Lower limb fatigue grade identification method and system based on gait information

The invention discloses a lower limb fatigue grade identification method and system based on gait information, and the method comprises the steps: dividing fatigue grades through a data collection module, and obtaining a gait information signal of the corresponding fatigue grade; performing gait segmentation on the gait information signal by using a data preprocessing module, and extracting statistical features from a gait sequence after gait segmentation; based on the statistical characteristics, loading an optimal fatigue state recognition model through a fatigue grade recognition module so as to perform fatigue grade recognition on the statistical characteristics; the data acquisition module is simple in design and low in cost, and the normal life of a wearer is not affected in the wearing process; and meanwhile, the real-time performance of fatigue recognition and the accuracy of fatigue grade recognition are improved. 本发明公开了一种基于步态信息的下肢疲劳等级识别方法及系统，其中，一种基于步态信息的下肢疲劳等级识别方法包括：通过数据采集模块划分疲劳等级，并获取相应疲劳等级的步态信息信号；利
