Problems solved by technology

The setting of the threshold used in this method is affected by many factors, such as human motion characteristics and accelerometers, so this method is only suitable for scenes where the user moves at a uniform speed, and it is easy for scenes with non-uniform motion such as stop and go. Misjudgment occurs, resulting in a decrease in step counting accuracy

Abstract

The invention provides a step counting method and a terminal device. The step counting method comprises the steps: acquiring an acceleration magnitude of the terminal device in real time; determining maximal values and minimal values in the acceleration magnitude; transforming the frequency domain of the acceleration magnitude between each two adjacent maximal values and two adjacent minimal values when the difference between the adjacent maximal value and minimal value is greater than an acceleration threshold value, and acquiring a walking frequency in the time corresponding to the two adjacent maximal values or the two adjacent minimal values; determining that a user carrying the terminal device moves a step in the corresponding time if the walking frequency in the corresponding time is greater than a preset frequency threshold value, and adding 1 to the step number. By adopting the technical scheme, the probability in misjudging when the step is counted can be reduced, and the step counting precision is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of analysis and measurement control, in particular to a step counting method and terminal equipment. 【Background technique】 [0002] With the development of science and technology and the popularization of inertial sensors of Micro-Electro-Mechanical System (MEMS), more and more electronic devices such as pedometers, mobile phones, and smart watches have gyroscopes and accelerometers, which can help User statistics collect sports information and analyze the user's running status. [0003] Most of the existing step counting methods collect the user's acceleration value through the accelerometer, find the peak and trough of the acceleration, compare the difference between the adjacent peaks and troughs with the preset threshold, and judge whether the user has moved according to the comparison result. The setting of the threshold used in this method is affected by many factors, such as human motion character...
