Abstract

The present application relates to an indoor positioning and navigation method, device, storage medium and computer equipment. The attitude information of the pedestrian is obtained according to the heading and attitude reference system AHRS, and the attitude information is input into the pedestrian dead reckoning system PDR for processing to obtain the motion model of the pedestrian. According to the obtained dominant frequency of the target fluorescent lamp in the current environment, the indoor position of the target fluorescent lamp is determined. In the particle filter, the pedestrian's motion model is combined with the indoor position of the target fluorescent lamp to locate the pedestrian. With the help of the spectral characteristics of different fluorescent lamps in the environment, the identification of fluorescent lamps is realized, and the position of fluorescent lamps is used as a visual landmark to provide absolute position reference for the entire positioning system, and the cumulative error of PDR is continuously corrected to achieve high-precision continuous position. There is no need to replace existing lighting facilities, which greatly reduces costs.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an indoor positioning and navigation method, device, storage medium and computer equipment. Background technique [0002] Indoor positioning and navigation technologies are widely used in the production and life of modern society, such as the positioning and navigation of automated warehousing and logistics robots, the positioning of smart supermarket shopping carts, and the positioning and navigation of personnel in large indoor scenes. Although the current indoor positioning and navigation technologies are flourishing, they have not yet solved the game problem of positioning and navigation accuracy and cost. The indoor positioning technology based on visible light communication using modulated LED lighting fixtures can provide sub-meter positioning accuracy, but it needs to modify or replace existing lighting facilities, which will undoubtedly cost a lot of cost and time. C...
