City-level Real Scene 3D Monolithic Model

Apr 06, 2023

In recent years, due to the maturity of surveying and mapping technology and the government's emphasis on 3D, oblique photography has become an important technology in the rapid growth of geographic information industry. With everyone's recognition of oblique photographic 3D modeling, there is an imminent need for subsequent singulation, attribute linkage, and data modification of oblique photographic 3D modeling.

The Putian Natural Resources Bureau organized the bidding for the Putian aerial photogrammetry project in 2022, and Feiyan Remote Sensing was honored to undertake the specific implementation of the project. One of the contents of the project is to make a 75.1km² real-life 3D model.

This project is based on the 3D model of the real scene and made in DP-Modeler software. The top structure is obtained on the vertical image, and the building facade structure information is obtained on the multi-view oblique image. Pushing, pulling, editing and adjusting it to obtain fine details Monolithic model.Utilizing the feature of oblique photography that the side texture of the building can be collected, the model texture can be automatically collected from the image, and the model texture can be completed with one click, and the texture of the occluded area can be re-shot in the field.
