Embodiment Construction

[0061] Such as figure 1 Shown, a kind of improved walking navigation method based on virtual reality, it comprises the following steps:

[0062] S1. Extract feature information of scenic spots and landmarks and build three-dimensional models of scenic spots and landmarks; preset scene mode, generate mapping tables of three-dimensional models of scenic spots and landmarks and scene mode information; store three-dimensional models and mapping tables of scenic spots and landmarks in scenic spots database.

[0063] The scenic spot landmark may be a famous mountain, a famous building, an artificial scenic spot, and the like. According to the characteristics of these landmarks, scene modes such as natural scenery, high-rise buildings, historical buildings, etc., can also be further divided in combination with the style of the building, such as European style, southern town, etc., can be pre-set.

[0064] S2. Obtain the navigation start point and end point information input by the u...

Abstract

The invention provides an improved navigation method for walking based on virtual reality. The method comprises the following steps: S1, extracting characteristic information of sight spot landmarks, establishing three-dimensional models of the sight spot landmarks, presetting scene modes and generating a mapping table for the three-dimensional models of the sight spot landmarks and information of the scene modes; S2, acquiring information of navigation starting and ending points input by a user and a scene mode selected by the user, generating preliminary navigation path sections according to the information of the navigation starting and ending points, correcting the preliminary navigation path sections according to the option of the user so as to obtain a navigation path, and acquiring three-dimensional information of buildings on the navigation path; S3, using the three-dimensional models of all the sight spot landmarks in the scene mode as a candidate set; S4, screening out the three-dimensional model of a sight spot landmark matching with the length of the navigation path and the three-dimensional information of the buildings from the candidate set according to the length of the navigation path and the three-dimensional information of the buildings; and S5, mixing virtual and actual reality and displaying the navigation path on VR equipment.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an improved walking navigation method and system based on virtual reality. Background technique [0002] Navigation equipment refers to equipment that uses a positioning system to provide route guidance for moving objects such as vehicles. Existing navigation equipment mainly utilizes a positioning system to provide navigation services for users. Specifically, the navigation device provides the user with a navigation map, in which a navigation path and an estimated time-consuming time from the current location to the destination are displayed. [0003] Virtual reality (virtual reality, VR) technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment, which is an interactive 3D dynamic scene and entity behavior system that combines multi-source information Simulation immerses the user in that...
