摘要
随着我国重大活动保障任务的持续增加,建筑三维建模技术的核心支撑作用愈发凸显。本文以北京市某区开展的重大活动安全保障三维建模项目为例,对道路沿线建筑物开展精细化分层分户建模,系统阐述了模型在重大活动保障中的构建方法与实际应用。研究聚焦矢量图纸法和三维激光扫描法两种建模方法,从数据获取方式、建模成本、作业效率、精度控制、适用场景及后期数据更新等维度进行对比分析,揭示不同建模技术路径的优势差异。在重大活动保障实践中,建筑三维模型技术在制高点应用、多视域场景分析等方面展现出关键的价值。
With the continuous increase in major event security tasks in China,the core supporting role of three-dimensional(3D)building modeling technology has become increasingly prominent.The 3D modeling project for security assurance dur⁃ing a major event in a district of Beijing was taken as an example,and a refined hierarchical and household modeling of build⁃ings was conducted along the roads.The construction methods and practical applications of the models in major event secu⁃rity were systematically elaborated.Two modeling methods,namely vector drawing and 3D laser scanning,were studied,and a comparative analysis was conducted from the perspectives of data acquisition methods,modeling costs,operational efficiency,precision control,applicable scenarios,and post-modeling data updates,revealing the advantages and differ⁃ences of different modeling technical approaches.In the practice of major event security,3D building modeling technology demonstrates critical value in applications such as vantage point utilization and multi-perspectiv scenario analysis.
