摘　　要：随着现代旅游的发展,以增强现实为基础的虚拟旅游得到了广泛应用,促使文化旅游产品得到推广和应用。针对增强现实技术在文化旅游资源方面的应用,沉浸式数字旅游系统以旅游特色明信片为基础,结合基于SIFT自然特征的增强现实技术,在真实的明信片上叠加虚拟场景以达到虚实融合的效果。同时,利用Unity3D处理在移动设备上的触控操作,实现单指旋转、双指缩放等交互操作,最后达到能够在真实场景中对数字文化内容进行智能交互的效果。With the development of modern tourism, virtual tourism based on augmented reality has been widely applied, which has promoted the promotion and application of cultural tourism products. In view of the application of augmented reality technology in cultural tourism resources, immersive digital tourism system is based on the postcard with the characteristic of tourism, combined with augmented reality technology based on SIFT natural features, adding virtual scenes to real postcards, to achieve integration of virtual and real. At the same time, using Unity3 D to handle the touch operation on the mobile device, realize the interactive operation of single finger rotation and double finger zoom, and finally achieve the effect of intelligent interaction of digital culture content in real scene.
