Abstract

The present invention discloses a Bluetooth 5-based indoor positioning and navigation method. According to the invention, the positioning of an indoor positioning device is subjected to error analysis, and a Bluetooth 5-based indoor accurate positioning and navigation method is provided. The method comprises the following steps of 1, establishing an indoor position fingerprint database, wherein the indoor position fingerprint database is mainly composed of the geographic position coordinates of a reference point, the signal strength RSSI of a signal broadcasted by a Bluetooth signal transmitting module, and the corresponding ID of the Bluetooth signal transmitting module; 2, conducting the indoor positioning and navigation by using the Bluetooth technology, broadcasting a signal by the Bluetooth signal transmitting module, receiving the signal by the positioning device, matching the received signal with the indoor position fingerprint database and obtaining the coordinates of a positioning point; 3, correcting the positioning error of the positioning device itself, obtaining a preliminary positioning track through the self-positioning of the positioning device, and correcting the track by using the coordinates of an accurate positioning point. The method is low in cost, high in precision, and low in power consumption. The method can be widely applied to the indoor accurate positioning and navigation field.

Description

technical field [0001] The present invention relates to the technical field of positioning and navigation, and more specifically, to a Bluetooth 5-based indoor positioning and navigation method. Background technique [0002] In recent years, with the vigorous development of "Internet of Things" technology, various spatial location positioning technologies and related systems are in rapid development. At present, the "GPS" positioning system and the "Beidou" positioning system are widely used in positioning and navigation. However, the signal strength of the above two positioning system signals is greatly attenuated due to the shielding effect of buildings, which seriously affects the indoor positioning accuracy. Therefore, how to achieve accurate indoor positioning has become an important topic of research in various fields and research institutions. [0003] At present, the mainstream indoor positioning methods mainly include: ZigBee technology, infrared technology, ultra...
