Embodiment 1

[0049] The embodiment of the present invention provides a navigation method.

[0050] figure 1 is a flowchart of a navigation method according to an embodiment of the present invention. Such as figure 1 As shown, the navigation method includes the following steps:

[0051] Step S102, performing grid processing on the original path data of the indoor road network to obtain basic grid data.

[0052] In the technical solution provided by the above step S102 of the present invention, grid processing is performed on the original path data of the indoor road network to obtain basic grid data.

[0053] In the indoor environment, the original route data of the indoor road network is obtained, and the original route data includes information of each location in the indoor road network. After the original path data is obtained, the grid processing of the original path data is different from the traditional navigation method which adopts the concept of connected graph in graph theory...

Embodiment 2

[0107] The technical solutions of the present invention will be described below in conjunction with preferred embodiments.

[0108] The embodiment of the present invention relates to the establishment of a navigation road network model based on an earth space grid and a navigation method based on the road network model. Firstly, the use of navigation grid and two-dimensional code technology to determine the navigation position information and orientation is proposed, which can solve the problem that the current indoor navigation cannot use traditional navigation methods, thus making up for the vacancy of indoor application of navigation and path search.

[0109]In order to achieve the above purpose, the embodiment of the present invention uses the navigation grid and the two-dimensional code technology to determine the navigation position information and the guidance navigation method of the azimuth pointing, and preprocess the original indoor route data into a grid to obtain t...

Embodiment 3

[0130] The technical solution of the present invention will be described below in combination with optional embodiments.

[0131] figure 2 is a flowchart of another navigation method according to an embodiment of the present invention. Such as figure 2 As shown, the method includes the following steps:

[0132] Step S201, determine the final target grid G n and the starting grid G 0 .

[0133] Step S202, determine the final target grid G n and the starting grid G 0 Are they on the same floor.

[0134] In determining the final target grid G n and the starting grid G 0 After that, determine the final target grid G n and the starting grid G 0 Whether it is on the same floor, if it is judged that the final target grid G n and the starting grid G 0 Located on the same floor, execute step S203, if it is judged that the final target grid G n and the starting grid G 0 If they are not on the same floor, go to step S204.

[0135] Step S203, the current target grid G t...

Abstract

The invention discloses a navigation method and device. The method comprises the steps of performing gridding treatment on original path data of an indoor road network to obtain foundation grid data; determining a beginning position and a target position for navigating a target object; performing navigation calculation in the foundation grid data according to the beginning position and the target position to obtain a navigation direction; navigating the target object according to the navigation direction. The navigation method disclosed by the invention achieves an effect of reducing limit for navigating the target object.

Description

technical field [0001] The present invention relates to the field of navigation, in particular to a navigation method and device. Background technique [0002] At present, with the development of information technology and the popularization of location-based services (Location Based Service, LBS for short), more and more navigation applications appear in front of the general public. [0003] Using Geographic Information System (GIS for short) technology combined with electronic maps and mobile Internet terminals, modern life navigation can provide users with location-based information value-added services in terms of clothing, food, housing, and transportation. On the digital road network map constructed by geographic information system technology, combined with the global positioning system (GPS, BDS, GLONASS, Galileo), the user's real-time location can be grasped. Therefore, the use of the navigation system can provide users with the best travel route, for example, the t...
