【摘要】 以潍坊市主城区实景三维模型制作为例,侧重对倾斜影像实现城市级实景三维模型快速生产的流程、优势与局限、生产效率、模型精度等进行综合分析,针对技术局限,提出了模型精细化修补和三维大场景模型单体化的方法,并对不同单体化方法做出对比分析。实现了实景三维模型自动生产、模型精细化修补、单体化并挂接属性,为实景三维地理信息系统的实现提供技术支撑,对城市级三维模型建立后期应用进行了总结,对为山东省智慧城市建设提供高精度的实景三维数据具有实践意义。更多还原

【Abstract】 In order to make Jinan City real 3D model as an example,focus on the comprehensive analysis of the image tilt to achieve rapid production of three-dimensional model of city level real processes,advantages and limitations,the production efficiency and the accuracy of the model. Summarizes the three-dimensional model of city level establishment of late application,wisdom of the city in Shandong province to provide real 3D data with high precision has practical significance.更多还原
