A 3D Spherical Panorama Modeling Method Based on Double Projective Geometry

A 3D spherical panorama modeling method based on the principle of multi-view geometry is proposed in this study to solve panoramic measurement. First, this method uses homography and essential transformations to obtain parameters. Second, it establishes a double spherical projection geometric relationship to complete relative orientation. Third, the conversion parameters of the relative orientation between this method and close-range photogrammetry are derived and compared. Experimental results show the feasibility of the method proposed in this study.
