Human body key point detection method and system based on Wi-Fi signal

Abstract

The invention discloses a human body key point detection method and system based on a Wi-Fi signal. The method comprises the following steps: recording CSI data and CSI timestamps in signal coverage ranges of a Wi-Fi signal transmitting end and a Wi-Fi signal receiving end; and recording video data and UNIX timestamps; performing cross-modal indirect labeling on the CSI data by using the collected video data; taking the marked CSI data as training data, inputting the training data into a Wi-Fi Transformer model for training, and storing the training data after the Wi-Fi Transformer model converges; and inputting the Wi-Fi data to be detected into the trained Wi-Fi Transformer model, and outputting the key point data of the human body. According to the method and system, the Wi-Fi Transformer model is adopted to detect the key points of the human body, and the method is simple, rapid and accurate; sensitive privacy such as human faces cannot be exposed; therefore, the method and system can be used in the fields of daily life and health medical treatment.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence of the Internet of Things, and in particular relates to a method and system for detecting key points of a human body based on Wi-Fi signals. Background technique [0002] Human body key point detection can be used for tasks such as action recognition, human-computer interaction, and health care in smart homes. The existing human body key point detection technology is mainly based on the camera, which is mostly used in application scenarios such as virtual reality games. In family scenes outside of games, users have a strong awareness and requirements for privacy protection, and camera-based technology is no longer suitable. [0003] In addition, camera-based technology will bring users great privacy concerns, such as fall detection tasks for the elderly in the bath or bedroom, and is even more unsuitable. Therefore, there is a great social demand for privacy-friendly human keypoi...
