Intelligent monitoring method and system for environment-assisted life

Abstract

The invention relates to an intelligent monitoring method and system for environment-assisted life. The method comprises the steps that: a TOF camera collects first three-dimensional point cloud dataof a scene; the TOF camera sends the first three-dimensional point cloud data to a server; the server extracts first point cloud depth data of the first three-dimensional point cloud data; the serverperforms de-noising processing on the first point cloud depth data to generate second point cloud depth data; the server performs human body edge contour extraction on the second point cloud depth data to generate third point cloud depth data; the server recovers the third point cloud depth data into second three-dimensional point cloud data; the server calculates human body three-dimensional center coordinates according to the second three-dimensional point cloud data; the server extracts a human body center height value perpendicular to the ground direction in the human body three-dimensional center coordinates; the server compares the human body center height value with a first threshold value; and if the human body center height value is smaller than or equal to the first threshold value, the server sends alarm information to the terminal.

Description

technical field [0001] The invention relates to the fields of three-dimensional data processing and automatic control, in particular to an intelligent monitoring method and system for environment-assisted living. Background technique [0002] With the continuous improvement of medical conditions, the average life expectancy of human beings is continuously extending, and the phenomenon of aging society is increasing day by day. For the elderly with few children or widows, they cannot receive comprehensive daily care, and the elderly cannot receive timely assistance when they fall. It will often have serious consequences and bring a heavy burden to yourself and your family. Especially in our country, under the influence of traditional concepts, few elderly people are willing to enter nursing homes for the elderly. The society is constantly strengthening the health care of the elderly and disease prevention. In recent years, the concept of environmental assisted living has been...

However, the vision system combined with a monocular camera and multiple cameras is a passive vision system. The passive vision system is easily affected by many factors, including the existence of shadows, camouflage effects, brightness fluctuations, surface features and occlusion, etc.
