Abstract

The embodiment of the invention provides a step counting device and a step counting method, which can reduce step counting errors. The device comprises an accelerometer used for obtaining sampling values of accelerations of the step counting device along three coordinate axes of a carrier coordinate system, a gyroscope for obtaining sampling values of angular velocities of the step counting devicealong the three coordinate axes of the carrier coordinate system, and a processor for determining a pitch angle and a roll angle of the step counting device relative to an earth reference plane according to the sampling values of the accelerations and the sampling values of the angular velocities, and determining whether a motion posture of a human arm conforms to a preset motion posture according to the roll angle, wherein the processor is also used for counting steps when the pitch angle meets preset characteristics and is within a preset pitch angle range, and the motion posture of the human arm conforms to the preset motion posture.

Description

technical field [0001] The present application relates to the field of terminal equipment, and more specifically, to a step counting device and a step counting method. Background technique [0002] At present, the design idea of ​​a general-purpose pedometer device is to use a 3-axis accelerometer to measure the acceleration signal when pedestrians are walking, and then realize the pedometer function by identifying the standing period and stepping period of pedestrians walking. [0003] figure 1 A schematic diagram showing the movement of the legs when the human body takes one step, figure 2 It represents the change curve of the acceleration of the human body in the 3 axes (X axis, Y axis and Z axis) during walking. From figure 2 It can be seen that during the walking process, the acceleration rate in the horizontal direction (X-axis and Y-axis) is not large, and the acceleration in the vertical direction (Z-axis) changes periodically. The pedometer function can be rea...
