Problems solved by technology

[0004] Traditional GPS has low precision and cannot be used indoors or in environments with large building blocks. The target tracking technology based on monocular vision has a large amount of calculation, cannot be tracked by blocks, and is difficult to recover the relative position information of the target. Problem Although the Bluetooth and RFID positioning technologies are less disturbed by the environment, they have a short operating dis

Abstract

The present invention provides an ultra-wideband-based automatic following fast positioning method. The method mainly comprises the following steps of: calculating a relative distance between two basestations and a tag by measuring timestamps of transmitting and receiving data packets between the tag and the base stations, estimating an optical value of the distance through multiple filtering, rapidly calculating a distance from a platform equipped with the base stations to the tag and a relative angle, locating the position of the tag, and calculating the distance and the relative angle. Theultra-wideband-based automatic following fast positioning method achieves a fast and efficient positioning mode and reduces the calculation amount.

Description

technical field [0001] The invention belongs to the application field of positioning following technology, in particular to an ultra-wideband-based automatic following fast positioning method. Background technique [0002] UWB (Ultra-Wideband) ultra-wideband, initially using pulse radio technology, this technology can be traced back to the 19th century. Later, major companies such as Intel proposed the MB-OFDM technology solution using UWB. Because the two solutions are completely different, and each has strong camp support, the 802.15. Decide on the final standard solution, then leave it to the market to resolve. In order to further increase the data rate, UWB applies ultra-short baseband rich GHz-level spectrum. UWB was used in short-distance high-speed data transmission in the early days. In recent years, foreign countries have begun to use its sub-nanosecond ultra-narrow pulse for short-distance precise indoor positioning. [0003] UWB (Ultra Wideband) wireless commun...
