Abstract

The invention provides a step-counting preprocessing method, a device and a terminal. The method includes the steps of: S101, acquiring acceleration original data; S101, subjecting the acceleration original data to unit conversion to obtain an acceleration value; S102, conducting real-time dynamic threshold calculation according to the acceleration value; S103, judging whether the acceleration value conforms to a real-time dynamic threshold; and S104, carrying out step-counting processing according to the judgment result of the above steps. The invention employs a dynamic threshold method to increase the step-counting precision, thus reducing the influence of arm swing during walking on the step-counting precision. The method mainly involves the application of acceleration model root-finding, acceleration variance, walking frequency, signal energy and other related concepts, and can effectively improve the step-counting precision under the conditions of a small walking range and abnormal gait.

Description

technical field [0001] The present invention relates to the field of step counting, in particular to a step counting preprocessing method, device and terminal. Background technique [0002] As a device that can record the number of steps taken by the wearer, the pedometer can be worn on the waist, wrist, etc. Through the pedometer, not only the number of steps taken by the wearer can be calculated, but also the energy consumed and the distance traveled by the wearer can be calculated. Pedometers are also used in inertial navigation systems to determine the wearer's walking profile. Among them, the pedometer mainly uses the original signal of the accelerometer, and after some processing, it realizes the step counting function through the step counting algorithm. Since the walking process of the human body is a periodic process, the acceleration of the human body perpendicular to the ground will periodically change from small to large when walking. The three-dimensional inst...
