摘要： Technical solutions are described for step counting, performed by: calibrating (100) a step counting frequency and/or an effective value of step counting pace of a three-axis acceleration sensor according to acquired step counting data of a preset number of steps; and performing (101) step counting according to the calibrated step counting frequency and/or the calibrated effective value of step counting pace of the three-axis acceleration sensor obtained from the calibration. By calibrating the step counting frequency and/or the effective value of step counting pace of the three-axis acceleration sensor, error in the step counting caused by different walking paces of a user and different step counting frequencies of the three-axis acceleration sensors are avoided, improving accuracy of step counting. Also, the calibration improves the accuracy by handling ineffective step counting in the step counting data.
