摘要

城市形象反映了一个城市的综合竞争力,也是衡量一个城市精神文明程度和城市化进程的重要标志。良好的城市形象是城市的无形资产,可以为城市的政治、经济、文化、社会建设做出贡献,为城市创造更多的价值。本文主要论述了国内外城市形象的研究现状和研究方法。根据几何光学中楔形衍射的计算方法,对各种有耗楔形均匀衍射的启发式公式进行了比较分析,给出了较好的有耗楔形均匀衍射的启发式公式。最后,讨论了传播通道中重要通道参数的选择,提出了一种基于光线追踪结果预测城市图像传播通道统计参数的方法。然后,利用统计参数对通道参数进行分析,对城市图像传播模型的通道参数进行分析。

Analysis of the Relationship of Video Text and Urban Image Communication Based on the Calculation Method of Wedge Diffraction in Geometrical Optics
City image reflects a city’s comprehensive competitiveness and is also an important indicator of a city’s spiritual civilization and urbanization process. A good city image is an intangible asset of a city, which can contribute to the political, economic, cultural, and social construction of a city and create more value for the city. This paper mainly discusses the research status and research methods of urban image at home and abroad. Based on the calculation method of wedge diffraction in geometrical optics, various heuristic uniform diffraction formulas of lossy wedge are compared and analyzed, and a better heuristic formula of uniform diffraction of lossy wedge is given. Finally, the selection of important channel parameters in the propagation channel is discussed, and a method for predicting the statistical parameters of the propagation channel of urban images based on the results of ray tracing is proposed. Then, the channel parameters are analyzed by using statistical parameters, and the channel parameters of the city image propagation model are analyzed.
