Abstract

The invention discloses an indoor positioning and auxiliary navigation method, a device and a system based on iBeacon. The method comprises the following steps of: receiving broadcast information sentby a plurality of iBeacon devices, the broadcast information of each iBeacon device including the location information of the iBeacon device and the device number; calculating distances between the plurality of iBeacon devices and the user device, selecting a first iBeacon device and a second iBeacon device closest to the iBeacon device; at least one additional iBeacon device is determined basedon the first iBeacon device and the second iBeacon device, and the current location of the user device is determined using a triangular centroid positioning method. The invention can better realize indoor accurate positioning, and can be effectively applied to parking lots or other actual indoor scenes.

Description

technical field [0001] The present invention relates to the field of positioning and navigation, in particular to an iBeacon-based indoor positioning and auxiliary navigation method, device and system. Background technique [0002] With the continuous changes in daily life, people's demand for indoor positioning technology is becoming more and more urgent. Indoor positioning technology has broad application prospects in large shopping malls, parking lots and other scenarios. The indoor positioning technology that can achieve high real-time performance, high precision, and low cost has received more and more attention and research. [0003] One of the current mainstream indoor positioning technologies is an iBeacon-based positioning solution. This solution is based on the low-power Bluetooth module solution. By arranging iBeacon devices in an indoor environment, a base station topology is established, and smart devices realize location confirmation by receiving signals from ...
