Abstract

The invention discloses a positioning method, device and system in an indoor environment, relates to the technical field of positioning and has the main purpose of realizing the precise positioning inthe indoor environment. The main technical scheme provided by the invention comprises the steps of receiving current indoor image information sent by a mobile terminal and extracting visual featuresin the current indoor image information; matching the visual features with key frames in an offline map database, and determining candidate key frames similar to the visual features; and determining poses corresponding to the candidate key frames, converting the poses into coordinate values, and sending the coordinate values to the mobile terminal.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a positioning method, device and system in an indoor environment. Background technique [0002] Most of the traditional positioning methods need to locate users through GPS satellite positioning. With the development of cities, the scale of buildings is getting larger and larger, and people's demand for indoor positioning is increasing. [0003] At present, due to the poor ability to receive GPS signals indoors, the GPS positioning is inaccurate or the GPS positioning system cannot be used. Therefore, the authenticity and accuracy of GPS positioning data cannot meet indoor commercial needs. Contents of the invention [0004] In view of this, the present invention provides a positioning method, device and system in an indoor environment, the main purpose of which is to achieve precise positioning in an indoor environment. [0005] In order to solve the above prob...
