Embodiment

[0040] refer to figure 1 , an indoor and outdoor intelligent navigation system, comprising,

[0041] Map building module: used for indoor floor and outdoor map modeling to obtain the final map,

[0042] like figure 2As shown, the process of building a map is as follows: In the SVE Cloud 3D scene editor, first build a blank scene, and then create floors. In this example, create 5 floors, and import the CAD building plan of each floor into the SVE Cloud 3D scene editor. Adjust the ratio of the distance between two points on the cad plan and the actual distance between two points, draw walls, floor tiles, doors, place tables, chairs and other interior decorations on the floor, and then set them up in toilets, stairs, elevators and important rooms POI points, finally exported to get the final map;

[0043] Bluetooth positioning module: used for users to locate their position on the map during use,

[0044] The process of Bluetooth positioning is as follows:

[0045] The firs...

Abstract

The invention discloses an indoor and outdoor intelligent navigation system, which comprises a map establishing module used for indoor floor and outdoor map modeling to obtain a final map; a Bluetoothpositioning module which is used for positioning the position of the user on the map in the use process; a path navigation module which is used for realizing cross-floor accurate positioning in an indoor map and GPS positioning of an outdoor map based on a road network optimal path algorithm of an A * algorithm; and a voice broadcasting module which is used for broadcasting indoor and outdoor symbolic buildings or positioning places on a map in real time. The navigation system can achieve the indoor and outdoor high-precision positioning effect, and is low in cost, low in power consumption, high in connection speed and high in connection stability.

Description

technical field [0001] The invention relates to navigation technology, in particular to an indoor and outdoor intelligent navigation system. Background technique [0002] At present, GPS navigation and positioning technology basically meets people's needs for location services in outdoor scenarios, but in indoor scenarios, the following problems often occur: [0003] 1. It is difficult to find a specific room number on a specific floor: [0004] When using GPS navigation to locate the building that needs to be reached, it is difficult to quickly and accurately locate the specific room number of a certain floor that needs to be reached, and it is easy to get lost and waste time in the process of searching. [0005] 2. Difficult to find the bathroom: [0006] There are few signs of toilets (public facilities) provided indoors, and even if there are, it is difficult to determine which toilet is closer to the current location. Contents of the invention [0007] The object o...
