Indoor positioning method based on three-dimensional environment model matching

Abstract

The invention discloses an indoor positioning method based on three-dimensional environment model matching. Indoor environment modeling, position analysis and information calibration are carried out by three-dimensional information acquired by a sensor; a user collects current scene information and performs quick comparison and precise feature matching on the current scene information and three-dimensional environment model information to realize indoor positioning of the user. The positioning method cannot be finished until a data acquisition device and a data analysis platform for indoor positioning are respectively built. The data acquisition device comprises but not limited to an RGB-D (red, green and blue-D) sensor, an inertia measurement sensor and the like and can finish acquiring space information such as three-dimensional information, the attitude and a deflection angle at any indoor position; the data analysis platform can carry out quick storage, position analysis and information calibration on the environment model by the acquired three-dimensional information and feed back an analyzed positioning result to a user; therefore, the indoor positioning function is realized.

Description

technical field [0001] The invention relates to an indoor positioning method in the field of computer pattern recognition, in particular to an indoor positioning method based on three-dimensional environment model matching. Background technique [0002] Indoor positioning technology refers to the realization of position positioning in an indoor environment. At present, wireless communication, base station positioning, inertial measurement positioning and other technologies are mainly used to integrate a set of indoor position positioning system, so as to realize the position monitoring of users in indoor space. Reliable and accurate indoor positioning technology has broad market prospects in commercial applications, public security, and home services, and it is also one of the hot research technologies at present. In commercial applications, indoor positioning technology can be used to help users conduct store shopping guides and push accurate product information in shoppin...

AI Technical Summary

Problems solved by technology

[0004] Due to the existing technology, the indoor positioning service provider needs to deploy a large number of transponders or beacons in the room where positioning is required in advance to receive the user’s transmission signal in real time, and requires the object or user to be tested to install or wear the same sensor at the same time. The high-tech signal transmitting or collecting device makes the hardware cost of the current indoor positioning service high, and the use and maintenance are also very inconvenient

In addition, since the deployed transponders have certain restrictions on the conditions of the deployment area, service providers are also required to conduct relatively accurate indoor plane mapping, which further increases the service cost of indoor positioning.
