UWB positioning method, terminal and computer readable storage medium

Abstract

The invention provides a UWB positioning method, a terminal and a computer readable storage medium, the UWB positioning method comprises the following steps: enabling the terminal to send a UWB broadcast, and when the terminal receives a UWB signal fed back by a detected object to the UWB broadcast, determining whether the UWB signal passes through an obstacle; if the UWB signal passes through the obstacle, generating obstacle passing result information, and sending the result information to the detected object; when the measured object feeds back positioning data to the terminal according to the result information, enabling the terminal to obtain an original distance between the terminal and the measured object according to the positioning data; and correcting the original distance according to a preset correction parameter to obtain a corrected distance. According to the invention, whether the original distance is corrected or not is determined by judging whether the UWB signal sent by the measured object to the terminal passes through the obstacle or not, and the influence of the obstacle is removed to a certain extent, so that the corrected distance is further close to the actual distance, the measurement deviation is reduced, and the positioning precision is improved.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a UWB positioning method, a terminal, a computer readable storage medium. Background technique [0002] UWB technology began in the pulse communication technology initiated by the 1960s. UWB technology communicates with a wide range of ultra-wide band pulses, but also known as baseband communication technology, wireless carrier communication technology, mainly for military radar, positioning, and low intercept ratios / low detection rates. A communication system having a relative bandwidth greater than 0.2 or any time bandwidth is greater than 500 MHz is referred to as a UWB system. Since the UWB technology has the high data transmission rate (reaching 1Gbit / s), the anti-multi-diameter interference ability, low power consumption, low cost, low intercept ratios, and sharing spectra of existing wireless communication systems, etc., UWB technology becomes a pre...
