3D Scene Reconstruction from Images
Tato bakalářská práce se zabĂ˝vá rekonstrukcĂ scĂ©ny pomocĂ RGB--D senzoru Microsoft Kinect. CĂlem práce je z nasnĂmanĂ˝ch dat vytvoĹ™it model mĂstnosti ve formÄ› bodĹŻ, ze kterĂ©ho je následnÄ› vytvoĹ™en pĹŻdorys vnitĹ™nĂch prostor, tvoĹ™enĂ˝ čárami. Z velkĂ© části se práce zabĂ˝vá registracĂ jednotlivĂ˝ch snĂmkĹŻ (mraÄŤen bodĹŻ), tedy existujĂcĂmi metodami a jejich popisem. NáslednÄ› projekcĂ bodĹŻ a detekcĂ hran v obraze pomocĂ Houhgovy transfomace. Dále se práce experimentálnÄ› zabĂ˝vá vlivem nahrávánĂ na vĂ˝sledky a takĂ© zda závisĂ na nahrávanĂ©m prostĹ™edĂ.This bachelor thesis deals with scene reconstruction from images using RGB--D senzo Microsoft Kinect. The aim of the work is to create model of the room in form of points from scanned data, from witch is created plan of the interior. A large part of the work deals with the point cloud registration, thus existing methods and their descriptions. Further, a projection of points on a plane and detection of edges in the obtained image are discussed. The work experimentally examines the influence of recording and the recorded environment on results.
Highlighting objects of interest in an image by integrating saliency and depth
Stereo images have been captured primarily for 3D reconstruction in the past.
However, the depth information acquired from stereo can also be used along with
saliency to highlight certain objects in a scene. This approach can be used to
make still images more interesting to look at, and highlight objects of
interest in the scene. We introduce this novel direction in this paper, and
discuss the theoretical framework behind the approach. Even though we use depth
from stereo in this work, our approach is applicable to depth data acquired
from any sensor modality. Experimental results on both indoor and outdoor
scenes demonstrate the benefits of our algorithm
