简介:摘要:由于三维模型色调不一致,导致模型构建完整度和精准度较低,故提出基于倾斜影像与点云数据的古建筑三维模型构建方法。采用倾斜摄影技术获取古建筑倾斜影像,并通过相关信息配置与匀光匀色对其进行预处理。采用三维激光扫描仪获取古建筑点云数据,并通过精简算法对其进行预处理。采用最近点迭代算法(ICP)配准预处理后的倾斜影像与点云数据,以配准结果为基础,应用计算机生成的体系结构(CGA)规则进行古建筑三维模型的构建。实验结果显示:与现有方法相比较,提出方法三维模型构建完整度提升了11.57%,该方法的古建筑子部分三维模型构建完整度和精准度均较高,充分说明提出方法古建筑三维模型构建性能更好。
简介:摘要随着现代科技水平的不断发展与进步,大量的信息也随之增长,很多信息资料都需要能够保存很长时间,因此云计算应运而生,成为比较流行的全新的互联网应用模式。本文主要从云计算的相关技术概念入手,针对云计算和云数据管理进行相应的分析,然后展望云计算和云数据管理技术能够在生活中的应用,提出了这种高新技术的发展方向。
简介:no state is under obligation to recognize a nationality granted not meeting the requirements of it. In the Nottebohm case,the rules relating to the acquisition of its nationality. It is sometimes asserted that there must be a genuine and effective link between an individual and a state in order to establish a nationality which must be accepted by other states. It is doubtful,International Court of Justice first enunciated this principle and denied Liechtenstein the right to protect Nottebohm.III.
