Flexible sensor-based human body sitting posture recognition method and human body sitting posture recognition system

The invention discloses a flexible sensor-based human body sitting posture recognition method. According to the invention, firstly, the bending data of the back of a user are collected, and the bending data are preprocessed and extracted. Secondly, feature vectors are recognized by utilizing a well trained error back propagation type artificial neural network, and then a recognition result is obtained. Thirdly, the recognition result is transmitted to the intelligent terminal of a user. According to a flexible sensor-based human body sitting posture recognition system provided in the invention, the bending data of the back of the user are detected by a flexible sensor. Meanwhile, the processed bending data are recognized by utilizing a classification and recognition unit provided with theerror back propagation type artificial neural network. In this way, a final recognition result can be obtained. Moreover, the recognition result is transmitted to the intelligent terminal of the userthrough a wireless communi
