Study on Panoramic Modeling of Smart Port Based on 3D Video Fusion
Aiming at the problems of poor linkage between surveillance video images in port areas and lack of three-dimensional visual experience,a port panoramic modeling method based on three-dimensional video fusion is proposed.Firstly,based on oblique photography,the port area is reconstructed in 3D,and the point cloud data is pro-cessed by the voxel filtering method during the reconstruction process to construct a lightweight model.Secondly,an improved SURF(Speeded-Up Robust Features)algorithm is proposed to perform image similarity registration to solve the camera pose and realize the fusion of three-dimensional models and videos.Finally,taking a port in Wuhan as the experimental area,the visual rendering of the three-dimensional panoramic model is realized based on the Ce-sium open-source engine.The results show that the proposed method can project the port surveillance video stream into the real scene model in the form of texture,construct a three-dimensional panoramic model with real-time video data,solve the existing problems of port monitoring,and provide a new idea for realizing the three-dimensional moni-toring of smart ports.
