Indoor navigation system and method

Abstract

The invention provides an indoor navigation system and method. The method is performed based on smart glasses and comprises the steps as follows: S1, a positioning sensor unit is adopted to acquire position information of a user; S2, a departure position and a destination position of the user are set in a navigation calculating unit according to the acquired position information of the user; S3, according to the departure position and the destination position of the user and in combination of an indoor map, the navigation calculating unit is adopted to calculate a navigation path between the two positions; S4, a data processing unit is adopted to perform real-time matching coverage between the indoor map navigation path and the real scene with a geometric projection method; and S5, an indicating unit is adopted to indicate the navigation path. According to the indoor navigation system and method, due to introduction of the smart glasses, the whole navigation system structure is simplified, the cost is reduced, furthermore, navigation information can be presented for the user in a more visual and humanized manner, and the overall system is higher in practicability and portability.

Description

technical field [0001] The invention relates to navigation technology, in particular to an indoor navigation system and method. Background technique [0002] Navigation systems are a booming field in this century. At present, outdoor navigation mainly relies on satellite positioning, and has achieved great success in car navigation, civil construction, and military applications, but the indoor navigation system is still not mature enough. [0003] Indoor navigation can also use satellite navigation, but due to the large attenuation of satellite signals indoors, external hardware networks need to be used for signal compensation and calibration, which is less practical, which is why indoor positioning technology requires other technical means to achieve. At present, the main technical means are inertial navigation through sensor groups or real-time positioning and navigation combined with wireless signals. The main implementation clients are mainly concentrated on mobile devi...

AI Technical Summary

Problems solved by technology

[0007] 1. When the system uses the server-location network-client structure, it will inevitably lead to high complexity of the system, especially when multiple users use real-time navigation, the performance requirements of the server are high, and the cost is also high;

[0008] 2. Since it is cumbersome to make a real 3D electronic map, each indoor structure requires professionals and the workload is heavy, so it is inconvenient to promote it on a large scale in practical applications;

[0009] 3. The server needs to maintain communication with the client at any time to ensure the stability of the navigation work. The navigation system needs to be in working condition all the time. In the case of infrequent startup, the server is not used frequently, which may cause a certain waste of equipment and poor cost performance;

[0010] 4. Due to the limitation of the display function of traditional smart devices, users usually need to hold the device, and the navigation direction can be confirmed only by comparing the real environment with the device navigation information, which is not humanized enough.
