Infrared-panorama-pick-up-head-based abnormal behavior identification method of elderly people living alone

Abstract

The invention, which belongs to the technical field of the video image, discloses an infrared-panorama-pick-up-head-based abnormal behavior identification method of elderly people living alone. The method comprises: step one, an infrared panorama pick-up head is used for carrying out infrared shooting, thereby obtaining a video image signal; step two, an infrared panoramic picture is unfolded by using a fast approximate unfolding method; step three, an indoor grid semantic map in a home environment is constructed; step four, on the basis of an improved hybrid Gaussian model algorithm, modeling of a human body target is carried out, a target block mass is identifier, block mass information is obtained, the target block mass is tracked in real time, and a human body track feature is obtained; step five, a human body moving track is extracted by using a hybrid Gaussian clustering method; step six, the human body track is segmented; and step seven, a convolutional neural network is trained by using the track after human body motion segmentation in the home environment as a training sample, feature extraction is carried out on a human body behavior track in the home environment, and classification is carried out by using evidence reasoning; and if an abnormal situation occurs, alarming is carried out.

Description

technical field [0001] The invention belongs to the technical field of video images, and relates to a method for identifying abnormal behaviors of elderly people living alone based on an infrared panoramic camera. 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 continues to remain low. The aging of my country's society is grim. In 2013, my country's elderly population over 60 years old exceeded 200 million. It will exceed 300 million, and will exceed 400 million in 2040. At that time, the elderly over 80 years old will reach 100 million. Aging will affect China's economy and society for a long time. Due to the implementation of the family planning policy, the traditional nuclear family structure in my country has changed, and the family size has become smaller and smaller, breaking the traditional family model of three or even four gene...

Problems solved by technology

However, most of the existing solutions use ordinary cameras for direct monitoring, and it is difficult to meet the needs of human behavior recognition in terms of imaging range and resolution, and it is difficult to protect the privacy of the monitored objects.

The limited visual range of ordinary cameras limits the acquisition of information. If the visual range can be expanded, the problem of information acquisition will be easily solved
