How to build 3D Models for The Oblique Photography with Ground Reshot

Oct 26, 2022

Due to the limitations of flight height and angle of oblique photography, problems such as voids, adhesions, deformations and texture blurring will occur at specific angles of buildings when modeling 3D real scene. With the application of real 3D models becoming more and more widespread, mapping and geographic information services have put forward higher requirements on the quality of real 3D models. Ground reshooting is an effective method to solve this problem.

Images of the shops on the ground were captured by the drone and processed with ContextCapture Center software. In order to fuse the model with the original 3D model, it is necessary to measure points on the original model as control points and add them to the aerial triangulation of the ground shop image.

The model generated by data fusion can not only truly represent the geomorphology of the survey area, but also better express the details of features.
