Problems solved by technology

At the same time, most of the existing navigation solutions focus on the shortest navigation path, or simply divide them into walking, self-driving, and bus options, making walking navigation unable to meet the individual needs of users.

Embodiment Construction

[0069] Such as figure 1 Shown, a kind of self-adaptive walking navigation method based on virtual reality, it comprises the following steps:

[0070] S1. Extract feature information of scenic spot landmarks and establish three-dimensional models of scenic spot landmarks; preset scene mode, generate mapping table of three-dimensional model of scenic spot landmarks and scene mode information; store three-dimensional model and mapping table of scenic spot landmarks in scenic spot database; The labels corresponding to various road sections are set in advance, and the weights are set for each label; the labels corresponding to the road sections and the weights of the labels are stored in the user personalized database.

[0071] 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 als...

Abstract

The invention provides a self-adaptive 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, S2, acquiring information of navigation starting and ending points input by a user and a scene mode selected by the user, acquiring a navigation path, and acquiring three-dimensional information of buildings on the navigation path; S3, based on the scene mode selected by the user, selecting the three-dimensional models of all the sight spot landmarks in the scene mode as a candidate set through mapping; 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; S5, mixing virtual and actual reality and displaying the navigation path on VR equipment; S6, acquiring the label of a navigation path section that a user chooses to correct, increasing the weight of the label and updating the weight corresponding to the label of the navigation path section; and S7, acquiring information of navigation starting and ending points input by a user again and repeating S2 to S6.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an adaptive 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...
