Embodiment Construction

[0029] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0030] Application overview

[0031] As mentioned above, since the environment where wireless positioning technology is applied may have a complex geographical structure, in this case, it is difficult for wireless signal transmission to propagate in line of sight (LOS: line of sight), and it is always transmitted in a non-line of sight (LOS: line of sight) through reflection and diffraction. (NLOS: not line of sight)), which will bring positioning errors up to hundreds of meters, and become the basic source of positioning errors. Therefore, in this positioni...

Abstract

The invention relates to an object positioning method and device based on positioning chip internal parameters and electronic equipment. The object positioning method includes the steps that internalparameter information of a positioning chip of an object to be positioned is acquired; at least one of a kurtosis parameter, a skewness parameter and a power ratio parameter is calculated based on theinternal parameter information, and the kurtosis parameter and the skewness parameter are calculated based on a channel impulse response; a signal propagation mode of the object to be positioned is determined based on at least one of the kurtosis parameter, the skewness parameter and the power ratio parameter; and the object to be positioned is positioned based on the signal propagation mode of the object to be positioned. In this way, at least one of the kurtosis parameter, the skewness parameter and the power ratio parameter for determining the signal propagation mode can be calculated by the internal parameters of the positioning chip of the object to be positioned, and thus the positioning accuracy is improved.

Description

technical field [0001] The present application generally relates to the technical field of positioning, and more specifically, relates to an object positioning method, device and electronic equipment based on internal parameters of a positioning chip. Background technique [0002] With the development of positioning technology, more and more ways of positioning through wireless signals have emerged. For example, in the field of indoor positioning, common positioning methods include WIFI positioning, Bluetooth positioning, infrared positioning, RFID positioning, ultrasonic positioning, ZigBee positioning and ultra-wideband (UWB) positioning. [0003] These wireless positioning technologies mainly measure the target node through the distance or angle from the target node to the receiving node, and then calculate the position information. Wireless ranging technology can be divided into ranging technology based on received signal strength (RSSI), ranging technology based on sig...
