摘    要:实景三维城市已成为三维空间支撑基础设施,是新型基础设施建设的重要内容,地市级实景三维城市建设是全面构建实景三维中国的基础。本文结合实景三维临沂的建设,提出了在低重叠度下,激光点云与倾斜摄影多源数据深度融合技术快速构建城市级实景三维城市的技术流程与体系,其数据成果在大比例尺地形图测绘、智慧临沂时空信息云平台建设、三维不动产登记管理等方面被深入应用,对推动城市级实景三维城市建设及应用具有实践意义。

关 键 词:实景三维城市  倾斜摄影  单体化模型  大比例尺地形图  三维不动产

Abstract:Real 3D cities have become 3D space supporting infrastructure and an important part of the construction of new infrastructure. The construction of real 3D cities is the basis for the comprehensive construction of real 3D China. This paper combines the construction of real 3D Linyi, and proposes the deep fusion technology of laser point cloud and oblique photography multi-source data with low overlap to quickly construct the technical process and system of city-level real 3D city. The data results have been deeply applied in large-scale topographic map surveying and mapping, the construction of the spatio-temporal information cloud platform and the management of 3D real estate registration, which is of practical significance for promoting the construction and application of city-level real 3D cities.
Keywords:real 3D city  oblique photography  singular model  large-scale topographic map  3D real estate
