain a predicted value, comparing the predicted value with an actual value, and if the predicted value is larger than a threshold value, then behaviors are determined to be abnormal, and an emergent message is sent out. According to the method, privacy of a monitored object can be protected in a certain degree through the infrared camera, behavior monitoring is carried out through videos, the purpose of monitoring abnormal behaviors in a non-contact mode is achieved, meanwhile, the tracking algorithm used in the method is good in real-time performance, features of a tracked object are easy to obtain, quickness of the operational process is good, and the judgement standard is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of video images, and relates to a method for monitoring abnormal behaviors of elderly people living alone in a family environment. Background technique [0002] With the rapid development of economy and society, people's living standards and medical and health security have been greatly improved, and the fertility rate has remained at a low level. The age structure of my country's population has undergone major changes. According to the data of the sixth national census, the population aged 60 and above accounted for 13.26%, an increase of 2.93 percentage points compared with 2000, and the aging process of our country is gradually accelerating. With the continuous acceleration of my country's population aging process, the extension of life expectancy and the further decline of fertility rate, the phenomenon of "empty nest" is becoming more and more prominent, and the number of empty nest elderly is increasin...

Problems solved by technology

When the neural network is trained in this scheme, a large number of samples are required to obtain more accurate parameters. Due to the complexity and diversity of human behavior, the recognition results lack a certain accuracy guarantee.

At the same time, most of the existing solutions use ordinary cameras for direct monitoring, which lacks privacy protection for the monitored objects.
