Abstract
A stride length calibration method includes detecting, by a first device, that a user is walking or running, and collecting a quantity of movement steps of the user. The method further includes determining whether a stride length of the user in a preset database needs to be calibrated. The method further includes requesting to obtain, from a second device, an actual movement distance of the user when calibration is needed. The stride length of the user in the preset database is provided to the first device to calculate a movement distance of the user. The method further includes calculating, by the first device, an actual stride length of the user based on the actual movement distance of the user and the quantity of movement steps of the user. The method further includes updating the stride length of the user in the preset database by using the actual stride length obtained through calculation.
