中文摘要: 针对目前国内的全景漫游技术兼容性和实现效率差等问题,提出了一种基于WebGL的全景技术,免除安装渲染插件的步骤,系统更轻量,计算机资源占用率低.采取无人机航拍与地面全景云台架设相机拍摄相结合的方法收集数据;按照尺度不变特征转换的方式完成图片的拼接;结合WebGL技术和具体的HTML5框架添加场景和制作热点数据,上传至服务器端完成发布.该技术成功应用于桂平市智慧旅游建设项目当中,实现了景区的全景虚拟漫游系统.通过该系统,用户可在线虚拟游览欣赏景区的景点风光,体验全景漫游的沉浸感和逼真性.
Abstract:In view of the current domestic panoramic roaming technology compatibility and poor implementation efficiency, this study proposes a panoramic technology based on WebGL, which eliminates the installation of rendering plug-ins. The system is more lightweight and has lower computer resource usage. Firstly, data is collected by combining the aerial photography by unmanned aerial vehicle and ground point shooting. Then, image splicing process is performed with scale-invariant feature transform. Finally, WebGL technology is adopted to combine with specific HTML5 framework to add scenes and make hot data, which are uploaded to the server to complete the publication. It is successfully applying to Guiping smart tourism construction project. Through this system, users can enjoy the scenery of scenic spots on the online virtual tour, and experience the immersion of panoramic roaming.
