  7. Abstract:
  8. Nowadays in movie and photography industry, scene reconstruction is of high importance. Capturing data containing the depth information of the scene can help us achieve this goal more easily. Ordinary Cameras do not record depth information of the scene so they can’t ease our task. In 2005, some Stanford Researchers, inspired by Adelson’s work, were able to build the first camera that captures depth information. They called it the light filed camera. In these cameras an array of microlenses is inserted below the main lens. By doing this the camera is able to capture the rays’ intensities and their directions in space too. With this kind of information, we are able to obtain the depth of a scene and also refocus the picture even after capturing it. If we have multiple number of such cameras, we can reconstruct the 3D model of the scene. In this project, with the help of Lytro camera, we capture multiple pictures from different angles of the scene. Next, the depth map of each light field picture is obtained and then some techniques are introduced to improve these depth maps. In the end, relative location of camera in every picture is estimated with respect to a reference picture and then the 3D model of the scene is reconstructed
