Abstract

The invention belongs to the technical field of image processing, and specifically provides a gesture recognition method and system based on an infrared sensor. The scheme is based on an infrared sensor to image an indoor scene, and uses a back-end information processing module to detect human objects and recognize gestures. Once an abnormal posture such as a fall is detected, an abnormal alarm signal will be output through the network immediately, and the identified abnormal image screen will be output to the alarm terminal. Since the infrared sensor captures the temperature information of the human body, there is no problem of leaking the privacy of the human body, and it can work all day. On the one hand, a single wide-angle infrared sensor can be used to monitor a room, which improves the imaging distance and enhances the practicability; on the other hand, the target detection network + classification network is used, and any position can be automatically detected as long as the human body is within the image range , and then perform pose classification on it, the 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...
