Walking movement classification method based on triaxial acceleration transducer signals

Abstract

The invention relates to a walking movement classification method based on triaxial acceleration transducer signals, which comprises the following steps: fixing a triaxial acceleration transducer on the upper part of the ankle of a testee, connecting the triaxial acceleration transducer with a computer, setting an initial value, and acquiring the variation conditions of different accelerations during the movement; calling a one-step detection subprogram; judging whether the one-step detection is successful; calling a downstairs movement state detection subprogram; judging whether the testee is in the downstairs movement state; calling a voting algorithm subprogram; judging whether the testee is in the upstairs movement state; judging whether the testee is in the forward movement state; setting the movement state as the forward movement state; setting the movement state as the upstairs movement state; setting the movement state as the backward movement state; setting the movement stateas the downstairs movement state; judging whether the current acceleration value exceeds the preset value; setting the movement state as the stationary state; setting the movement state as the running state; and ending. The invention provides an effective solution for individual navigation systems, M-health systems to evaluate the position of walkers in some regions not covered by GPS signals.

Description

technical field [0001] The invention relates to a walking motion classification method. In particular, it relates to a method of acquiring acceleration changes during walking, and proposing a walking motion classification method based on 3-axis acceleration sensor signals to distinguish walking motion states according to the obtained data signals. Background technique [0002] With the rapid development of today's computer technology, various computer technologies are used in different fields. With the popularization of handheld computers and the development of sensor technology, especially the development of sensor miniaturization technology, the use of motion detection systems is easier to carry, and the acquisition and processing of motion information is more convenient. , but also promote the development of motion classification technology. The so-called motion classification algorithm refers to a motion classification method that divides motion into different motion st...
