Game Design

1. Introduction

The purpose of designing this application is not only to allow people to visit the model and landscape remotely online, but also to solve the problem that in today's overpopulated environment, a large number of tourists will come to the local landscape, which will have a negative impact on the local environment. Destruction and pollution of the environment and historical sites.

2. Description of the application

In France, the tourism industry emitted 118 million tons of carbon dioxide in 2018. These greenhouse gas emissions are equivalent to the annual greenhouse gas emissions of 11 million French people. These emissions come mainly from transport and accommodation, but also from other tourism activities such as restaurants and shopping. Tourists account for 80% of transport-related greenhouse gas emissions (primarily air transport), and this air pollution contributes significantly to global warming and changes air quality. In addition, a large number of tourists will also lead to the saturation of transportation networks and streets, and the crowded accommodation environment will lead to an increase in real estate and living costs, affecting the living standards of local residents. This application is designed to display virtual models in reality, provide people with an intuitive visual experience, and can also interact with the scene to increase the fun of the experience.

Digital technology has significantly influenced the evolution of cultural heritage dissemination, leading to the advent of new research branches [1,2]. AR, which combines real and virtual objects in an environment with real-time operation [3,4], constitutes a source of innovation to co-create enhanced CH experiences [5].

Augmented Reality (AR for short) refers to a technology that uses information that does not originally exist in a certain area of the real world based on a certain medium and is simulated and then superimposed onto the real world. ultimately perceived by human senses. Different from VR, AR only requires a mobile phone device to realize simple virtual interaction functions around you, while VR requires expensive and complex head-mounted devices. This application uses AR to display famous classic buildings. In this form, you only need to use the camera of your mobile phone to scan a specific picture, and the 3D model of the local building will pop up on your mobile phone. In this way, people can visit cultural heritage around the world without leaving home, which greatly reduces the cost of Too many tourists have a negative impact on the local area.

Use the mobile phone camera to capture the graphics card of cultural heritage, capture the identification mark through computer vision technology, record its position and direction in real time, and the virtual 3D model objects stored in the data platform are superimposed with the real scene. This is accomplished by detecting the matching of natural feature points, saving the feature points detected in the recognition map in the database, and then matching the feature points detected in real time in the real image with the feature point data of the recognition map in the database to achieve virtuality and reality overlay of scenes.

3. Interaction Design

The software can create a virtual 3D model by identifying real-life pictures. Users can have a 360-degree look around the model. This allows users to experience the magnificence of cultural heritage more immersively and intuitively. Not only Avoiding offline crowd congestion also indirectly protects these landscapes.

Users only need to touch the screen with their fingertips to observe and feel the landscape in real time, and rotate the landscape model by dragging the screen. This interactive design is to make the software easier to use and more attractive, which greatly It enriches people's lifestyle.

5. Technical Development

The application is developed using Unity2021.3.3f1, and adds the Vuforia package for augmented reality functions. Vuforia's Target Manager is a web tool for creating and managing object database. By creating a database, you can enter the database to add identification object target, upload the pictures of the Eiffel Tower and the Leaning Tower of Pisa to the Database and save them, and finally package and run them in Unity. By creating an Image Target object and adding corresponding pictures, the picture recognition function can be realized. When the camera recognizes the image, it will display a model of the Eiffel Tower that can be browsed around.

6. Descriptions of 3D Models

This application uses two models for display and interaction.
