Embodiment 1
[0039] Such as figure 1 As shown, the implementation method of this embodiment includes the following steps:
[0040] Step 1. Training data collection. The gait information of pedestrian walking and running is obtained as the original training data by using the training stage data acquisition module installed on the pedestrian's foot.
[0041] The data acquisition module in the training phase includes: an accelerometer and a gyroscope. The foot movement information includes the triaxial acceleration and triaxial angular velocity signals generated by the pedestrian's foot during movement. Therefore, there are six sets of raw training data for each class of gait. The original training data for each type of gait contains only one kind of gait, that is, pure walking or pure running data.
[0042] Step 2, training data processing. Use the data processing module in the training phase to process the training data, specifically:
[0043]2.1) Sampling point selection: Extract the...
