Embodiment Construction

[0044]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] The present invention uses the positioning technology based on identification of markers to locate the user and its target position, and finds the shortest route from the user's current position to the target position according to the routing algorithm. Sensors such as gauges calculate the user's direction and displacement, and complete real-time tracking of the user's location.

[0046] see figure 1 , which is a flowchart of a method for indoor navigation i...

Abstract

The invention discloses an indoor navigation method including: locating a user and a target location by the aid of the location technique based on marker recognition; finding out the shortest route from the user current location to a parking place according to the routing algorithm; and computing the direction and the displacement of a user by the aid of an internal sensor of an intelligent terminal during user movement, so that real-time tracking of the user location is completed. The invention further discloses an indoor navigation system, a navigation client-side system and the intelligent terminal. Based on marker recognition and by combining direction and acceleration sensor data for locating and navigation, the method and the systems are high in precision, low in cost and insusceptible to external signals.

Description

technical field [0001] The present invention relates to the field of navigation, in particular to an indoor navigation method, system and equipment. Background technique [0002] In recent years, the application of LBS (Location Based Service, location-based service) has gradually become a hot spot, and the navigation technology has developed rapidly. GPS positioning can provide users with a lot of auxiliary information for outdoor positioning and navigation, but it also has obvious defects, that is, in the indoor environment, GPS positioning speed is extremely slow, and the accuracy is low, and even the positioning cannot be completed. Therefore, indoor navigation technology has gradually become a research hotspot. Different from outdoor navigation, indoor navigation technology mainly uses technologies such as wireless network positioning or radio frequency identification for positioning, which solves many problems in the application of GPS indoors. [0003] Among the exi...
