| Abstract: | In this paper, the improvement effect of multisource data fusion on oblique real 3D reconstruction has been studied. Taking Tengzhou city government building as the research object, the data acquisition of vehicle mobile measurement and tilt photogrammetry has been carried out. The theoretical accuracy of each data is analyzed and multisource data fusion is carried out, and then the real 3D model is reconstructed based on the fusion results. By comparing the effect of real scene 3D model based on tilt photography alone, the accuracy of multisource data fusion and the effect of model improvement are analyzed. In addition, automatic extraction technology of feature vector elements has been innovatively adopted based on vehicle movement measurement results, tilt aerial photography difference decomposition has been carried out combining with the data of domestic Beidou base station. It will improve wide application of real scene 3D modeling technology. |
