摘　　要：随着虚拟现实技术的成熟,文化遗产数字化保护与传承越来越受到人们的关注。通过GPS定位与移动终端的结合,实现智能移动终端GPS在展示古迹废墟遗址方面的优势。具体方法是,首先通过数据转换,建立虚拟场景与真实场景的区域映射;然后使用陀螺仪将摄像机的角度与智能移动终端绑定,建立虚拟角色与现实角色的姿态映射,最后通过Unity3D插件包实现虚实漫游功能,打破时间与空间限制,丰富展示作品的信息量与趣味性,并提供一种个性化的文化遗产场景浏览模式,可应用于遗址废墟如圆明园场景。The paper focuses on the integration of GPS positioning technology with the emerging intelligent mobile terminal, realizing the function of cell phone GPS extension and highlighting the unique advantage in the aspect of ruins displaying. The following is the specific method, firstly, establish the region mapping of virtual scene and real scene through the data conversion; then bind the camera angle and handheld devices by using the gyroscope and set up posture mapping between virtual character and reality role; finally achieve the virtual-real roaming through plugin package Unity3D. The method breaks the limitation of time and space, enriches the information content and the interestingness of works, and provides a personalized browse mode of cultural heritage scenes. It could be applied on some ruins＇ scenes such as Yuanmingyuan Imperial Garden.
