摘 要: 针对传统的智慧旅游微缩模型场景设计方法中微缩场景设计精度低的问题,提出一种基于三维激光和AR技术的智慧旅游微缩模型场景设计方法。利用三维激光扫描技术获得旅游场景的三维点云数据,使用统计量描述场景特征,根据场景特征采用目标作用距离计算方法计算微缩模型场景距离。在此基础上,采用分层制作的方法,将旅游场景分为多个模块与子场景,结合得到的模型场景距离,得出智慧旅游微缩模型场景。实验对比结果表明,此次提出的基于三维激光和AR技术的智慧旅游微缩模型场景设计方法比传统的方法微缩场景设计精度高,实际应用意义更强。

Abstract: A method of smart tourism miniature model scene design based on 3D laser and AR technology is proposed to improve the precision of miniature scene in the traditional smart tourism miniature model scene design method. The 3D point cloud data of tourism scenes are obtained by means of 3D laser scanning technology, the scene features are described with statistic, and the scene distances of miniature model are calculated by means of the target operating distance calculation method according to the scene features. On this basis, the tourism scene is divided into several modules and sub?scene by means of the method of hierarchical production, and the smart tourism miniature model scene is obtained by combining the obtained model scene distance. The experimental results show that the proposed method of smart tourism miniature model scene design based on 3D laser and AR technology has higher precision in the miniature scene design than that of the traditional method, which has stronger practical application.
