Embodiment Construction

[0086] The terms used in the embodiments of the present invention are only used to explain specific examples of the present invention, and are not intended to limit the present invention.

[0087] figure 1 It is a schematic diagram of an application scenario involved in an embodiment of the present invention. Such as figure 1 As shown, the user is running or walking while carrying the wearable device 10 and the smart phone 20 . in:

[0088] The smart phone 20 is configured with a distance monitoring component, which can directly measure the user's actual movement distance. In a specific implementation, the distance monitoring component can be a GPS module, which can directly measure the user's actual movement distance through a satellite positioning system, and can be mainly used in an outdoor open environment. In some embodiments, the distance monitoring element can also be an RF (Radio Frequency, Chinese: radio frequency) positioning module, such as a Wi-Fi positioning m...

Abstract

This paper discloses a stride calibration method. The method includes: the first device detects that the user is walking or running, and collects the number of motion steps of the user, and judges whether the user's stride in the preset database needs to be calibrated, and if calibration is required, the second device The device requests to obtain the user's actual movement distance; the user's stride in the preset database is used to provide the first device to calculate the user's movement distance; the first device calculates the user's movement distance according to the user's Calculate the actual stride of the user based on the actual distance of movement and the number of steps of the user, and use the calculated actual stride to update the stride of the user in the preset database. The above solution can realize stride estimation and calibration for the first device that is not configured with a distance monitoring element, thereby improving the accuracy of the first device in calculating the user's movement distance.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a stride calibration method, related equipment and a system. Background technique [0002] In recent years, consumer electronic products, such as mobile devices (including smartphones, tablet computers, etc.) are equipped with various types of motion sensors, such as accelerometers, gyroscopes, and magnetometers, which can identify whether the user is walking or Running status, and can count the user's exercise steps, exercise posture, calorie consumption and other exercise indicators to provide users with better application functions and experience. [0003] Currently, the mobile device configured with the motion sensor may be configured with a distance monitoring element (such as a GPS module), or may not be configured with a distance monitoring element. A mobile device equipped with a distance monitoring component, such as a smart phone, can accurately measur...
