Realistic 3D Modeling Based on Multi-scale Image Data Fusion
A modeling method that integrates multiple sources of data(oblique images,close-range images,and near-ground images)is proposed for establishing a refined realistic 3D model of a large area.The reasons for the defects of the product of the individual ob-lique image data model are analyzed,and the feasibility of refined modeling is analyzed from the perspective of multi-source data fu-sion modeling;on this basis,the three-dimensional modeling of the"three-line"delineation of the ecological protection of Erhai Lake in Dali is taken as an example,the feasibility of application of multi-source data fusion modeling method in practical projects was verified,and large-scale realistic 3D models of key areas were obtained;finally,a comparative analysis was conducted on the model's performance and accuracy.The results indicate that this method can meet the requirements of refined modeling.
