Plantar pressure analysis method

Abstract

The invention relates to a plantar pressure analysis method. The method comprises the following steps of: obtaining plantar pressure data and preprocessing the plantar pressure data to obtain plantar pressure indexes (a plantar pressure maximum value, a plantar pressure average value, a plantar pressure variance, a plantar pressure standard deviation, a pressure intensity and the like); further processing a plantar pressure round edge in the preprocessed plantar pressure data to obtain a smooth plantar image satisfying a predetermined requirement; and partitioning the smooth plantar pressure image to obtain foot indexes (a foot contact area, a foot gravity center, an arch length, a foot length and a foot width), and analyzing a standing posture, strephenopodia and strephexopodia indexes and arch indexes of a testee. Through the plantar pressure analysis method, the plantar pressure distribution condition can be comprehensively analyzed, the further analysis for the plantar pressure data is realized, the analysis result is optimized, the analysis error is decreased and various plantar pressure indexes are obtained correctly.

Description

technical field [0001] The invention relates to the field of measurement data analysis and processing, in particular to a method for analyzing plantar pressure. Background technique [0002] The human foot is a complex result of 26 bones, 33 joints and 126 ligaments, muscles and nerves communicating in layers like a network. Its basic functions are mainly to support the body weight, buffer and absorb impact; generate forward thrust and help adjust and maintain the balance of the human body. When the human body is standing still or walking dynamically, under the action of its own gravity, the sole of the foot is subjected to a reaction force from the ground in the vertical direction, which is the plantar pressure. The foot of the human body is a relatively small part compared to the whole body, but every time the human body walks, the pressure on the sole of the foot is huge, which probably exceeds 50% of the body weight. As far as people's daily life is concerned, the aver...

Problems solved by technology

[0003] At present, the existing precise measuring equipment is generally limited to professional institutions due to the characteristics of many measuring points, complicated control and high price. On the other hand, the existing simple measuring device has the characteristics of small measuring points and inaccurate positioning Cannot be used as a basis for professional analysis

Furthermore, since the subject’s standing posture is different each time, the obtained pressure index will have some differences; the subject’s standing position may be different each time, and the obtained analysis results will have some differences; the part of the sole that does not touch the pressure plate has no Pressure value, therefore can not get a very complete foot shape
