Abstract

The invention is suitable for the technical field of wireless positioning, and provides a distance measurement positioning method and device, and the method comprises the steps of obtaining a group ofdistance data between a label and each of at least three base stations; establishing a corresponding three-dimensional coordinate mathematical model according to the three-dimensional coordinate dataof each base station and the corresponding preprocessed group of distance data, so as to generate a corresponding number of three-dimensional coordinate mathematical models according to the number ofthe base stations; carrying out linear conversion of a nonlinear equation set on the plurality of generated three-dimensional coordinate mathematical models; and iteratively calculating a three-dimensional positioning value and an iterative error value of the label according to the linear equation set and a preset iterative initial value, wherein the preset iterative initial value is an initial coordinate value of the label. By processing the distance data and optimizing the distance algorithm, compared with a traditional positioning calculation mode, the method of the invention has higher positioning precision.

Description

technical field [0001] The invention belongs to the technical field of wireless positioning, and in particular relates to a method and device for ranging and positioning, terminal equipment, and a computer-readable storage medium. Background technique [0002] Ultra Wideband (UWB) is a wireless communication technology that transmits data at high speed within a short distance with extremely low power. UWB has strong anti-interference performance, high transmission rate, extremely wide bandwidth, low power consumption, and low transmission power. And many other advantages, mainly used in indoor communication, home network, location determination, radar detection and other fields. The system capacity is large and the transmission power is very small, and its electromagnetic wave radiation will have little impact on the human body, and its application is wide. [0003] In recent years, its sub-nanosecond ultra-narrow pulse has been used for short-distance precise indoor positi...
