Reconstruction of Rectangular Plane in 3D Space UsingDetermination of Non-vertical Lines from HyperboloidalProjection

摘要

This paper describes the 3D reconstruction of planar objects usingrnparallel lines from single panoramic image. Determination of non-vertical linesrnis depends on position of vanishing points with two lines on panoramic image.rnThe vertical 3D line is projected as radial line on panoramic image and horizontalrnline is projected as curve or arc in panoramic image. Two parallel verticalrnlines are converged on center point in calibrated panoramic image. On the contrary,rntwo parallel horizontal lines have the pair of vanishing points on the circlernat infinity in panoramic image. We reconstruct the planar objects with parallelrnlines using the vanishing points and properties of parallelism in lines. Finally,rnwe analysis and present the results of 3D reconstruction of planar objects byrnsynthetic or real image.
