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.

Key words: real 3D city, oblique photography, singular model, large-scale topographic map, 3D real estate
