In close range oblique photography, there are problems of structural adhesion and distortion of 3D model caused by dead angle of aerial photography. In this study, based on a large number of close range images, the technology uses image processing techniques such as feature line matching, point cloud matching, texture mapping to fill in the blind area generated by oblique photography, so as to further optimize the structure and texture of the corresponding near earth model, realize the fine reconstruction, and solve the problem that it is difficult for the oblique photography model to browse near the ground. Comparative experiments show that the proposed method can improve the effect of close range correction to a certain extent and improve the visualization effect of oblique photography digital 3D imaging, thus providing reference for obtaining high-quality and high-precision 3D real scene model.
