Abstract

The invention belongs to the technical field of image processing, and specifically provides a posture recognition method and system based on an infrared sensor. According to the scheme, an indoor scene is imaged based on the infrared sensor, human body target detection and posture recognition are carried out through the rear-end information processing module. Once an abnormal posture is detected,for example, falling down, an abnormal alarm signal is immediately output through a network, and a recognized abnormal image picture is output to the alarm terminal. The infrared sensor captures humanbody temperature information, so that the problem of human body privacy leakage does not exist, and the system can work all day long. On one hand, a room can be monitored by adopting a single wide-angle infrared sensor, the imaging distance is increased, and the practicability is enhanced. On the other hand, the target detection network and the classification network are adopted, the human body only needs to be within the image range, any position can be automatically detected, then posture classification is conducted on the human body, and practicability is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a posture recognition method and system based on an infrared sensor. Background technique [0002] At present, the aging trend of the global population is increasing, and incidents of injuries caused by elderly people living alone due to falling indoors and not being detected in time occur from time to time. At present, there are various products for fall detection of the elderly, but they can be mainly divided into two categories: [0003] One is based on wearable devices equipped with acceleration sensors, such as smart bracelets, mobile phones, etc., according to the built-in acceleration sensors of the instruments, the real-time attitude information of the wearer is predicted; the other is based on video intelligent monitoring products, which do not need to be actively worn Equipment and instruments are mainly composed of one or more sensors such as visi...
