Embodiment Construction

[0059] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0060] When the human body is walking and running in a stable state, the whole human body moves at a uniform speed in the horizontal direction, so the main acceleration is the acceleration in the up and down direction, and there is not much side acceleration and front and rear acceleration. Such as figure 1 As shown, in the process of walking or running, when the right foot moves from the position of B1 to B2, the left foot remains at the position of C without moving, while the hip joint rises from the position of A1 to the position of A2 and then descends to A3 s position. If the acceleration sensor is placed in the pocket of the human body or on the waist, the acceleration in the up and down direction of the human body can be detected, and by analyzing the fluctuation of the acceleration in the up and down direction, the steps of the person c...

Abstract

The invention provides a step counting method which comprises the steps: accelerations in all directions are obtained; a composite acceleration is calculated; a judgment of whether run or walk is made according to the amplitude of the composite acceleration. In the step counting method, an acceleration testing method adopted can distinguish the running of the human body from the walking of the human body, and a real walking from other disturbance. Besides, the invention also provides a step counting device and methods for rectifying stride and estimating moving distance.

Description

【Technical field】 [0001] The invention relates to an electronic device, in particular to a step counting method, a stride correction method, a distance measuring method and a step counting device. 【Background technique】 [0002] With the development of electronic technology, various electronic devices are widely used in people's work and life. Among them, the pedometer is used to count the number of steps taken by the human body for walking or running, which is used as a basis for people to evaluate the amount of exercise. [0003] The pedometer generally includes an acceleration sensor and a detection circuit connected to the acceleration sensor. The acceleration sensor generates a signal in response to the periodic acceleration fluctuation of the human body during walking or running, and the detection circuit counts the number of walking or running steps according to the signal generated by the acceleration sensor. [0004] However, traditional pedometers can only count ...
