Abstract

The embodiment of the invention provides an indoor navigation method and system. The method comprises the steps of determining a current position of a movable target based on an ultra-wideband positioning technology, constructing a corresponding map for an indoor space where the movable target is located, and establishing a corresponding rasterized coordinate system for the map,wherein the rasterized coordinate system divides the map into a plurality of grids, each grid has a corresponding pass factor, and the pass factor is used for representing whether the corresponding grid is passable or not, determining a plurality of passable paths from the current position to the destination position in a map according to the current position and the destination position of the movable target, wherein the passable path comprises a plurality of continuous grids from the current position to the destination position, and determining one passablepath for the movable target in the plurality of passable paths. According to the method and the system provided by the embodiment of the invention, indoor navigation is carried out on the blind through an ultra-wideband positioning technology, and the method and the system have the advantages of high positioning navigation obstacle avoidance precision, simple algorithm, low cost and the like.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to an indoor navigation method and system. Background technique [0002] There are many obstacles in the indoor space, such as steps, elevators, etc. The visually impaired people are likely to encounter various obstacles when walking indoors. Therefore, effective navigation and obstacle avoidance methods are needed to assist the visually impaired people to walk in the indoor space. [0003] At present, the methods of navigation and obstacle avoidance in outdoor spaces are relatively mature, but the accuracy of navigation and obstacle avoidance methods in indoor spaces is low. Therefore, it is urgent to provide a navigation and obstacle avoidance method suitable for indoor spaces with high accuracy. Contents of the invention [0004] Aiming at the problems existing in the prior art, embodiments of the present invention provide an indoor navigation method and system. ...
