Description

Technical Field

[0001] The invention relates to the technical field of tourist map navigation, in particular to a 3D real-scene tourist map navigation explanation updating method. Background Art

[0002] With the development of tourism, more and more tourists hope to get real-time and accurate navigation and explanation services during their travels. Existing tourist map navigation technology mainly relies on GPS positioning, but in some scenic spots, especially indoors or in areas with complex terrain, the GPS signal is weak, resulting in inaccurate positioning and poor navigation results. In addition, existing navigation and explanation systems often cannot provide targeted scenic spot explanations based on the user's location, and the user experience needs to be improved. Summary of the invention

[0003] The present invention aims to provide a 3D real-life tourist map navigation explanation updating method, which mainly includes the following three aspects: 1. Graphical road network planning: Users generate road networks by drawing lines and set attributes for the drawn lines to achieve customized route planning.

[0004] 2. Positioning and navigation based on GPS and magnetic field signals: Based on GPS positioning, magnetic field signals are used for secondary positioning to improve positioning accuracy.

[0005] 3. AR feature recognition and automated explanation: During the user's navigation process, the scene is captured by the camera to achieve automated explanation of the scenic spots. DETAILED DESCRIPTION

[0006] 1. Graphical road network planning implementation method (1) The user selects the starting point and the end point on the map interface; (2) The user draws a route using a line drawing tool and sets route attributes (such as one-way street, two-way street, lane for vehicles, lane for pedestrians, etc.); (3) The system generates the shortest route based on the route attributes set by the user.

[0007] 2. Positioning and navigation implementation based on GPS and magnetic field signals (1) During navigation, the system obtains GPS positioning information in real time; (2) The system collects magnetic field signals at multiple locations of scenic spots and establishes a magnetic field signal database; (3) Match the magnetic field signal collected in real time with the signal in the database to achieve secondary positioning.

[0008] 3. AR feature recognition automation explanation implementation method (1) The system detects that there are multiple scenic spot explanation points near the user; (2) Remind the user to turn on the camera; (3) Through the AR feature recognition algorithm, the scene in the user's camera image is identified and the explanation content of the corresponding scenic spot is automatically played.

[0009] The present invention has high versatility, practicality and convenience, and is suitable for navigation and explanation needs of various tourist attractions. Through the above implementation modes, the present invention can provide users with real-time and accurate navigation and explanation services, and improve user experience.
