用于重大活动保障的建筑三维模型构建与应用
3D building model construction and application for major event security
摘要
Abstract
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-perspective scenario analysis.关键词
