Description

[0002] A flat foot corrective insole is an insole specifically designed to correct or relieve the symptoms of flat feet. Flat feet refer to the collapse or absence of the arch of the foot, resulting in the sole of the foot contacting the ground completely or almost completely, which may cause foot pain, abnormal gait, knee and lumbar problems.

[0110] Label and classify the abnormal features (such as abnormal gait, degree of arch collapse, signs of fatigue, etc.) of the diversified data, and then select a convolutional neural network (to process the plantar pressure heat map and identify abnormal gait) and LSTM (to analyze the gait cycle and arch change trend) for model training. During the training process, introduce historical flat foot correction experience through transfer learning to obtain an identification model.

[0111] 5.2 Correction Suggestion Unit
