Design of Digital Landscape System Based on Panoramic Video Splicing Technology and Cloud Server

为实现效果更佳数字景观游览体验,提出一种基于全景视频和路径优化的数字景观游览系统。其中,在进行基于模型的虚拟场景搭建的同时,进行基于全景拼接技术的场景搭建,同时构建了基于LeanCloud云服务器的联网游览模块,使得游览更加接近真实游览场景;构建一种游览路径规划方法,并对其中的Cardinal曲线插值法进行优化,进一步提升路径规划质量。结果表明,与二次有理Bézier方法相比,改进的Cardinal曲线插值算法能够进行效果更好的路径优化,所优化后的曲线路径更加平滑;系统测试中,测试者们对游览系统的整体评价良好,验证了构建的系统的合理性。综上,构建的数字景观游览系统性能良好,整体设计合理,具有一定的实际使用价值。

To achieve a better digital landscape tourism experience,a digital landscape tourism system based on panoramic video and path optimization is proposed.Among them,while building virtual scenes based on models,scene construction based on panoramic stitching technology was also carried out,and a networked tour module based on LeanCloud cloud server was constructed to make the tour closer to real tour scenes;Construct a tourism path planning method and optimize the Cardinal curve interpolation method to further improve the quality of path planning.The results show that compared with the quadratic rational Bézier method,the improved Cardinal curve interpolation algorithm can perform better path optimization,and the optimized curve path is smoother;In the system testing,the testers gave a good overall evaluation of the tourism system,verifying the rationality of the constructed system.In summary,the constructed digital landscape tourism system has good performance,reasonable overall design,and certain practical value.
