Problems solved by technology

[0002] Nowadays, technology is changing with each passing day, and people have higher requirements for experience and ease of use. Among them, smart guides play an important role in guiding people to visit scenic spots, venues, supermarkets, etc., but the guides of existing technologies on the market One type of map is a flat map with only lines, and users with a poor sense of orientation cannot effectively use the guide; the other is a panoramic image to jump scenes, which has a poor experience
[0003] In the prior art, there is a map navigation method that uses plane pictures to display, which is a mainstream navigation method. Its implementation method is: collecting materials, making a plane map, and displaying it in the device. It has the advantage of simple implementation, but The shortcomings are: tourists can only watch, poor usability, and users with poor sense of position are difficult to use
[0012] Disadvantages of krpano panorama jumping: each jump needs to be clicked, the operation is complicated, one scene jumps, the scene transition is unnatural, and the experience is poor

Embodiment 1

[0057] The present invention proposes a 3D navigation method to realize 3D space navigation. The user can quickly and effectively find the route by moving in the real 3D environment. The operation is convenient, the navigation is practical, and the experience is strong. In particular, the following setting structure is adopted : Including the following specific steps:

[0058] 1) Make a 3D scene model;

[0059] 2) Realize the interactive function of walking;

[0060] 3) Write the data into the device to form a navigation map;

[0061] 4) Use of navigation maps.

Embodiment 2

[0063] The present embodiment is a further optimization on the basis of the above-mentioned embodiment, and further for realizing the present invention better, adopts the following setting mode in particular: described step 1) comprises the following specific steps:

[0064] 1.1) Make a 3D spatial structure model according to the building plan;

[0065] 1.2) Further make a spatial detail model of the guide route according to the real photos; the spatial detail model is used to restore the scene details, and can control the size of the 3D scene model, and preferably adopts the mode of proportional scaling to control the 3D scene model The size; that is, try to restore the details of the scene, and at the same time, consider controlling the size of the entire scene model to perform proportional scaling.

[0066] When implementing the present invention, the 3D scene model of the 3D guide needs to use modeling software such as 3D-MAX to build our scene model. The reason why we cho...

Embodiment 3

[0068] This embodiment is further optimized on the basis of any of the above-mentioned embodiments. In order to better realize the present invention, the following setting method is adopted in particular: the elements involved in the establishment of the 3D scene model include:

[0069] Scene: a three-dimensional space composed of models, materials and lights;

[0070] Material: including drawing material and shooting texture material;

[0071] Lighting: including ambient light and point light;

[0072] Camera: Perspective camera is used.

[0073] When building a 3D scene model, you need to configure the environment where the 3D scene model is located, including:

[0074] 1. Scene: a three-dimensional space where models, materials and lights are located

[0075] scene = new THREE. Scene();

[0076] 2. Lighting: including ambient light, point light source, etc.

[0077] var ambient = new THREE. AmbientLight(0xdddddd);

[0078] scene. add(ambient);

[0079] var PointLight...

Abstract

The invention discloses a 3D guidance method comprising the following specific steps of 1) making a 3D scene model; 2) achieving a walking interactive function; 3) writing data into a device to form aguidance map; and 4) using the guidance map. The method achieves 3D space guidance. A user can quickly and efficiently find a route by moving in a real 3D environment. The method is easy to operate and has good guidance practicability and good experience.

Description

technical field [0001] The invention relates to the fields of 3D technology and the like, specifically, a 3D navigation method. Background technique [0002] Nowadays, technology is changing with each passing day, and people have higher requirements for experience and ease of use. Among them, smart guides play an important role in guiding people to visit scenic spots, venues, supermarkets, etc., but the guides of existing technologies on the market One type of map is a flat map with only lines, and users with a poor sense of orientation cannot effectively use the guide; the other type is a panoramic image to jump scenes, which has a poor experience. [0003] In the prior art, there is a map navigation method that uses plane pictures to display, which is a mainstream navigation method. Its implementation method is: collecting materials, making a plane map, and displaying it in the device. It has the advantage of simple implementation, but The disadvantages are: tourists can ...
