Embodiment

[0026] Embodiment: This embodiment is a method for recognizing foot movement based on a three-axis acceleration sensor. The three-axis acceleration sensor is arranged in the shoe with the positive direction of the X axis facing the front of the shoe body, and the positive direction of the Y axis facing the left or right side of the shoe body , The positive direction of the Z axis is straight up, such as figure 1 As shown, including the following steps:

[0027] S1: The microprocessor reads the detection data output by the three-axis acceleration sensor, and selects the corresponding data for processing according to the human motion state. The human motion state is initially set to the walking state. When the human motion state is walking or jogging, only select XYZ three-axis combined acceleration data are processed. When the human body motion state is fast running, only the X-axis acceleration data is selected for processing;

[0028] S2: The microprocessor draws an acceleration ...

Abstract

The invention discloses a footstep movement identification method based on a triaxial acceleration sensor. The method comprises the following steps: S1, reading detection data output from the triaxial acceleration sensor by a microprocessor, and processing corresponding data selected according to a body kinematic state; S2, drawing an acceleration change curve according to the selected data by the microprocessor, detecting the peak of wave in the acceleration change curve and determining the falling time of the foot according to the peak of the wave; S3, calculating the falling posture of the foot by the microprocessor; S4, judging the current body kinematic state by the microprocessor and setting. According to the method of the invention, the falling posture of the foot of people during movement can be identified, so that the convenience is brought to a user to know the self-postures of walking and running.

Description

Technical field [0001] The present invention relates to the technical field of motion recognition, in particular to a method for recognizing foot movement based on a three-axis acceleration sensor. Background technique [0002] Many modern people pay much attention to their daily exercise. As a monitoring method for effective recording and monitoring of exercise, step counting is widely used in smart running shoes. The existing smart running shoes are equipped with a three-axis acceleration sensor, but they can only simply count steps and cannot recognize the landing posture of the foot during exercise, which is not conducive for users to understand their walking or running posture. Summary of the invention [0003] The purpose of the present invention is to overcome the technical problem that the three-axis acceleration sensor installed in the current smart running shoes can only simply count the steps, and cannot recognize the landing posture of the foot when the person is movin...
