Embodiment 1

[0027] figure 1 It is a flow chart of Embodiment 1 of a positioning method provided by the present invention. Such as figure 1 As shown, method embodiment one includes:

[0028] 101. Use at least one sensor on the sole of the foot or the sole of the shoe to obtain the ground surface feature of the position where the body is located.

[0029] Specifically, the at least one sensor can be arranged on the sole of the foot or the sole of the shoe in various ways, for example, it can be arranged on the sole of the shoe, the insole or the sock.

[0030] Specifically, the surface features include at least one of the following: texture, texture, flatness, inclination, and steps. Among them, the texture can include but not limited to: hard, soft, etc., for example, the cement floor is hard, and the carpet and grass are soft; texture refers to the linear lines on the surface, such as patterns on the ground, etc.; Degree can be used to distinguish different flatness of the ground, inc...

Abstract

The invention provides a positioning method, apparatus, system and device. The method comprises the steps of acquiring a surface feature of a position where a body is located through at least one sensor arranged at a foot sole or a shoe sole; determining the position where the body is located according to the surface feature. The invention provides a new positioning scheme; furthermore, by utilizing the surface feature for positioning, the method can not be affected by environmental factors (such as electromagnetism or sound noise and the like), and the positioning result is very reliable.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of positioning, and in particular, to a positioning method, device, system, and device. Background technique [0002] Positioning technology has been widely used. For example, the Global Positioning System (GPS) technology is very mature and widely used in navigation and other fields. However, the positioning accuracy of GPS is low, and the signal is weak in the indoor environment, so it is not suitable for indoor applications. Therefore, in recent years, many positioning methods, devices and systems suitable for indoor environments and different from GPS have been produced. For example, positioning can be achieved by using the fading and transmission delay characteristics of electromagnetic waves (such as Bluetooth, WIFI, etc.), sound, visible light and other signals transmitted in the air; it is also possible to achieve positioning according to the different magnetic field distri...
