Embodiment 1

[0068] see figure 1 , a video monitoring abnormal behavior system for smart home elderly care in this embodiment mainly includes a monitoring camera 100 , a video processing node 200 and a communication center 300 . The surveillance camera 100 serves as a data source of the video surveillance system, and transmits the captured indoor scenes to the video processing node 200 in real time through a wireless network.

[0069] see figure 2 , each surveillance camera 100 in this embodiment includes two high-definition lens 101 and lens 102 . Among them, lens 101 uses a fixed-focus lens as an indoor scene monitor to monitor the activities of the elderly indoors in real time; lens 102 uses an automatic zoom lens as an auxiliary monitoring of facial expressions. Capture the outline of the face, then change the focal length to clarify the facial expression, and then transmit the data of the lens 102 to the video processing node 200 for abnormal expression recognition as an auxiliary ...

Abstract

The invention discloses a smart home old age support video monitoring abnormal behavior system and method, and belongs to the technical field of mode identification and computer vision. The monitoring system provided by the invention comprises a double-lens monitoring camera, a video processing node and a communication center. According to the system, the indoor activity condition can be monitored in real time through the double-lens monitoring camera; an abnormal behavior is processed through the video processing node; whether there is an abnormal behavior activity or not is detected by taking face expressions as auxiliary identification; and abnormal behavior alarm information is sent to a user through the communication center. According to the system and the method, the body activity state can be monitored in real time, and alarm is generated when there is the abnormal condition. The system and the method have the advantages of wide application range, high security and stable and reliable identification.

Description

technical field [0001] The invention relates to the field of pattern recognition, computer vision, automation technology and embedded technology, and more specifically, to a system and method for video monitoring abnormal behaviors of smart home elderly care. Background technique [0002] According to the latest statistics from the civil affairs department, the problem of population aging in my country is becoming more and more serious, with an elderly population as high as 162 million. Since 2009, my country has entered a rapid development stage of aging, and the number of elderly people will reach 248 million by 2020, with an average of one elderly person in every three or four people. Excessive aging speed will cause a series of social problems. The imperfect security system for the elderly and the lagging service development all reflect that my country has obvious deficiencies in population aging. [0003] With the introduction of the concept of the Internet of Things i...
