Embodiment 1

[0032] Embodiment 1 of the present invention provides a step size estimation method, such as figure 2 As shown, it specifically includes the following steps:

[0033] S201. When the step counting starts, for each preset time length, according to the motion acceleration of the human body detected by the acceleration sensor within the preset time length, determine the motion index of the human body within the preset time length, and the motion index may include the motion step frequency and / or exercise intensity.

[0034] further, Figure 3a-3b It is a statistical diagram of the numerical relationship between the movement index of the human body and the step length and height ratio of the human body. According to the statistical data of multiple human samples, there is a strong positive correlation between the human body's stride frequency and the human body's step-to-height ratio, and there is also a strong positive correlation between the human body's exercise intensity and...

Embodiment 2

[0065] Embodiment 2 of the present invention provides a method for estimating step length. In the method for estimating step length provided in Embodiment 2, a pedometer server may be provided for the pedometer, and the step server may provide the pedometer with human characteristic parameters. In this way, the user does not need to set it every time the pedometer is used. Every time the step length is estimated, the pedometer server can provide the human body characteristic parameters, and the information such as the movement distance and energy consumption of each exercise can be transmitted to the pedometer in real time. The pedometer server uses the pedometer server to store the exercise information of multiple exercises, saving the storage space of the pedometer, enabling users to easily query their own exercise conditions within a period of time, and modify the exercise plan according to the exercise conditions within a period of time Wait.

Abstract

Embodiments of the invention provide a step length estimation method, a pedometer and a step counting system. According to the present invention, when step counting is started, based on each preset duration, according to the human body motion acceleration detected by an acceleration sensor within the preset duration, the motion indexes of the human body within the preset duration are determined, wherein the motion indexes comprise motion step frequency and/or motion intensity; based on the numerical relationship between the pre-statistical motion indexes and the human body step length/height ratio, and the motion indexes, the step length/height ratio is determined; and according to the human body height, the motion step length within the preset duration is estimated; and with the step length estimation method, the pedometer and the step counting system, the problem that the calculation is not accurate when the pedometer uses the step length output by the user to calculate the motion distance is solved in the prior art. The present invention relates to the technical field of computers.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a step length estimation method, a pedometer and a pedometer system. Background technique [0002] In the prior art, a pedometer can be used to estimate information such as the number of steps a human body takes during exercise, the exercise distance, and the energy consumed by the human body through the exercise distance, so that users can have an in-depth understanding of their own activities. Among them, the number of movement steps can be counted by the sensor on the pedometer, and the estimation of the movement distance is usually obtained by multiplying the movement steps by the movement step length of the human body, but the estimation of the movement step length has always been a difficult problem, because According to the difference of human body structure, the step length during exercise is quite different. Even for the same person, the movement step length also has g...
