Abstract

The invention discloses an indoor positioning method, an indoor positioning device, indoor positioning equipment and a storage medium. The indoor positioning method comprises the following steps: acquiring the signal intensity and position of a currently searched Bluetooth node; Determining a plurality of candidate Bluetooth nodes according to the signal strength of the Bluetooth nodes and a preset threshold value; Calculating the density coefficient of each candidate Bluetooth node according to the coverage area of each candidate Bluetooth node; Calculating the weight of each candidate Bluetooth node according to the signal strength of each candidate Bluetooth node and the corresponding density coefficient; Calculating the position of the mobile terminal according to the position of eachcandidate Bluetooth node and the corresponding weight; Density compensation is performed by constructing the density coefficient of the Bluetooth nodes, so that the compensated Bluetooth nodes are balanced, positioning errors caused by non-uniformity of the Bluetooth nodes or abnormality of part of the Bluetooth nodes can be effectively reduced, and the positioning accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to an indoor positioning method, device, equipment and storage medium. Background technique [0002] At present, the existing mobile phone Bluetooth indoor positioning technology uses several Bluetooth devices evenly arranged in an indoor area for transmitting Bluetooth signals. In the actual positioning process, when the mobile phone acquires a sufficient number of Bluetooth devices that meet the signal strength requirements, the Bluetooth devices collected online by the mobile phone are assigned weights according to the signal strength value, and then the coordinates of each Bluetooth device are weighted to estimate the orientation of the mobile phone information. [0003] However, due to the blind spots where Bluetooth devices cannot be installed in the indoor space of the building, the Bluetooth nodes cannot be evenly arranged in the indoor space area; The e...
