Research on 3D modeling of real port scene based on oblique photography
In order to improve the accuracy and efficiency of 3D modeling of real port scene that are covered by a large area of water,a specific port project was used as an example to introduce the oblique photography technology of consumer-grade UAV.Through aerial photo collection,preprocessing of uniform light and color,aerial triangulation,and model reconstruction,a 3D model of the port with real colors and high accuracy was obtained.An improved OTSU algorithm was proposed to extract the complete range of water bodies,effectively repairing the water surface voids in the 3D model.Finally,close range photography was used as an auxiliary method to refine the modeling of some small ground features.The final 3D model of the port obtained in this paper has a good effect and provides important support for the feasibility applying this technology to ports.
