Bandara, P.B.M.M.A.Wickramarathna, S.D.H.S.2021-02-102021-02-1020122235-9877http://www.erepo.lib.uwu.ac.lk/bitstream/handle/123456789/5929/335-2D%20to%203D%20Image%20Visualizer.pdf?sequence=1&isAllowed=yThe ordinary photographs are only considered about just an individual photograph itself. Since these photographs act individual character in a scene there is no way to visualize a connection between them. Also browsing of each captured photographs is not relative to other though these photographs are in the same scene. But there is a possible way to reorganize the relative position and orientation of ordinary photographs which are captured by a digital camera device. That is, reorganize the important features on each photographs using feature detection algorithm, then match each photograph by matching these features, then estimate the relative camera pose against each photograph in order to calculate relative replacement and orientation of each photographs on 3D environment. It is useless to calculate the 3D replacement without visualizing them, because the real world scenes are in 3D environment. Therefore, 3D visualizer, to visualize all calculated photographs is developed with very user friendly and interactive way. This project is to develop a system for interactively browsing and exploring unstructured collections of photographs of a scene using a three-dimension interface.enComputer science and TechnologyComputing and Information ScienceOther
