A 3D Reconstruction Method of Virtual Port with Multi-source Data Fusion
Aiming at the technical defects of tilt photography technology in port 3D reconstruction,a modeling method combining UAV tilt photography with near-surface photogrammetry was proposed to construct a virtual port 3D scene.For multi-source point cloud data,firstly,voxel filtering was used for downsampling,and then dense point cloud data fusion was realized by coarse registration based on sampling consistency initial registration algorithm and fine registration based on KD-tree im-proved point-to-plane ICP(iterative closest point)algorithm.Finally,the fused point cloud data was used for 3D reconstruction.The research shows that this method has greatly improved the quality and accuracy of the model compared with oblique photography modeling,and the model error meets the I-class product standard,so it can be used to construct the virtual port three-dimensional scene.
