Method for measuring plantar pressure

Abstract

The invention discloses a method for measuring plantar pressure. The method mainly aims at reducing cost for accurate monitoring of plantar pressure information. A plantar pressure measurement device with lots of sensing points is first utilized for measuring the plantar pressure information; a model is established according to the information and a modeling method put forwards in the method and plantar pressure models; the model can present differences between different persons; finally, a plantar pressure measurement device with few sensing points is used for monitoring the plantar pressure information of a measurer; the plantar pressure information of various position points on the planta pedis is obtained through model backstepping reduction, and therefore complete and accurate plantar pressure information can be obtained through the simple devices. A layout of sensor arrays at different intervals is used for the optimized measurement device with lots of sensing points, and the optimized measurement device with few sensing points is obtained through embeddable structures of sensor units. Two kinds of models are used as the plantar pressure models and include a neural network model and an interpolation model relevant to distance.

Description

technical field [0001] The patent of the invention belongs to the field of plantar pressure measurement, and specifically relates to a method for improving the measurement accuracy and measurement range of a portable plantar pressure device through a plantar pressure model. Background technique [0002] The measurement of plantar pressure plays an important role in the diagnosis of foot and leg diseases, diabetes and other diseases, the design of shoes, identification of identity, intelligent control and other fields. However, due to the large number of measurement points, complex control, and high hardware requirements, the existing accurate measurement equipment is expensive, and is generally limited to professional institutions. On the other hand, simple measurement devices, even portable plantar pressure measurement equipment, Due to the small number of measurement points and inaccurate positioning, it cannot be used as a basis for professional analysis. This patent mod...
