Key aviation technology of 3D real scene model of super high-rise building
Oblique photography has been applied to all walks of life to establish 3D real scene models.However,there are many densed high-rise buildings,and large height differences among these buildings in the densely populated area,and there exists a general problem of incomplete texture data of the build-ing bottom.Moreover,the pulling,hollow and distortion of 3D real scene model will become more and more obvious with the increase of building height differences.For the problems above,three key technologies of airborne flight,including layered flight,surrounding flight and ground close-up,from the source of field industry flight is proposed in this paper to optimize the quality and accuracy of 3D real scene modeling of super high-rise buildings.The results are verified by three real scenes.The results show that the combined use or single use of these three key technologies,supplemented by supplementary shooting methods can improve the quality of field industry flight results and ensure the coordination and consistency of large urban scenes.
