Problems solved by technology

However, when using these interactive devices for virtual scene interactive experience, users still need to control them with their hands. At the same time, because different devices have only a few specific functions, when the system needs to realize multiple functions, it often needs to be equipped with multiple interactive devices. Users have to switch between different devices to perform different virtual experience functions
Therefore, this interaction method also has the disadvantages of being unnatural and inflexible.

Embodiment 1

[0037] Flowchart such as figure 1 An interactive design and experience method for a virtual agricultural park shown in , mainly includes the following steps:

[0038] S1. Construct the basic 3D scene template library of the agricultural park and the 3D model of landscape elements, and divide each basic 3D scene into functional areas; this step mainly includes the following steps:

[0039] S101. Generate several basic 3D scenes of agricultural parks by means of interactive design methods or general-purpose 3D design software (such as 3DSMax). Each basic 3D scene includes basic elements such as terrain, ponds, rivers, and grasslands, and Save all the basic 3D scenes of the agricultural park to the 3D scene template library of the computer database module.

[0040] S102. Divide the functional area of ​​the basic three-dimensional scene of the agricultural park to form a functional area division of the agricultural park for different application requirements such as animal husban...

Embodiment 2

[0057] The present invention also provides a virtual agricultural park interactive design and experience system for realizing the above method:

[0058] An interactive design and experience system for a virtual agricultural park, including a gesture capture device, a gesture recognition module, a logic control module, a database module, and a display terminal;

[0059] Gesture capture device, which captures user gesture information in real time and sends it to the gesture recognition module;

[0060] The gesture recognition module converts gesture information into digital information and feeds it back to the logic control module;

[0061] The database module stores the basic three-dimensional scene template library of the agricultural park, the functional area division information of the basic three-dimensional scene, the three-dimensional model of the landscape element, and the auxiliary information of text and image;

[0062] The logic control module selects and operates co...

Abstract

The invention relates to the technical field of virtual reality, and particularly relates to an interactive design and experience method of a virtual agricultural park and a system. First, a basic three-dimensional scene template base and a landscape element three-dimensional template of the virtual agricultural park are built, each basic three-dimensional scene is divided into functional areas, then, gestures selection of a user is tracked and identified to show a corresponding basic three-dimensional scene, and then, landscape element selection, dragging and dropping and rotating gestures of the user are continuously tracked and identified to respective show, shift and rotate landscape element three-dimensional templates corresponding to the gestures. The interactive design and experience method of the virtual agricultural park and the system can fully use convenience of human body gesture motion to ensure that interactive designs and experience of the virtual agricultural park are more natural and has more enjoyment, and satisfy application requirements of aided designs of the virtual agricultural park, virtual experience of farm operations and science popularization education to ensure that the user has more immersion. Meanwhile, the interactive design and experience method of the virtual agricultural park and the system have the advantages of being simple, easy to use and low in cost.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a gesture recognition-based interactive design and experience method and system for a virtual agricultural park. Background technique [0002] The design and interactive experience of the virtual agricultural park has important application value in the auxiliary planning and design of the agricultural park, the preview of the construction effect, and the comparison of the schemes. Especially in recent years, with the rapid development of virtual reality technology, researchers have developed various 3D modeling software tools and virtual scene interactive devices, making the interactive design and virtual experience based on 3D visualization widely used in various fields. [0003] At present, the design of virtual scenes is mostly implemented by commercial 3D modeling software and visual simulation systems; some people combine programming languages ​​and graphics process...
