The invention provides a human activity fine-grained identification method based on a
human body RFID skeleton, and belongs to the field of
deep learning. According to the method, an advanced identification method and existing problems are considered, firstly, 16 RFID flexible tags are arranged at main joints of a
human body by using an RFID technology and distribution of a
human skeleton, a new human activity
data set is acquired by reading the tags, the
data set is an activity
data set with most human activity types in the HA R field of bound RFID so far, and the data set is a new human activity data set with most human activity types in the HA R field of bound RFID. The problems that at present, the HA R based on the binding type RFID mainly utilizes
human body trunk movement information, four-limb movement information related to human activities is lacked, human activity characteristics cannot be effectively captured, and the types and the number of human activities are small are solved. Then, based on the sampling data, a space-time skeleton diagram of human body activities is designed, and the problem that at present, HAR based on binding type RFID cannot utilize a graphic
interaction network to classify graphs is solved. And finally, designing a space-time skeleton diagram convolutional network for human activity identification, and classifying the space-time skeleton diagram to realize human activity identification, thereby solving the problems that the HAR based on binding type RFID uses the traditional
machine learning as an identification method at present, the HAR is limited in modeling capability for complex activities and low in accuracy. Experiments show that the method is a simple and feasible fine-grained human activity identification method.
