Problems solved by technology

The calculation of the swing amplitude in the three-dimensional interval is extremely complicated, and it is necessary to refer to the coordinate value changes of the three coordinate axes of the three-dimensional coordinate system in the three-dimensional interval to calculate the result of the number of steps
[0004] At present, the algorithm for calculating the number of steps taken by the wearer wearing the smart wearable device is too complicated, which needs to consume a lot of system resources, consumes a lot of power, and leads to poor user experience.

Abstract

The embodiment of the invention discloses a step counting method and device. The step counting device is fixed on a wearer and can acquire the current accelerated speed as the initial acceleration after the step counting device is started, wherein the accelerated speed is the displacement acceleration of the step counting device in a Z-axis direction of the coordinated system; the step counting device records the difference value of the current accelerated speed and the initial acceleration, when the difference value is more than the first preset difference value, the current accelerated speed is determined to be in a first wave band; when the difference value is less than the first preset difference value, the current accelerated speed is determined to be in a second wave band; when the current accelerated speed of the step counting device is alternatively in the first wave band and the second wave band, one step number is added when the alternating operation occurs one time, and therefore, the change of the accelerated speed of the step counting device in the Z-axis direction is only referred during step counting, a algorithm is simple, the calculating amount is low, occupied system resources are few, the power consumption is low and the user experience degree is high.

Description

technical field [0001] The invention relates to the field of computers, in particular to a step counting method and device. Background technique [0002] At present, the functions that can be realized by smart wearable devices are becoming more and more comprehensive, and many of the functions realized are closely related to the wearer who wears the smart wearable device. For example, the number of steps taken by the wearer during exercise is counted. [0003] Smart wearable devices generally obtain their own swing range in a three-dimensional interval through sensors, and then calculate the number of steps taken. The calculation of the swing amplitude in the three-dimensional interval is extremely complicated, and it is necessary to refer to the coordinate value changes of the three coordinate axes of the three-dimensional coordinate system in the three-dimensional interval to calculate the result of the number of steps. [0004] Currently, the smart wearable device calcu...
